Do Not Use Database Tools to Modify Oracle Applications Data
Oracle STRONGLY RECOMMENDS that you never use SQL*Plus, Oracle Data
Browser, database triggers, or any other tool to modify Oracle Applications data unless
otherwise instructed.
Oracle provides powerful tools you can use to create, store, change, retrieve, and
maintain information in an Oracle database. But if you use Oracle tools such as
SQL*Plus to modify Oracle Applications data, you risk destroying the integrity of your
data and you lose the ability to audit changes to your data.
Because Oracle Applications tables are interrelated, any change you make using an
Oracle Applications form can update many tables at once. But when you modify Oracle
Applications data using anything other than Oracle Applications, you may change a
row in one table without making corresponding changes in related tables. If your tables
get out of synchronization with each other, you risk retrieving erroneous information
and you risk unpredictable results throughout Oracle Applications.
When you use Oracle Applications to modify your data, Oracle Applications
automatically checks that your changes are valid. Oracle Applications also keeps track
of who changes information. If you enter information into database tables using
database tools, you may store invalid information. You also lose the ability to track who
has changed your information because SQL*Plus and other database tools do not keep a
record of changes.

Manufacturing Scheduling
This chapter covers the following topics:
• Overview of Manufacturing Scheduling
• Constraint-Based Scheduling
• Manufacturing Scheduler Workbench Navigation
Overview of Manufacturing Scheduling
This chapter introduces Oracle Manufacturing Scheduling and describes the
constraint-based scheduling engine, the Scheduler Workbench, and the menus and
toolbar associated with the workbench.
The Oracle Manufacturing Scheduling application is a Work in Process web-based shop
floor scheduling solution. Oracle Manufacturing Scheduling consists of two major
components:
• Constraint-based scheduling engine
• Scheduler Workbench
The constraint-based scheduling engine schedules jobs and operations based on
user-predefined objectives, priorities, resources, and material constraints. You can
reschedule single jobs and operations or the entire shop floor.
The Scheduler Workbench lets you graphically view and reschedule single jobs and
operations based on constraints, such as resource or material shortages. It provides you
with a visual display (Gantt chart) of jobs on the shop floor. You can interactively
reschedule jobs, operations, and resources. You can manually control the rescheduling
or let the system automatically optimize the schedule based on resource and material
constraints. The Scheduler Workbench interfaces directly with Oracle Work in Process.
See: Manufacturing Scheduling Workbench, page 1-4.
Oracle Enterprise Asset Management (eAM) utilizes the Oracle Manufacturing
Scheduling application to schedule eAM work orders and operations. See: eAM

1-2 Oracle Manufacturing Scheduling User's Guide
Scheduling, Oracle Enterprise Asset management User's Guide, and Enabling eAM
Scheduling, Oracle Enterprise Asset Management User's Guide.
Oracle Process Manufacturing (OPM) is also integrated with Oracle Manufacturing
Scheduling. Processing batches can be scheduled to equipment to avoid resource and
component constraints. A scheduling workbench is provided that is specific to Process
Manufacturing environments.
Features
The Manufacturing Scheduling product provides the following features:
• Graphically view shop floor jobs, operations, and resources
• User friendly drag and drop mechanism to reschedule jobs, operations, and
resources
• Fully integrated with Oracle Work in Process
• Ability to select the primary objective of work in process scheduling
• Ability to schedule jobs based on available resources and material
• Ability to reschedule jobs due to resource and material shortages (machine
breakdown, employee sickness, material availability)
• Ability to maintain schedules
• Adjustable bucket sizing that affects the Gantt chart and associated resource load
versus capacity view
• Simultaneous and alternate resources invoked during high demand or when a
resource is unavailable
• Ability to simulate capacity changes, or dragging and dropping to simulate load
changes on the Scheduler Workbench
• Modeling features for creating a prototype for scheduling
• Minimum transfer quantities for operations to move a portion of some assemblies
to a subsequent operation rather than waiting for the entire quantity to complete
• Resource batching to use resources across multiple jobs simultaneously, preventing
a resource from being under utilized
• Ability to dispatch jobs to instances of machines
• Ability to group and sequence jobs based on setup changeovers

• View job related sales order and customer information on the workbench
• Oracle Shop Floor Management enabled so you can schedule discrete jobs on the
Scheduler Workbench created in lot based organizations
• Integrated with Oracle Enterprise Asset Management for scheduling maintenance
of assets
Constraint-Based Scheduling
The constraint-based scheduling engine factors resource and material availability when
scheduling and rescheduling jobs and operations.
The constraint-based scheduling engine lets you:
• Schedule single discrete jobs and operations
• Reschedule all jobs on the entire shop floor
Scheduling Single Discrete Jobs
When each discrete job is created and saved, you receive a request ID. When the request
has completed, you can view the updated start and completion dates of your job and
operations.
If you enter a start date, the system calculates a completion date when the
constraint-based scheduling engine runs. If you want a different completion date than
the calculated completion date to drive the scheduling of your job, specify that date in
the Requested Due Date field on the Scheduling tab of the Discrete Jobs window.
If the constraint-based scheduling engine cannot meet your requested start date or
calculated start date (if you specify a completion date the system calculates the start
date) due to resource and/or material availability, it schedules the job in the first
available time slot where resource and/or material are available. Planned material
receipts are calculated.
If resources and material are not available within the current scheduling horizon, your
job will be scheduled at the end of the scheduling horizon and you might receive an
exception message in the Oracle Application request log. If a job requires two resource
instances, but only one is available, the operation resource starts beyond the end of the
scheduling horizon.
See: Creating and Scheduling a New Job, page 4-1.
Rescheduling All Jobs
When you reschedule all jobs, the constraint-based scheduling engine uses the
requested due date and scheduling priority. The highest priority jobs are scheduled

first. Jobs with the same priority are scheduled based on the earliest requested due date.
Firm jobs and any associated operations are not rescheduled. If a job requires two
resource instances, but only one is available, the operation resource starts beyond the
end of the scheduling horizon.
See: Rescheduling All Jobs, page 6-2.
Manufacturing Scheduler Workbench Navigation
The Scheduler Workbench enables you view all jobs on the shop floor. You can
interactively reschedule jobs, operations, and resources. The workbench comprises four
panes:
• Top left pane: Tree Hierarchy (default)
• Top right pane: Gantt Chart (default)
• Bottom left pane: Select Resource(s)
• Bottom right pane: Resource Load Versus Capacity
The Scheduler Workbench defaults to the Tree Hierarchy and Gantt Chart panes. The
Select Resource(s) and Resource Load Versus Capacity panes appear when you choose
Show/Hide Resource Load on the toolbar. A Status bar, that appears at the bottom of
the window, indicates the current scheduling mode of operation and also displays
message.

Tree Hierarchy Pane
This pane displays the contents of the workbench. There are three levels of information
or branches in the hierarchy of the tree: job, operation, and resource. The Tree Hierarchy
is dynamically created when you launch the workbench, which defaults to show only
unreleased, released, and on hold jobs. You can update the display at any time by
choosing Revert and Refresh on the toolbar. You can also choose the Filter button to
display specific jobs in the Tree Hierarchy pane and corresponding Gantt Chart pane—
used when issues such as machine breakdown, component shortage, or absent
employees impact the schedule. See: Filtering Jobs, page 3-2.
Expanding and Collapsing Jobs or Operations
You can expand a job and its operation(s) in the Tree Hierarchy pane to view the
associated resources. Likewise, you can collapse an operation or job in the Tree
Hierarchy.
• To expand a job:
Point and click on the (+) symbol next to a job.
The job expands showing the respective operation(s). The symbol next to the
selected job changes to (-); the symbol next to the operation is (+).

• To expand an operation:
Point and click on the (+) symbol next to an operation.
The operation expands showing its associated resources(s). The symbol next to the
selected operation changes to (-).
• To collapse an operation:
Point and click on the (-) symbol next to an operation.
The operation collapses. The symbol next to the selected operation changes to (+).
• To collapse a job:
Point and click on the (-) symbol next to a job.
The job collapses. The symbol next to the selected job changes to (+).
Gantt Chart Pane
This pane consists of a timeline, that appears at the top, and a horizontal bar chart. The
timeline represents a time axis (bucket) for the horizontal bar chart. The Gantt chart
directly reflects the tree hierarchy. Besides displaying jobs, operations, and resources, it
can also display the setup resources. The left side of a horizontal bar represents the start
date; the right side of a horizontal bar represents the end date. The magenta vertical line
represents today's date, which is located at the left edge of the Gantt Chart pane by
default.
This pane lets you:
• Manually reschedule jobs, operations, and resources, see: Manually Rescheduling
Start and End Dates, page 3-14.
• Automatically reschedule jobs and operations—resources are adjusted according to
the newly realized requirements, see: Automatically Rescheduling Jobs and
Operations, page 3-15.
• View rescheduling activities in the Resource Load Versus Capacity pane by
appropriately choosing Refresh Resource Load on the toolbar— both prior and after
saving changes.
• View property windows for jobs, operations or resources are available in the Gantt
Chart pane. These windows contain information about dates, quantities, and
descriptions of the scheduling data. See: Job Properties Window, page 3-6,
Operation Properties Window, page 3-7, and Resource Properties Window, page
3-7.
• View exception messages related to jobs and resources requiring attention. See:
View All Exceptions Window, page 5-5.

Changing the Timeline
You should change the timeline in the Gantt Chart pane to view at least one complete
operation.
To change the timeline
1. Right click on the timeline.
A drop-down menu appears which lets you increment the timeline in:
• Months
• Weeks
• Days
• Hours
• 30 Minutes
• 15 Minutes
• Horizontal Sliding Bar - Lets you fine tune the bucket width.
• The left-most position shows the minimum bucket width
• The right-most position shows the maximum bucket width
2. Choose the appropriate increment to resize the buckets so that at least one complete
operation is viewable.
Select Resource(s) Pane
This pane consists of resources and resource instances selected through the Select
Resource(s) window. When you choose the Select Resource(s) button, the Select
Resource(s) window appears. This window lets you select the available resources and
resource instances to display in the Resource Load Versus Capacity pane.
Resource Load Versus Capacity Pane
This pane shows the Required resource load versus the Available resource capacity for
the selected resource(s) and resource instance(s) that appear in the Select Resource(s)
pane. This pane shares the same timeline as the Gantt Chart pane and reflects the
rescheduling activity in the Gantt Chart. You can immediately see the resulting changes
on resource loads before saving.
The Required resource load, Available resource capacity, and Overload resource

capacity key indicators appear to the right of the graphic drop-down menu. The key
indicators are:
• Required:Number of units required by the resource for all jobs in that time bucket.
• Available:The number of resource capacity units in that time bucket (all of which
could already be assigned).
• Overload:Number of resource units that are required but already committed.
The graphic drop-down menu provides the following choices:
• Table: Shows in tabular form. The top number represents the Required resource
load; the bottom number represents the Available resource capacity.
• Continuous: Shows a continuous graph. Non-bucketed lines representing Required,
Available, and Overload resources accurate to the minute.
• Bar: Shows a bar graph. The number on the left represents the Required resource
load; the number on the right represents the Available resource capacity.
When you select:
• Table or Bar—the Required and Available key indicators appear
• Continuous—the Required, Available, and Overload key indicators appear
When the Required resource load is greater than the resource capacity, the Required
resource load number appears red.
After a job is completed, any open resource requirements for that job are excluded from
the resource load calculations. This ensures that resource requirements are correct when
scheduling resource capacity.
Note: Resource load includes all shop floor demand, not just demand
displayed on the workbench.
Scrolling and Resizing the Panes
The vertical and horizontal scroll bars let you display all the contents of a pane. You can
resize a pane by dragging the vertical or horizontal border line to the desired position.
When the job/operation bar is dragged off of the window, the horizontal scrollbar will
automatically scroll left or right.
Workbench Menus and Toolbar
The menus provide you with these choices:

Overview of Setting Up
This chapter provides information about setting up Oracle Manufacturing Scheduling
as well as the necessary Oracle Work in Process application functionality.
This section contains an overview of each step you need to complete to set up Oracle
Manufacturing Scheduling. For instructions on how to complete each task, see the setup
sections indicated in each step below.
You may not need to perform some of the steps below if you've already performed a
common-application setup (setting up multiple Oracle Applications products).
Related Product Setup Steps
Oracle Manufacturing Scheduling requires that Oracle Work in Process Release 12 be
set up for discrete jobs. See: Overview of Setting Up, Oracle Work in Process User's Guide.

Setup Flowchart and Checklist
Some of the steps outlined in this flowchart and setup checklist are:
• Required
• Required Step With Defaults
• Optional
Required Step With Defaults refers to setup functionality that comes with pre-seeded,
default values in the database; however, you should review those defaults and decide
whether to change them to suit your business needs. If you need to change them, you
should perform that setup step. You need to perform Optional steps only if you plan to
use the related feature or complete certain business functions.

Setup Steps
For each step, a Context section indicates whether you need to repeat the step.
Defining WIP Parameters
WIP parameters define modes of operation and default values that affect Work in
Process.
Default: Defaults to unchecked Use Constraint Based Scheduler check box.
Default: Defaults to Resource Only in the Constraints drop-down menu.
Default: There is no default for the Horizon (days) field. You need to enter a value.
Context: You need to perform this step initially and as needed.
See: Defining Work in Process Parameters, page 2-4.
Defining WIP Profile Options
You can select either concurrent or interactive processing while defining jobs.
Default: If you skip this step, defaults to Interactive definition inUser Value drop-down
menu.
Context: You need to perform this step whenever you want to change the discrete job
creation definition.
See: Profile Options, page 2-7.
Defining WIP Resource Definitions
You must schedule a resource as Yes, Prior, orNext to enable the constraint-based
scheduling engine to properly calculate the capacity for the resource. You can define

simultaneous and alternate resources to use during high demand or when a resource is
unavailable.
Default: If you skip this step, defaults to No in the Scheduled drop-down menu.
Context: You need to perform this step initially for each resource assigned to an
operation sequence in a routing.
See: Defining WIP Resource Definition, page 2-8.
See: Defining Simultaneous and Alternate Resources, page 2-10.
Setting Up Scheduling Objectives
You select a primary scheduling objective. You can also define penalty factors, resource
setups, and resource instances.
Context: You need to perform this step whenever you want to change your scheduling
objective.
See: Setting Up Scheduling Objectives, page 2-15.
See: Penalty Factors, page 2-15.
See: Defining Resource Setup Information, page 2-16.
See: Resource Instances, page 2-21.
Defining WIP Scheduling Priority
You can select any priority number from 1 to 9999.
Default: If you skip this step, defaults to 10 in the Scheduling Priority field.
Context: If certain jobs have a higher priority, you need to perform this step every time
a job is created from the Discrete Jobs window or prior to mass rescheduling of the shop
floor.
See: Defining WIP Scheduling Priority, page 2-23.
Defining Work in Process Parameters
WIP parameters define modes of operation and default values that affect Work in
Process.
To define work in process parameters
1. Navigate to the Work in Process Parameters window.
The Work in Process Parameters window appears.

Setting Up 2-5
1. Select the Scheduling tab.
1. Check the Use Constraint Based Scheduler check box.
2. From the Constraints drop-down menu select Resource Only or Resource and
Material.
3. Select the primary goal, or objective, of work in process scheduling for your plant.
From the Primary Objective drop-down menu select Maximize Ontime Completion,
Minimize Setup, or Minimize Operation Slack.
The choice of objective determines which unique set of scheduling logic is used on
the shop floor.
4. In the Horizon (days) field, enter a scheduling horizon adequate to calculate your
resources and material.
Note: The scheduling horizon should be at least as long as your
longest job. You should add additional time to take into
consideration future material receipts.

Note: When using this application with an advanced planning
product, you can select a shorter scheduling horizon (as short as
one day is allowed) so as to not override all your planning.
5. Select a simulation set in the Simulation Set field to enable the adjust resource
capacity capability.
Simulation sets are used to link resource changes to available resource capacity for
scheduling and planning. They are defined on the Simulation Sets window. If the
Use in Scheduling field on this window is checked for particular simulation sets,
capacity modifications associated with that set are used when scheduling jobs in
Oracle Work in Process.
When you assign resources to departments, you can use simulation sets for capacity
modifications by defining them on the Capacity Changes window in Oracle Bills of
Material. See: Assigning Resources to a Department, Oracle Bills of Material User's
Guide.
The capacity of shop floor resources can be changed from the Scheduler
Workbench, see: Adjusting Resource Capacity, page 3-11.
6. In the Maximum Penalty field, enter the maximum penalty factor that can be
entered when assigning penalties for scheduling.
7. In the Penalty Per Day Late field, enter the default penalty factor that will be used
in scheduling for jobs not completed by the scheduled due date.
Higher penalties generate attempts in the scheduling logic to circumvent such an
event.
8. In the Due Date Tolerance (days) field, enter the default number of days that
specifies the drop dead date that a job can be delayed during scheduling.
For example, if a job has a requested due date of July 27, 2001 with a due date
penalty of ten per day and a due date tolerance of five days, the maximum the job
can be delayed is July 31, 2001 but the job still pays a penalty of fifty.
9. Save your work.

Profile Options
During your implementation, you set a value for each Oracle Work in Process profile
option used in Oracle Manufacturing Scheduling to specify how the application
controls access and processes data.
Generally, your system administrator sets up and updates profile option values. The
Oracle Applications System Administration User's Guide contains more information on
profile options.
Only one profile option needs to be set for Oracle Manufacturing Scheduling,
WIP:Define Discrete Jobs Form. This specifies the scheduling processing used when
new jobs are created from the Discrete Jobs window.
You can select either concurrent or interactive processing while scheduling jobs.
• Concurrent definition: Best for scheduling multiple jobs. The system does not freeze
while waiting for the execution of a transaction to complete. If you selected
Concurrent definition, the following sequence occurs:
• Bill of Material loads.
• Routing loads.
• Scheduling engine runs in the background. Status is Pending Bill Load unless
an exception is realized.
• If the scheduling engine can schedule the job without any exceptions, the job
will be scheduled. The status may change to Pending Scheduling if an exception
occurs during the scheduling process. You can read any exception messages in
the request log file.
• Interactive definition: Best for scheduling only a few jobs. The system freezes while
the transaction is executing. You can not open any other application. When the job
is scheduled, control returns to you. If you selected Interactive definition, the
following sequence occurs:
• Application momentarily locks you out.
• Bill of Material loads.
• Routing loads.
• Control returns to you while the scheduling engine is running in the
background. The status is Pending Scheduling during this time.
• If the scheduling engine can schedule the job without exceptions, the job is
created in Pending Scheduling status and changed to Unreleased after the

scheduler runs.

Defining WIP Resource Definition
The Constraint–based Scheduling engine provides the ability to schedule jobs based on
available resources and material. Manufacturing Scheduling resources are enabled on
the Resources window in Oracle Bills of Material. You must schedule a resource as Yes,
Prior, orNext to enable the constraint-based scheduling engine to consider the capacity
for the resource.
After resources are defined, you can create other resource managing components
including:
• Simultaneous resources
• Alternate resources
• Scheduling objectives using the components of penalty factors, machine and
resource setups, and resource instances
• Resource batching

3. In the Schedule field select a value for this resource:
Yes: Include this resources when scheduling an operation from a job and calculating
manufacturing lead time for the assembly.
Note: Do not include scheduling the operation or calculating the lead time.
Prior: Include this resource when scheduling a job or schedule by backward
scheduling the previous operation from the end of this resource. Use this option
when setup resources can work in parallel with previous operations.
Next: Include this resource when scheduling a job or schedule by forward
scheduling the next operation from the start of this resource. Use this option when
the teardown of the current operation can overlap with the execution of the next
operation.
Note: If you do not select Yes, Prior, orNext, the constraint-based
scheduling engine will not consider the capacity for the resource.
Note: If you have a change in available resources, you can edit the
Assigned Units field.

Defining Simultaneous and Alternate Resources
Simultaneous resources consist of two or more resources scheduled with the same start
date within a job operation. Alternate resources consist of other resources—or groups of
resources—used instead of the primary resource in the job operation.
In Oracle Bills of Material—you define resources, associate the resources with your
departments, and assign them to routing operations. In Oracle Work in Process, you can
also add and update resources associated with jobs.
Alternate resources are invoked in one of two ways:
• During backward scheduling, when the use of alternate resources is the only means
for a job to complete by the Requested Due Date
• When a resource for an operation is unavailable
See: Scheduling Jobs with Simultaneous and Alternate Resources, page 4-4.
To define simultaneous resources in item routings:
1. Navigate to the Operation Resources window in Oracle Bills of Material.
2. Enter your resource information in the Main tabbed region. See: Assigning
Operation Resources, Bills of Material User's Guide

Setting Up 2-11
3. In the Scheduling tabbed region, enter the same value in the Scheduled Seq field for
all resources that are simultaneous for each sequence.
The schedule sequence number indicates the sequence the resource is to be used—
simultaneous resources have identical values.For example, Resource1 and
Resource2 are treated as a simultaneous resource group for sequence 10 in this
table.
Seq Resource Schedule Seq
10 Resource1 10
20 Resource2 10
In this next example, Resource2 and Resource3 are treated as a simultaneous
resource group for sequence 20.

20 Resource2 20
30 Resource3 20
4. In the Principle Flag check box, optionally designate the resource that is the primary
resource in a group of simultaneous resources.
5. Save your work.
To define simultaneous resources for job routings:
1. Navigate to the Resource Requirements window in Oracle Work in Process.
2. Enter your resource information in the Main tabbed region. See: Adding and
Updating Resource Requirements, Oracle Work in Process User's Guide.
3. In the Scheduling tabbed region, enter the same value in the Scheduled Seq field for
all resources that are simultaneous for each sequence.
simultaneous resources have identical values. For example, Resource1 and
Resource2 are treated as a simultaneous resource group for sequence 10 in this
table.

In this next example, Resource2 and Resource3 are treated as a simultaneous
resource group for sequence 20.
10 Resource1 10
20 Resource2 20
30 Resource3 20
4. Select the Start Dates and times for the resources—these dates must be the same
date for the resources to be considered simultaneous.
Simultaneous resources must begin at the same time, but they may complete at
different times depending the Usage Rate or Amount.
5. Save your work.
To define alternate resources:
1. Navigate to the Alternate Resources window.
This window is accessed from the Operation Resources window in Oracle Bills of
Material, and the Resource Requirements window in Oracle Work in Process when
you choose Alternates.
Note: The Alternates button is active when a value is entered in the
Scheduling Sequence field on the resource record. When adding a
new resource, this field uses the Resource Sequence value as a
default. The Resource Sequence value can be changed, but you can
not use duplicate values.
2. In the Scheduling tabbed region, for each alternate resource, enter a Replacement
Group value.

This is used in grouping several resources together as an alternate resource group.
The primary resource defaults to Replacement Group value of 0.
3. In the Scheduled Sequence field, enter a value.
this value defaults from the Resource Requirements window and is the same value
as the resource it is replacing.

Overview of Scheduling Objectives
You can select the primary goal, or objective, of work in process scheduling in your
plant. The choice of objective determines which unique set of scheduling logic is used
on the shop floor, and can vary from plant to plant. You can define your primary

Setting Up 2-15
objective to minimize slack time between job operations, decrease the number of
changeovers, or maximize ontime completion. Scheduling objectives use the following
in their calculations:
• Penalty factors
• Machine setup models
• Resource setup times
Setting up Scheduling Objectives
You can model your system in a way that reflects your primary scheduling objective
and closely represents how you actually deploy your resources. This allows you to
achieve your job scheduling goals through more effective management of your resource
constraints. To set up your system you need to assign penalty factors, define resource
setup information, and define resource instances.
Penalty Factors
A weighted value, or penalty, can be assigned to occurrences in scheduling. Higher
penalties carried by an event, generate attempts in scheduling logic to circumvent such
an event. For example, an event might be job completion (early or late) as compared to
due date. The wait time between job operations can be assigned a penalty factor.
You have the ability to assign varying penalty values to different changeovers, in order
to sequence production in any order you desire. Doing so results in not only
minimizing changeovers but also reducing the occurrences of the most costly
changeovers.
When you define your items in the Item Master window in Oracle Inventory, two item
attributes can be used to specify the penalty value.
• Inventory Carry—specifies, in units per day, a penalty for jobs that are completed
before they are scheduled to be finished.
• Operation Slack—specifies, in units per day, the penalty for items having lag time
between operations.
To define penalty factors for manufacturing scheduling items:
1. Navigate to the Master Items window in Oracle Inventory.
2. Enter the item master information if this is a new item number. Or select the item
you want to assign a penalty factor if it exists in your item master file.
See: Defining Items, Oracle Inventory User's Guide.
3. Select the Work in Process tab on the Master items window.

4. In the Scheduling Per Day region, enter values for Inventory Carry and Operation
Slack penalties.
• In the Inventory Carry field, enter the units per day signifying the penalty for
jobs completed before they are scheduled to be finished. For example, the
Inventory Carry penalty for a job that is completed early for an item might be
10 per day.
• In the Operation Slack field, enter the units per day signifying the penalty for
items having lag time between operations.
See: Work in Process Attribute Group, Oracle Inventory User's Guide.
5. Save your work.
Defining Resource Setup Information
You can create a performance model for machine and resource setups to include time
from one setup to another, including the time required to perform the work. If one of
your scheduling objectives is to sequence or group jobs based on their required setup,
you can also include a penalty factor—or weighted value—in the scheduling
calculation.
Resources defined in the Operation Resources window can have multiple setup types.
You can define these setup types with an identifying user code or a numerical value.
Any two setup types within a resource can have a transition time and a transition
penalty, which means that the scheduler needs the specified time to transition from the

Setting Up 2-17
former setup to the latter. Also in doing so a certain transition penalty is incurred. This
penalty is used to weigh the relative merits of doing the setup versus delaying the job
versus cycle time.
The setups for a resource are independent of the department that the resource belongs
to.
The setup type for a particular operation resource is defined in the Operation Resources
window. This data displays in the Resource Requirements window during routing
explosion. Setup resources and resource instances are only exploded during scheduling.
Machine and resource setup information is defined in several setup definition windows
in Oracle Bills of Material.
To define machine and resource setup types:
1. Navigate to the Setup types window in Oracle Bills of Material.
2. In the Code field, enter a unique value for this setup type. Optionally you can enter
descriptive information in the Description field.
For example, you may have different codes for setting up and tear down of paint
color changes.
3. Save your work.
The Setup Standard Operations window is used to assign the setup information to the
operation code of a routing
To define machine and resource setup standard operations:
1. Navigate to the Setup Standard Operations window in Oracle Bills of Material.
2. Select a standard operation code where the setup is performed.

3. Select the department where the operation is performed.
4. Enter the minimum transfer quantity of assemblies to move from this operation to
the next.
5. For operations in ATO model or option class routings only, indicate whether the
operation is option dependant. That is, whether the operation is dependant on the
choice of an optional component. See: Overview of Configure to Order, Oracle Bills
of Material Use's Guide.
6. Select your Count Point and Autocharge options. See: Count Point and Autocharge,
Oracle Bills of Material Use's Guide.
7. Indicate whether to backflush components on shop floor moves at this operation in
the Backfulsh check box.
8. Choose the Operation Resources to assign resources to the standard operation. See:

the unit of measure for the duration in the UOM field.
10. Assign a penalty to the changeover if there is one.
11. Select a Standard Operation (optional).
12. Save your work.
Resource Instances
This feature gives you the ability to define specific machines to any of your machine
type resources. You can also define specific employees to any of your labor type
resources. When a resource has instances defined, the system can schedule at that level
and later view the results on the Manufacturing Scheduling Workbench.
For example, you can define all the individual machines belonging to the resource
GRINDERS. An individual grinder machine can then be called out specifically as a
resource requirement and scheduled, and can have its own unique capacity definition.
Resource instances are specified on the Resource Instance window. You can see all
instances for one resource in the Resource Property window—including setup start
date, setup end date, assigned units, effective start date, effective end date, and serial
number.

To enter resource instances:
1. Navigate to the Resources window.
2. For each resource that you want to schedule at the instance level check the Schedule
by Instance checkbox.
When adding machine resources to the department, the Schedule by Instance
checkbox is selected as the default.
3. Choose Instances to navigate to the Instances window.
4. Enter the number(s) for the employee(s) or equipment and serial number(s)
depending on which type of resource it is.

Defining WIP Scheduling Priority
You can select a specific job and enter a requested due date that is different than the
completion date. The system may recalculate the completion date. The requested due
date is user-defined and will never be recalculated by the system. You can also assign a
scheduling priority number for this job. The prerequisite for this functionality is that the
Use Constraint Based Scheduler check box is checked
See: Defining WIP Parameters, page 2-4.

When scheduling multiple jobs the following criteria is used:
• Schedules the highest priority job first—regardless of the date of the Requested Due
Date field. Insures that resources and material are allocated to the highest priority
jobs.
• Prioritizes jobs with the same user-defined priority based on the various penalty
factors defined.
To select the scheduling priority
1. Navigate to the Discrete Jobs window.
3. Optionally, you can enter a date in either the Requested Start Date or Requested
Due Date fields.
The scheduling engine uses the Requested Start Date value to schedule the job from
that starting point for forward scheduling.
The scheduling engine uses the Requested Due Date value to schedule the job from
that ending point for backward scheduling.
4. In the Scheduling Priority field, enter a number ranging from 1 to 9999, with 1 being
the highest priority.
The default priority is 10.

• Filtering Jobs
• Viewing a Property Window
• Showing Select Resources and Resource Load Versus Capacity Panes
• Adjusting Resource Capacity
• Rescheduling Jobs, Operations, and Resources in the Gantt Chart
Overview of Workbench
This chapter explains how to launch the Manufacturing Scheduler Workbench, filter
jobs, change the timeline, and select resources. It also explains how to manually or
automatically reschedule jobs, operations, and resources.
The Manufacturing Scheduling Workbench enables you to select specific jobs, expand
and collapse jobs and operations in the Tree Hierarchy. You can display resources in the
Select Resources pane, and view its capacity and load in the Resource Load Versus
Capacity pane. You can also select a job in the Gantt Chart pane and manually or
automatically reschedule the job and its associated operations or resources.
Launching the Workbench
You launch the workbench by navigating to the Scheduler Workbench window from
the Scheduling Workbench menu item in Oracle Manufacturing Scheduling. The
workbench appears and shows all the jobs in the Tree Hierarchy and Gantt Chart panes.

Filtering Jobs
You can filter jobs when issues such as machine breakdown, component shortage, or
absent employees impact the schedule. You can view a graph or table representing
resource load versus capacity in both bucketed and continuous form. Filter criteria are
used to find jobs that are affected and filter out the jobs that do not meet the criteria.
To filter job:
1. Choose Filter from the tree pane, or the View menu. You can select one or any
combination of values on this window for filtering.

2. You can select a department and resource.
Note: Only departments with jobs defined display in this field.
3. If you select a department or resource, you can choose dispatch information, the
values are:
Immediate Dispatch: Includes all of the job operations that are ready to be worked on
in the department or by the resource (there is a quantity of assemblies in its queue).
Upstream Dispatch: Includes all of the job operations that are to be worked on in the
department or by the resource in the near future (there is a quantity of assemblies
ready to be moved in the previous operation).
4. Optionally select a customer or sales order.
Customer and sales order information is visible on the Scheduler Workbench for all

jobs with sales order references.
5. Optionally, select Work Orders, Assembly, Component Used, Project, and Task
field information.
6. In the Work Order Status region, you can check a value for filtering:
Released: The work has begun and the discrete job is transactable.
Unreleased: The job is planned but not released for work to begin and not yet
transactable.
On Hold: The job is prevented from progressing through the order cycle.
Complete Charges: The job is complete and charges are allowed.
Complete No Charges: The job is complete but charges are not allowed.
7. Use the Filter By Time region if you want to filter by using date criteria. You can
filter by either date or offset days. Check the Enable Date check box to enable these
fields.
If you choose Date, select a starting date in the Start field, and ending date in the
End field. Only jobs that fall within this time period, and other criteria selected,
display. However, jobs that overlap this time period window also display—a job
displays if part of the job is in the selected time window.
If you choose Offset days from today, enter values, in days, to create the time
period window around your system date. For example, if you enter 3 in the Start
field, and 2 in the End field—the jobs will be filtered using a time period window of
5 days. That is 3 days before today's date added to 2 days after today's date.
8. Check the Show jobs with no operations or resources checkbox if you would like to
see those jobs in the Scheduler Workbench.
9. Choose Apply.
The Scheduler Workbench refreshes and shows the selected jobs associated with the
information entered.
Customer and Sales Order Information
If a job is linked to a sales order, you can use sales order and customer numbers as filter
criteria. And you can view job related sales order and customer information on the
workbench. The information is displayed in two areas—on the Job Properties window
and in a tool tip window.
The Sales Order Lines tab of the Job Properties window displays the job and assembly
number; and all sales order information including customers, lines, and due dates. See:
Job Properties Window, page 3-6
When you select a job bar on the workbench with a referenced sales order, a tool tip

window displays:
• The work order, priority, and the job progress information displays in the upper
region
• Date information displays in the middle region
• Customer and sales order displays in the lower region. If this work order is used for
several customers, or sales orders—that information is represented by an ellipsis
after the name or order number. You can view the other customers or sales orders
in the Job Properties window.

Viewing a Property Window
Property windows for jobs, operations or resources are available in the Gantt Chart
pane. These windows contain information about dates, quantities, descriptions of the
scheduling data, and sales order and customer information. See: Job Properties
Window, page 3-6, Operation Properties Window, page 3-7, and Resource
Properties Window, page 3-7
To view a property window
• Left double-click on a job, operation, or resource in the Tree Hierarchy or Gantt

Chart pane
• Right click on a job, operation, or resource.
A drop-down menu appears.
Choose Properties. The property window for the respective job, operation, or
resource appears.
Job Properties Window
The information on the General tab of the Job Properties window originates from the
Discrete Jobs window when you create the job, or derives through job transactions such
as status and revision changes. Defining Discrete Jobs Manually, Oracle Work in Process
User's Guide.
The progress bar displays a value that is calculated by the percent completed of all
operations based on the time of each operation.

The Sales Order Lines tab displays information about all sales order lines linked to this
job. This includes customer, status, and due date information.
Operation Properties Window
The information in the Operation Properties window originates from the Operations
window in Oracle Work in Process, schedule information when you release the job, or
quantity information derived through job transactions. see Adding and Updating
Operations, Oracle Work in Process User's Guide.
The progress bar displays a value that is calculated by the percent completed of the
Scheduled Quantity. Scrap quantity is included with completed quantity in the progress
calculation.
Resource Properties Window
You can display resource information for resources assigned to specific job operations,
or general resource information for resources defined in Oracle Bills of Material.
The information on the Resource Properties window displays resources assigned to a
particular job operation. The data on the General tab originates from the Resource
Requirements window when you assign a resource to an operation. See: Adding and
Updating Resource Requirements, Oracle Work in Process User's Guide.

The Instances tab displays the resource name, the type of instance, the instance names,
and the number of assigned instances.See: Resource Instances, page 2-21.
When you are in the Resource Load view of the Scheduler Workbench, you can display
the resource properties that are defined in Oracle Bills of Material.
To view the Bill of Material resource definition:
1. Select Resource Load from the View menu or toolbar to display the Resource Load
versus Capacity pane. See: Showing Select Resources and Resource Load Versus

Showing Select Resources and Resource Load Versus Capacity Panes
The Scheduler Workbench lets you show or hide job operations from the resources
listed, and the resources in relationship to the capacity available. You can identify
problems for analysis so that tasks can be modified—for example, the order in which
the resource performs these tasks or the shifting the tasks across the other resources.
To show the Select Resources and Resource Load Versus Capacity Panes
Choose Show/Hide Resource Load from the View menu or toolbar.The Select Resources
and Resource Load Versus Capacity panes appear.
To hide the Select Resources and Resource Load Versus Capacity Panes
Show/Hide Resource again from the View menu or toolbar. The Select Resources and
Resource Load Versus Capacity panes do not appear.
Note: The Resource Load Versus Capacity will not change if you filter
jobs in the Gantt chart because the total demand placed on those
resources by all jobs on the shop floor has not changed.
Selecting a Resource
You can select a specific resource. If you are uncertain of the resource name, expand a
job and an operation and view the specific resource of interest. Select a resource bar
with your mouse pointer (yellow text bubble appears which indicates the name of the
resource). The name of the resource is also available on the Resource Properties
window.

To select a resource
1. In the Select Resource(s) pane choose the Select Resources button.
2. The Select Resource(s) window appears.
3. In the Available Resources pane select a resource or an instance.
4. Choose the right arrow button.
The resource appears in the Selected Resources pane.
5. Choose OK.
The name and description of the resource appears in the Select Resources pane and
its corresponding graphic display for the resource appears in the Resource Load
Versus Capacity pane. This represents the resource load for all jobs on the shop
floor requiring this resource. The default graphic view is Table. The Required and
Available key indicators appear.
6. From the graphic drop-down menu choose Continuous.
A continuous line graph appears. The Required, Available, and Overload key
indicators appear.
7. From the graphic drop-down menu choose Bar.
A bar graph appears. The Required and Available key indicators appear.

Adjusting Resource Capacity
You can adjust resource capacity to respond to machine or personnel availability. This
includes:
• Delete or add a day of capacity, adjusting for overtime shifts or shop closures
• Add or delete resource units when either extra resources are obtainable or resources
are unavailable
• Adjust Assigned Units or Usage Rate for the resource on the job routing
Simulation sets are used to link resource changes for scheduling. Simulation sets are
defined, associated to resources in Oracle Bills of Material, and linked to Work in
Process scheduling in Work in Process Parameters window. See: Defining Work in
Process Parameters, page 2-4. There are two methods for adjusting resource capacity:
• Navigate to the Departments window in Oracle Bills of Material, and from there
access the Resources, Shifts, and Capacity Changes windows
• Access the Capacity Changes window directly from the Schedulers Workbench
To adjust resource capacity through Bill of Materials:
1. Navigate to the Departments window from Oracle Bills of Materials. See: Defining a
Department, Oracle Bills of Material User's Guide.
2. Choose Resources to navigate to the Resources window.
3. Select a resource, then choose Shifts.
The Shifts window displays. This window is used to assign shifts to the resource
from those assigned to the workday calendar.
4. Select a shift and choose Capacity Changes to define capacity changes for a shift.
The Capacity Changes window displays. Capacity modifications include adding or
deleting days.
5. Select the designated simulation set defined on the Work in Process Parameters
window. See: Defining Work in Process Parameters, page 2-4.
6. Save your work.
7. In the Scheduler Workbench, select Refresh Resource Load to display your changes.
8. Select Schedule Multiple Work Orders to apply these capacity adjustments to the
shop floor schedule.

To adjust directly from the Scheduler Workbench:
1. Select Resource Load from the View menu or toolbar to display the Resource Load
versus Capacity pane. See: Showing Select Resources and Resource Load Versus
Capacity Pane, page 3-9.
2. Choose Resources in the Select Resource(s) pane. See: Selecting a Resource, page 3-9
.
If the resource is scheduled by instance, and you want to adjust capacity—select the
instance in the Available Resource(s) pane. If you select the resource and not the
instance, the only action you can perform is deleting a day.
3. When the resources display on the workbench, select and right-click on the resource
you want to adjust.
4. Choose Change Capacity. The Capacity Changes window displays.
Note: a resource must be assigned to a department and a shift to
display this window.
5. The Resource and Department fields display the resource name and the department
it is assigned. The Simulation Set field displays the simulation set used to link
resource changes to available resource capacity.
The Schedule by Instance field displays Yes or No depending on whether the
resource has specified instances (machine or labor type). This is set on the
Resources window, the Schedule by Instance checkbox. See: Resource Instances,
page 2-21.

6. In the Capacity Changes region of the window, you can change or add information
depending on the resource definition.
Ifyou selected a resource scheduled by instance, the only available value in the
Action field is Delete a Day. For these resources, access the instance to adjust
capacity.
7. In the Shift field, select available shifts from the list of values.
Shifts are defined on the Shifts window when you are assigning a resource to a
department. See Assigning Resources to a Department, Oracle Bills of Material User's
Guide.

5. Save your work.
Automatically Rescheduling Jobs and Operations
You can automatically reschedule any job or operation. The required resource and
material are used as the determining factor. The automatic scheduler enables you to
specify the start and end dates, forward or backward schedule a job, and schedule an
operation using the midpoint or midpoint forward scheduling method. You can initiate
automatic rescheduling by moving jobs and operations with the mouse pointer or
through the Automatic Reschedule window.
The constraint-based scheduling engine uses your date if constraints allow, or it moves
the job and/or operation forward to the first available time slot as resources and
material are available.

The following is recommended:
• Take a snapshot before rescheduling
• Periodically take a snapshot to ensure the capacities used by the constraint-based
scheduling engine are correct
Note: In automatic mode, you cannot schedule a job or operation if
it is beyond the end of the horizon. See: Scheduling Horizon, page
6-4
To automatically forward or backward reschedule a job using the pointer
1. Toggle or select Automatic/Manual Scheduling from the menu or toolbar.
You can also right click on a job or operation in the Gantt Chart pane, choose
Automatically Reschedule from the drop-down menu, and specify the date and
direction you want the scheduler to use
2. Point at the beginning or end of a job.
3. Grab and drag to the right (forward) or left (backward). The Automatic Reschedule
window appears.
4. Verify date and scheduling direction.
5. Choose Schedule.
The constraint-based scheduling engine uses the selected date or searches for the
first available time slot as resources and material are available.
6. Choose Refresh Resource Load to view changes prior to saving.
7. Save your work.
To automatically forward or backward reschedule a job using the rescheduler
1. Place your cursor on the start (forward scheduling) or end (backward scheduling)
portion of a job, left click on the light blue portion of the job, and drag the job right
(forward) or left (backward).
The Automatic Reschedule window appears.

2. In the Scheduling Direction field select Forward or Backward.
3. Select the start or end date.
4. Choose Schedule.
The job attempts to start on the date requested as constraints allow, or moves
forward until the next available time slot is found. The job's operations and
resources move with the job.
5. Choose Refresh Resource Load on the toolbar to view changes prior to saving.
6. Save your work.
To automatically forward or backward reschedule an operation using the rescheduler
1. Place your cursor on the start or end portion of an operation, left click on the light
blue portion of the operation, and drag the operation right (forward) or left
(backward).
The Automatic Reschedule window appears.
2. In the Scheduling Direction field select Forward or Backward.

3. In the Scheduling Method field select the appropriate method.
Both directions from operation (Midpoint): Reschedules all prior and next operations
when a time slot is found for this selected operation. Prior operations are backward
scheduled, m=next operations are forward scheduled. The constraint-based
scheduling engine looks for sufficient resources to allow the operation to be placed
at its newly desired time slot while finding a time slot for all prior and next
operations—keeping all operations in their original sequence.
Forward from operation (Midpoint Forward): Moves only the selected and next
operations, keeping them in sequence, when a time slot is located to move this
specified operation. Prior operations will not be rescheduled.
Note: Use Midpoint Forward when you have already started a job
and have activity in any operation.
4. Select the start or end date.
5. Choose Schedule.

Overview of Creating, Scheduling, and Importing Jobs
This chapter explains how to create and schedule jobs, and how Oracle Manufacturing
Scheduling accepts all jobs and schedules from Oracle Work in Process— including
ATO (Assemble to Order) jobs.
Oracle Manufacturing Scheduling enables you to maintain the scheduling of discrete
jobs based on resource and material constraints. You use the Work in Process windows
and load program to perform these tasks including the Discrete Jobs window, the
AutoCreate Final Assembly Orders window, and the Import Jobs and Schedules
window.
Note: Oracle Shop Floor Management is enabled so you can schedule
discrete jobs on the Scheduler Workbench created in lot based
organizations.
Creating and Scheduling a New Job
Refer to the Oracle Work in Process task for creating and scheduling discrete jobs. See:
Defining Discrete Jobs Manually, Oracle Work in Process User's Guide and Discrete
Scheduling, Oracle Work in Process User's Guide.

Note: To use the constraint-based scheduling engine to schedule your
jobs, you must check the Constraint Based Scheduling check box on the
Scheduling tab of the WIP Parameters window. You also must
complete all other setup requirements as specified in Setup Steps, page
2-3.
To create and schedule a new job
1. Navigate to the Discrete Jobs window in Oracle Work in Process.
2. Choose New
The Discrete Jobs window appears.
3. Enter the name of a job.
4. In the Type field select Standard.
5. In the Assembly field select an assembly from the List of Values.
6. Enter a class.
7. With the constraint-based scheduling engine active, the Status field is automatically
set to Pending Scheduling. See: Profile Options, page 2-7.
8. Ensure that the Firm check box is not checked.
If the Firm check box is checked the job will not be automatically rescheduled.
9. In the Quantities region enter a quantity in the Start field.
10. In the Dates region enter a date in the Start or Completion field.

12. Optionally, you can enter a date in either the Requested Start Date or Requested
Due Date fields.
These values are used by the scheduling engine to schedule as close to this date as
possible. The scheduling engine uses the Requested Start Date value to schedule the
job from that starting point for forward scheduling. Or uses the Requested Due
Date value to schedule the job from that ending point for backward scheduling.
13. Optionally, enter a scheduling priority.
14. Optionally, assign a penalty factor in the Penalty Per Day Late field.
15. Optionally, in the Due Date Tolerance (days) field, enter the number of days that a
job can be delayed in scheduling without penalty.
16. Select the other tabs to ensure that there are no other specific user requirements.
17. Save your work.
Resource Instances
If resource instances were defined for a resource used in the job, you can override the
resource instance(s) assigned to the job. Navigate to the Resource Instances window,
select either the Person or Equipment tab, and change the resource instance name.
Note: If a job requires two resource instances, but only one is available,

the operation resource starts beyond the end of the scheduling horizon.
Scheduling Jobs with Simultaneous and Alternate Resources
Simultaneous resources consist of two or more resources scheduled with the same start
date. Alternate resources consist of other resources—or groups of resources—used
instead of the primary resource in the job operation. Simultaneous and alternate
resources in Oracle Manufacturing Scheduling include the following features:
• Two or more resources can be scheduled with the same start date within the job
operation, subject to shift assignments of the individual resource
• You can define more than one group of simultaneous resources in an operation, in
sequential groups
• Simultaneous and standard resources can be combined in an operation
• Simultaneous resources can have different usage rates or amounts—the scheduling
engine restricts all the resources in a set to start at the same time
• You can define multiple resource groups as alternates in a prioritized order—the
scheduling engine tries the first set of alternates, then the second set, and so on
See: Defining Simultaneous and Alternate Resources, page 2-10.
Alternate resources are invoked when there is high demand for the original resource, or
when a resource is unavailable. Oracle Manufacturing Scheduling also provides the
ability to adjust resource capacity. See: Adjusting Resource Capacity, page 3-11.
Creating Final Assembly Orders
You can automatically create final assembly orders for ATO (Assemble to Order) items
entered in Oracle Order Management. You can also associate sales orders to discrete
jobs for ATO items, thereby allocating production to specific customers.
After running AutoCreating Final Assembly Orders, discrete jobs are automatically
scheduled using the constraint-based scheduling engine.
See Also
AutoCreating Final Assembly Orders, Oracle Work in Process User's Guide
Final Assembly Orders, Oracle Work in Process User's Guide
Importing Jobs and Schedules
When importing jobs and schedules you can perform the following tasks:

• Load information into the Work Order Interface.
• Import data from the Work Order Interface.
Note: Jobs are automatically scheduled when they are imported,
unless you set the Scheduling Method to Manual or set
Allow-Explosion to No in the import table before importing the
jobs.
Oracle Manufacturing Scheduling is integrated with Oracle Advanced Supply Chain
Planning. If you have this application installed, Manufacturing Scheduling accepts all
jobs imported by Advanced Supply Chain Planning and does not automatically
reschedule those jobs when they are imported. See: Importing Jobs and Schedules,
Oracle Work in Process User's Guide

Exception Messages 5-1

Exception Messages
• Reviewing Exception Messages
Reviewing Exception Messages
A range of exception messages are provided in Oracle Manufacturing Scheduling so
you can manage your scheduling by displaying jobs and resources requiring attention.
Exception messages may be created after drop and drag scheduling on the Scheduler
Workbench, after creating or scheduling discrete jobs, and after scheduling the entire
shop floor.
For each exception that occurs, you can view the message, where the problem occurred
and the severity, and details of the job. Messages can be one of three types: error,
exception, or warning.
• An error message indicates that the job was not scheduled as shown in this
example:
Oracle Manufacturing Scheduling could not schedule job due to
activity on this job while schedule was running. Please
re-launch the scheduler.
• An exception message informs you about a problem that should be corrected, but
lets you know that the job is not cancelled as shown in this example:
Oracle Manufacturing Scheduling delayed the job because the
requested start date is before today's date.
• A warning message indicates an inconsistency, however the job is still scheduled:
The discrete job completes earlier than the requested due
date.
There are several ways to view exception messages in Oracle Manufacturing
Scheduling:

Navigate to the Scheduling Exceptions window
You can view exception messages for jobs or resources from the Scheduling Exceptions
window. You can view the full text of the exception messages, delete messages, and
mark messages to show that they have been read.
Right click on a job or resource in the Scheduler Workbench
You can view exception messages for a single job or resource by accessing the View
Exceptions window. Right click on any bar, a drop-down menu appears and choose
View exceptions. This window displays in inquiry mode only.
Access the View All Exceptions window from the Schedule menu
This window displays information for all jobs and resources in inquiry mode only.
Scheduling Exceptions Window
To view and process exception messages:
1. Navigate to the Scheduling Exceptions window.
2. Exceptions window, choose Find to show all exception messages. Or limit the
number of records by selecting criteria. See: Using Query Find, Oracle Application's
User's Guide.
You can limit records displayed by selecting values for job, assembly, scheduling
priority, job status, requested due date, scheduling request identification, or error
message severity type.

3. Choose Find to display the Scheduling Exceptions window.
4. Select a job from the Tree Hierarchy pane to view exceptions.
You can view exception messages by either exception or properties.
5. Choose the Exceptions tab to view jobs by exception message.
In addition to the full text of the message, information is displayed in which
operation sequence the exception occurred and the severity.

6. Optionally, you can mark a message to indicate that it has been read. Check the
Marked box if you want to flag the message as read.
7. Choose the Properties tab to view the properties for the job that the exception
message is flagging.

Note: In addition to the Scheduling Workbench, you can access the
Scheduling Exceptions window directly from the Manufacturing
Scheduling menu.
View All Exceptions Window
In the Schedule menu you can also access the View All Exceptions window. This
window displays the same information as shown in both tabs of the Scheduling
Exceptions window—in inquiry mode only.

• Alternate Resources
Overview of Rescheduling Discrete Jobs
When rescheduling jobs you can perform the following tasks:
• Reschedule all jobs using forward or backward scheduling.
• Reschedule jobs with or without a routing reference. For detailed information, see
Rescheduling Discrete Jobs, Oracle Work in Process User's Guide.
• Add, update, delete, reschedule, and view operations. For detailed information, see
Adding and Updating Operations, Oracle Work in Process User's Guide.
• Use midpoint rescheduling to reschedule around a bottleneck job operation. For
detailed information, see Midpoint Rescheduling, Oracle Work in Process User's
Guide.
• Modify discrete job operations, import modified jobs and schedules, and replan
planned orders. For detailed information, see Discrete Rescheduling, Oracle Work in
Process User's Guide.
Some updates and changes made to jobs automatically launch the reschedule process.

This includes changes to:
• Start job quantity
• Start date
• Completion date
• Requested Start Date
• Requested Due Date
• Bill of Material Revision
• Routing Revision
All other changes such as updates to the job heading, routing, bill of material—require
that you manually launch the reschedule process. Refresh the Gantt chart to view these
changes.
Note: When Scheduling All or Pending jobs, the scheduling engine
does not schedule jobs with past due dates, or jobs outside of the
scheduling horizon.
Rescheduling All Jobs
You can access the concurrent program to reschedule all jobs on the shop floor in two
ways. You can navigate to the Schedule Discrete Jobs window, or access the Scheduling
Parameters window directly from the Workbench. When accessed from the workbench,
the workbench passes organization and discrete job information—and you only need to
provide two other fields.
To reschedule all jobs:
1. Navigate to the Schedule Discrete Jobs window.
The Parameters window appears.

2. Select an organization.
3. In the Work Orders field select All Jobs.
The scheduling engine selects jobs with a status of Released, Unreleased, On Hold
that are within the scheduling horizon.
4. In the Scheduling Mode field, select either Forwards from start date or Backwards
from completion date.
5. In the Use Alternate Resources field select either Yes or No. The default is Yes.
6. In the Work Order Type field, select either Discrete job or Maintenance job.
This field defaults to the type of the organization specified in the Organization field.
7. Choose OK. The Schedule Discrete Jobs window appears.
See: Submitting a Request, Oracle Applications User's Guide.
8. Choose Submit.
A Decision window appears which indicates the request identification number. You
can record this number for future reference.
To reschedule all jobs directly from the workbench:
1. Select Schedule Multiple Work Orders from the Schedule menu.
The Scheduling Parameters window displays.

2. Select scheduling method in the Scheduling Direction field.
Your choices are Forward from start date, or Backwards from completion date.
3. In the Use Alternate Resources field—select Yes if you want to consider alternates
in the scheduling run, or No if you want current required resources to be used
regardless of constraint.
4. Choose Submit to start the concurrent program.
A Request identifications number displays at the bottom of the Scheduler
Workbench. When the program is complete, a confirmation window displays.
Scheduling Horizon
When scheduling all jobs, the scheduling engine does not schedule jobs with past due
dates, or jobs outside of the scheduling horizon.
In automatic mode, if you grab and drag to the right (forward) or left (backward).
beyond the end of the horizon—you will not be able to schedule the job. An error
message displays when you choose Schedule on the Automatic Reschedule window,
stating that you must either change the schedule date or cancel the transaction.
See Also
Defining Work in Process Parameters, page 2-4

Automatically Rescheduling Jobs and Operations, page 3-15
Backward and Forward Scheduling
Manufacturing Scheduling supports multiple scheduling methods including backward
and forward scheduling at the job level, and midpoint forward scheduling at the
operation level.
The Scheduling tab of the Resources window is where you define resource scheduling.
The values are Yes, Prior, or Next. If you select Prior, you are including this resource
when scheduling the previous operation. If you select Next, you are including this
resource when scheduling the next operation. Finite scheduling also considers prior and
next operation resources, for example, with fixed setups and teardowns. See: Defining
WIP Resource Definition, page 2-8.
Backward and forward scheduling parameters differ depending on whether you are:
• Entering scheduling data on the Discrete Jobs window
• Rescheduling a single job by dragging and dropping on the Gantt chart
• Employing Alternate Resources
Scheduling Dates on the Discrete Jobs Window
The Discrete Jobs window has two areas holding scheduling date information: the
Dates region on the main region of the window, and the date fields on the Scheduling
tab. These date fields are employed in different ways.
Dates Region
When you initially create a job, you select production dates in the Dates region.
You can forward schedule by specifying a Start date. The constraint-based scheduling
engine begins when the record is saved and moves the job forward to the first available
time slot as resources and material are available.
You can backward schedule by specifying a Completion date. The constraint-based
scheduling engine begins when the record is saved and schedules the job to complete as
close as possible to that date. It calculates a production start date, according to resource
and material availability.

The values in the Date region may change when the record is saved and scheduling
dates are calculated. When the record is saved, these date values and other parameters
(such as whether the job has an assembly routing or not, and is standard or
non-standard) are used for the date calculation. See: Defining Discrete Jobs Manually,
Oracle Work in Process User's Guide. If you are using manufacturing scheduling, the
resource and material constraints are used in the date calculations.
Scheduling Tab Date fields
The dates on the Scheduling tab are the desired, or target, dates you want for
scheduling. When you first create a job, the requested date defaults to date entered in
the Date Region. After you select a Requested Start Date or Requested Due Date, the
scheduling engine uses that date and scheduling constraints—and attempts to meet the
request.
The constraint-based scheduling engine uses the Requested Start Date value to schedule
the job from that starting point for forward scheduling, or the Requested Due Date
value to schedule the job from that ending point for backward scheduling.
The dates in the Date region may change when the record is saved and scheduling dates
are calculated. But the requested dates only change when you manually enter new
values.
Rescheduling the Entire Shop Floor
When you reschedule all jobs on the shop floor from the Scheduler Workbench, the

constraint–based scheduling engine considers:
• Resources and material
• Requested start or due date targets
• Job scheduling priority
• Scheduling objectives
Note: Firm jobs and any associated operations are not rescheduled.
See Also
Scheduling Dates on the Discrete Jobs Window, page 2-4
Defining WIP Scheduling Priority, page 2-23
You can select the primary goal of scheduling. The choice of objective determines the
scheduling algorithm used and is used to maximize ontime completion, decrease the
number of changeovers, or minimize slack time between job operations. Scheduling
algorithms use penalty factors and machine and resource setup models. The scheduling
objective is defined in the WIP Parameters window. See: Defining Work in Process
Parameters, page 2-4, and Setting Up Scheduling Objectives, page 2-15.
Note: When jobs on the shop floor have varying scheduling priorities,
scheduling logic looks at jobs having the same priority when
determining the order operations selected for scheduling. The group of
jobs with the highest priority is scheduled first, then the next highest
priority group is scheduled next, until all jobs are scheduled.
• Maximize Ontime Completion
This scheduling objective employs only backward scheduling and incorporates
penalty calculations including due date, inventory carrying, setup, and operation
slack. See: Penalty Factors, page 2-15. When this objective is used, the algorithm
uses the following logic:
• The last operation of every job on the shop floor, having the same priority level,
is evaluated for penalty factor time totals.
• The cumulative penalty factor of all the jobs is calculated. The job operation
with the highest penalty is scheduled first and allocated resources.
• Then, the last operation—or next to last operation in the job already scheduled,

is evaluated again for penalty factor times.
• The cumulative penalty factor for this next set of last job operations is
calculated. The job operation with the highest penalty is scheduled next and
allocated resources.
• The system evaluates all the job operation sets until the last operation is
scheduled on the shop floor.
• Minimize Setup
This scheduling objective employs both backward and forward scheduling.
Machine and resource setup changeovers, and transition penalty factors are used in
the scheduling calculations. See: Defining Resource Setup Information, page 2-16.
When this objective is used, the algorithm uses the following logic:
• The system evaluates all resources used for jobs on the shop floor with setups
and changeovers, and calculates the transition penalties.
• It then reviews all the operations using this resource, totals all penalty factors,
and selects the operation with the highest penalty aggregate.
• The operation selected is scheduled first.
• Then system again evaluates all resources used for jobs with setups and
changeovers, and calculates the transition penalties.
• It then reviews the remaining operations, not scheduled, using this resource;
totals all penalty factors, and selects the operation with the highest penalty
aggregate.
• The operation selected is scheduled next.
• The evaluation and scheduling continues until all operations are scheduled.
• Minimize Operation Slack
This scheduling objective employs both backward and forward scheduling. It
incorporates calculations including due date, inventory carrying, setup, and
operation slack. See: Penalty Factors, page 2-15. When this objective is used, the
algorithm uses the following logic:
• The penalty factor time for each job on the shop floor, having the same priority
level, is calculated.
• The job with the highest penalty aggregate is scheduled first and allocated
resources. If it is backward scheduled, the scheduling begins at the last
operation of the job. If forward scheduled, the scheduling begins at the first

operation of the job. All the operations in the job selected are scheduled.
• Next, the penalty factors for the remaining jobs on the shop floor are calculated.
• The next job with the highest penalty aggregate is scheduled first and allocated
resources. All the operations in the job selected are scheduled.
• The system evaluates all the jobs on the shop floor until the last job is
scheduled.
Rescheduling a Single Job or Operation
Rescheduling a single job or operation on the Gantt chart using constraint-based
scheduling uses the same scheduling logic as finite scheduling. The scheduling attempts
to meet the due date of the job or operation, setups are sequenced, and slack is
minimized. The difference in rescheduling a single job or operation is that no other jobs
or operations are moved—this can effect your objectives. Start or end dates can be
rescheduled both manually and automatically. You can:
• Midpoint and midpoint forward schedule at a selected operation
• Backward schedule from a previous operation
• Schedule an operation using the midpoint or midpoint forward scheduling method
Automatically Rescheduling Jobs and Operations
The Automatic Reschedule window enables you to specify the start and end dates,
forward or backward schedule a job, and schedule an operation using the midpoint or
midpoint forward scheduling method. The required resource and material are used as
the determining factor.
Select Automatic Scheduling from the menu or toolbar, and use the pointer to
automatically forward or backward reschedule a job.You can forward schedule by
selecting the right of the job or operation bar. Or backward schedule by selecting the left
of the job or operation bar.
The constraint-based scheduling engine uses the selected date or searches for the first
available time slot as resources and material are available. The job's operations and
resources move with the job.
See: Automatically Rescheduling Jobs and Operations, page 3-15
Manually Rescheduling Jobs, Operation, and Resources
You can forward or backward schedule using the pointer or the Edit Schedule window,
enabling you to manually reschedule any job, operation, or resource without regard for
constraints or scheduling rules.

You can forward schedule by selecting the right of the job, operation, or resource. Or
backward schedule by o the left of the job, operation, or resource.
Or you can use the Edit Schedule window to enter new start or end dates for the
required job or operation. The required resource and material are used as the
determining factor.
See: Manually Rescheduling Start and End Dates, page 3-14
Alternate Resources
Alternate resource functionality only employs backward scheduling, because alternate
resources do not use start dates:
• When rescheduling single jobs, the alternate resource is invoked if the primary
resource does not enable the job to complete by the Requested Due Date. It will
revert back to the primary resource if neither the primary or alternate resource can
complete by the date.
• When rescheduling multiple jobs, the scheduling logic looks at the Job Priority,
Requested Due Date, and Completion Date values. The alternate resource is
invoked if the primary cannot complete by the due date. If neither primary or
alternate resource can meet the date, the primary resource is used.

You can assign a scheduling priority number for jobs. The priority value determines the
order resources and material are allocated to jobs. Priority is not considered when a
single job is scheduled or rescheduled. See: Defining WIP Scheduling Priority, page 2-23
.
Alternate Resources
Alternate resources consist of other resources—or groups of resources—used instead of
the primary resource in the job operation. Alternate resources are invoked when
scheduling dates are not feasible due to resource unavailability. See: Defining
Simultaneous and Alternate Resources, page 2-10Alternate Resources, and Scheduling
Jobs with Simultaneous and Alternate Resources, page 4-4.
Simultaneous Resources
Simultaneous resources consist of two or more resources working concurrently within a
job operation, subject to shift assignments of the individual resource. See: Defining
Simultaneous and Alternate Resources, page 2-10 and Scheduling Jobs with
Simultaneous and Alternate Resources, page 4-4.
You can select the primary goal, or objective, of scheduling and model your system to
this application of resources. The choice of objective determines the scheduling logic.
See: Setting Up Scheduling Objectives, page 2-15. Scheduling objectives use penalty
factors. machine and resource setups, and resource instances.
• Penalties for Late or Early Completion and Wait Time
A weighted value, or penalty, can be assigned to scheduling events. Higher
penalties induce the scheduling logic to circumvent such an events. For example,
different changeovers can be assigned various penalties to sequence production in a
particular order.See: Penalty Factors, page 2-15.
• Machine and Resource Setups
You can create a performance model for machine and resource setups to include
changeover time from one setup to another, including the time required to perform
the work. Resources can have multiple setup types. Any two setup types within a
resource can have a penalty assigned to weigh one changeover setup versus the
other. See: Defining Resource Setup Information, page 2-16.
Resource Instances
You can define specific machines to machine resources, and specific employees to labor

resources. The resource instance data is viewable in the Resource Property window—
including setup start date, setup end date, assigned units, effective start date, effective
end date, and serial number. See: Resource Instances, page 2-21.
Capacity Adjustments
Resource capacity can be adjusted to respond to machine or personnel availability. You
can add, delete, or adjust capacity and resource units. Simulation sets are used and
linked to scheduling. They are defined and associated to resources.

Defining Work in Process Parameters, page 2-4
Adjusting Resource Capacity, page 3-11
Minimum Transfer Quantity
Minimum transfer quantities on routings enable you to move a portion of assemblies.
This allows you to complete jobs more efficiently than waiting for the entire quantity to
be completed. See: Minimum Transfer Quantity, page 7-3,.
Resource Batching
Resource batching enables you to use a single resource to process multiple jobs
simultaneously, preventing a resource from being underutilized. See: Resource
Batching, page 7-5.
Minimum Transfer Quantity
You can define a minimum transfer quantity for operations on a routing, enabling you
to move a portion of some assemblies to the subsequent operation. Scheduling with
transfers provides the ability to complete jobs more efficiently than waiting for the
entire quantity to move to the next operation. Scheduling algorithms use the minimum
transfer quantity values; and processing begins before all assemblies are completed at
the current operation.
Setting Up
Minimum transfer quantity functionality is enabled when you enter this value on either
the Standard Operations or Routings windows in Oracle Bills of Material. If the job uses
a standard operation, the value defaults from the Standard Operations window. If the
job uses a routing, either bill of material or work in process routing type, the value
defaults from the Routings window.

Creating a Routing, Oracle Bills of Material User's Guide
Creating a Standard Operation, Oracle Bills of Material User's Guide
Processing Features
Manufacturing begins when a sufficient quantity of the assembly is at the operation
resource. When the quantity is complete, it moves to the next operation resource.
• If this functionality is enabled, the scheduling engine always transfers completions
in batches, and the minimum transfer quantity amount applies to all resources in
the operation.
• This processing does not allow overlapping transfers in the same operation. If a
minimum transfer quantity arrives at an operation resource before the previous
quantity is completed, work does not begin until the first amount is completed.
• The batch amount matches the minimum transfer quantity value. However, the
transfer quantities can differ across transfers in order for the completion to equal to
the sum of the batches. For example:
• If the job quantity is 100,
• And the minimum transfer quantity is 30,
• You can have transfers of quantities 30, 30 and 40 in order to equal the total of
100.
• Transfers are only within operations of a routing.
Note: Network routings do not use minimum transfer quantity
functionality.
• Resource Settings
Prior and Next Operation Resources: If an operation resource is flagged as Prior on the
Resources window, then it can overlap with the previous operation. If it is flagged
as Next, then it can overlap with the succeeding operation. However, minimum
transfer quantity processing does not allow overlapping batches in the same
operation. If you are using minimum transfer quantity batches and they overlap,
the quantities skip the Next or Prior resource—and move to subsequent or
preceding resource in the routing.
Sequential Operation Resources: In sequential operation resources, the transfer
amount determines the schedule of the operation resources. If one of those
resources does not have minimum transfer quantity, the schedule is determined by

the end time of one and the start time of the other.
Simultaneous Resources: Within any simultaneous set, all transfers in an operation
resource coincide.
Resource Batching
Resource batching enables you to use resources across multiple jobs. This prevents a
resource from being underutilized. Work scheduled using resource batching is
equivalent work performed with the same manufacturing processes.
Resource batching creates processing batches which consist of a job/resource
combination, and standard operation code if applicable. For each batchable resource, a
time window is defined when the system should look for operations to include in the
batch.
Note: If using standard operation codes, they must be the same for all
the operations in a batch.
Batching Different Assemblies
You can create a batch that includes jobs of different assembly numbers. The scheduling
engine creates batches across multiple jobs and schedules them as a one group when
they use the same:
• Standard operation code in their routings

• Resource setup
• Time period duration of the resource
They must also fall within the same batching window.
Batch Definition
The resource batching information is defined in the Resources window in Oracle Bills of
Material. See: Creating a Routing, Oracle Bills of Material User's Guide. Check the
Batchable check box to enable a resource for batching, and enter values for the
following fields:
• Maximum Batch Capacity: The largest number of units to group in a batch. If there
are jobs containing units exceeding this value, the system creates multiple batches.
• Batch Capacity UOM: Unit of measure used for the resource batch such as units,
area, volume, or weight.
• Batching Window: The time frame in which this resource is used when batching. For
example, if the batching window value is 3 hours, the resource is available to the
processing batch in this 3 hour window.
• Batching Window UOM: The unit of measure, expressed in time, used for the
Batching Window field.
