Overview of Oracle Approvals Management
The purpose of Oracle Approvals Management (AME) is to define approval rules that determine the
approval processes for Oracle applications..

Approval Rules


An approval rule is a business rule that helps determine a transaction’s approval process. Rules are
constructed from conditions and actions.

The approval rule’s if part consists of zero or more conditions, and its then part consists of one or
more actions. A condition consists of a business variable (in AME, an attribute) and
a set of attribute values, any one of which makes the condition true. An action tells AME to modify
a transaction’s approval process in some fashion
AME enables you to define rules that express a wide variety of approval rules. For example, rules
that:
• Require subject-matter-expert approval
• Require managerial approval
• Create exceptions for rules requiring managerial approval
• Substitute one approver for another in special cases
• Revoke a manager’s signing authority in special cases
• Grant a manager extra signing authority in special cases
• Generate a production that assigns a value to a variable name such as the value digital certificate
to the variable name eSignature.
• Send for-your-information notifications.
You can prioritize the approval rules. This enables you to apply rules of sufficient priority to any
given transaction.

Transaction Types
An application that uses AME to govern its transactions’ approval processes is termed an
integrating application. An integrating application may divide its transactions into
several categories where each category requires a distinct set of approval rules. Each set of rules is
called a transaction type. Different transaction types can use the same attribute name to represent
values that are calculated in different ways or fetched from different places. This allows several
transaction types to share approval rules (thereby implementing a uniform approval policy across
multiple
transaction types). A rule use occurs when a transaction type uses a particular rule for a given time
period, optionally at a given priority level.

A transaction’s approval process can have two components:
• List of approvers


• Set of productions

Approver Lists
A transaction’s approver list has a hierarchical structure. The transaction’s approver list may contain
several items’ approver lists. Each item’s approver list may have three
sub-lists. Of these sub-lists, the authority sub-list can have a chain of authority generated by one or
more action types. Each approver group or chain of authority can contain multiple approvers.
Items
AME can generate an approver list for a transaction’s header, and a separate approver list for each
item in the transaction. A transaction type can define multiple item
classes. For example, a transaction type might generate separate approver lists for each
transaction’s header, line items, and cost centers. All transaction types include a
header item class, which always has one item (the transaction’s header). All other item classes are
optional.
Sub-Lists
An item’s approver list may contain three sub-lists:
• Pre-chain of authority
• Authority
• Post-chain of authority
The pre- and post-chain sub-lists contain zero or more approver groups; the authority sub-list
contains zero or more chains of authority.
Action Types
An action type is a set of actions having a common purpose. Each sub-list can contain approver
groups or chains of authority generated by several action types. For
example, actions in the absolute-job-level action type all generate chains of authority by ascending
the HR supervisory hierarchy until they reach a manager with a particular job level.
The actions differ according to the job levels they require.
Approver Groups
An approver group is a collection of approvers that you define. Typically, approver groups contain
subject-matter experts.
Chains of Authority
A chain of authority ascends a hierarchy of approvers that are normally defined in applications other
than AME, for example HRMS (supervisor position hierarchies). The
start point of the chain, and how far it ascends the hierarchy, usually varies between transactions.
You can also treat an approver group as a chain of authority. In this
case AME ignores the approver group’s group-specific properties. Generally, chains of authority
contain managers. Approver groups and chains of authority behave differently in certain
circumstances.
For example, when one approver forwards a notification requesting approval to another approver.
Otherwise, approver groups and chains of authority behave similarly.
Approvers
An approver has the following two properties:
• Approver Types
An approver type is any Workflow Directory Services originating system that defines entities, which
can receive Workflow notifications requesting an approval. For
example, the HR application defines its set of employees as a Directory Services originating
system, so an HR employee can be an approver.
• Approver Categories
AME can generate approvers belonging to either of two approver categories: action and
informational (for-your-information or FYI) approvers. Action approvers must
approve a transaction. FYI approvers merely receive a notification describing the transaction. The
exact content of all notifications depends on the application that
generates the notification.

Productions


In AME, a production assigns a value to a variable name. For example, AME might generate a
production that assigns the value digital certificate to the variable name
eSignature. AME does not interpret the productions it generates. In fact, AME does not even define
any standard production variable names. Rather, it leaves these tasks
to integrating applications and their transaction types. AME generates two kinds of productions:
• Transaction-level productions that are variable name or value pairs associated with a whole
transaction.
• Approver-level productions are associated with specific approvers within a transaction’s approver
list.

What Happens at Run Time
Once you have defined a set of rules for a transaction type, and the application associated with the
transaction type is configured to use AME, the application communicates directly with AME to
manage the transaction type’s approval processes. Typically, the application communicates with
AME when a transaction is initiated in the application, and then each time an approver responds to
the application’s request for approval of the transaction, until all approvers have approved the
transaction. AME records each approval, and recalculates the approver list for a transaction each
time an approver responds to a request for approval of the transaction.
AME recalculates the approver list each time an approver responds. This enables AME
to account for several possible circumstances that can affect a transaction’s approver list:
• An attribute value changes, thereby affecting which conditions are true and so which
rules apply to the transaction.
• A condition or rule is added, changed, or deleted, again affecting which rules apply
to the transaction.
• A change occurs in the organizational hierarchy used by the transaction type’s set of
rules, thereby changing the membership of the applicable chain of authority.
• Currency exchange rates change, thereby affecting which conditions on currency
attributes are true and so which rules apply to the transaction.
By accounting for such changes, AME guarantees that transactions are always approved
according to the most current business data possible.

Approval Process Execution
Approval-Process Execution
Integrating applications can communicate with AME in many different ways. For example, an
integrating application can ask AME for a transaction’s entire approver
list, for the rules satisfied, or for the set of approvers the application should notify next.
The Standard Algorithm
Typically, an integrating application follows a simple procedure for managing a transaction’s
approval process:
1. Ask AME for a transaction’s entire approver list.
2. Display the approver list to the requestor, optionally prompting them to suppress or add
approvers.
3. Communicate any approver suppressions or additions to AME.
4. Ask AME whether the transaction’s approval process is complete, and if not, what approvers (if
any) to notify.
5. If AME indicates that no further approvals are required, stop.
6. Notify any approvers identified by AME in step 5.
7. Wait until an approver responds to a notification.
8. Communicate the response to AME.
9. Go to step 4.
Approver-Notification Order
The order in which AME presents approvers for notification at step 4 of the standard algorithm
depends on a variety of ordering modes and order numbers that together


determine a unique ordering of the approvers in a transaction’s approver list.An ordering mode tells
AME how to order the collections of approvers at a given level of
the hierarchy constituting a transaction’s approver list. For example, the sub-list ordering mode
basically tells AME whether to notify pre-approvers at the same time as authority approvers, all
other things being equal. AME typically uses ordering modes, before a transaction is submitted to
AME for approval, where the number of things to be ordered is unknown. For example the
approvers generated by a particular action type maybe notified sequentially or in parallel.Order
numbers establish a fixed ordering of a collection of approvers at a given level of the hierarchy
constituting a transaction’s approver list, for example, the approvers in an approver group are
assigned order numbers. Order numbers are not necessarily unique. Thus several approvers in an
approver group can have the same order number. AME typically uses order numbers where you
know the number of things to be ordered before a transaction is submitted to AME for approval.

Implementing Oracle Approvals Management

Configuration Variables
The configuration variables you should consider when implementing approvals business
cases are:
• adminApprover
• allowAllApproverTypes
• allowAllItemClassRules
• allowFyiNotifications
• productionFunctionality
• purgeFrequency


• repeatedApprovers
• distributedEnvironment
• currencyConversionWindow
• rulePriorityModes
• forwardingBehaviors
Mandatory Attributes
The mandatory attributes related to implementing approvals business cases are:
• ALLOW_DELETING_RULE_GENERATED_APPROVERS
• ALLOW_REQUESTOR_APPROVAL
• AT_LEAST_ONE_RULE_MUST_APPLY
• EFFECTIVE_RULE_DATE
• EVALUATE_PRIORITIES_PER_ITEM
• REJECTION_RESPONSE
• REPEAT_SUBSTITUTIONS
USE_RESTRICTIVE_ITEM_EVALUATION
• USE_WORKFLOW
• WORKFLOW_ITEM_KEY
• WORKFLOW_ITEM_TYPE
Approver Groups
You must create or include approver groups in your transaction type.
Rules and Rule Use If your organization has more than a few approvals rules, it can be useful to
represent the rules in an approvals matrix or a decision tree. An approvals matrix is just a table that
had one row per rule.

Implementing Tasks Approvals Management
To implement AME, you need to carry out the following steps:
1. Install the application.
AME’s installation routines and administration features determine which applications can use AME.
Installation and administration are typically jobs for a
technical specialist. Installation is generally done only once, and administrative tasks (using AME’s
Administrator Dashboard) are usually only necessary to enable a new
application to use AME, or to access or clear a transaction’s error log.
2. Set up AME security by completing the following:
• Attach the predefined roles to a user or group of users.
AME uses the Role Based Access Model (RBAC) to provide users access to AME functions. This
access model has the following predefined roles:
• Approvals Management Administrator
• Approvals Management Analyst
• Approvals Management System Viewer
• Approvals Management System Administrator
• Approvals Management Process Owner
Each of the five predefined roles has a specific set of functional grants. The grants provide users
access to AME. To enable functional grants, you must assign roles
to users using the User Management page. For information about accessing User Management
page, see: Oracle Applications System Administrator’s Guide
- Security.
Set up user access as follows:
1. Login as Administrator.
2. Select the User Management responsibility.
3. Select the Users page.
4. Search for the user to whom you wish to grant AME roles.
5. In the results table, click Update. In the Update User page, you can view
user details along with a list of roles available to the user.
6. Click Assign Roles.
7. Select the roles from the resulting list and click Apply.


When you assign any of the five predefined roles to a user, you are indirectly assigning AME
responsibilities to the user. Grant data access to users.As AME restricts access to transaction types
using Data Security, you grant users access to the transaction types using the Grants page. Set up
user access as follows:
1. Login as Administrator.
2. Select the Functional Administrator responsibility.
3. Select the Grants tab.
4. Click Create Grant.
5. Select Specific User as grantee type.
6. Select the user as grantee key.
7. Select AME Transaction Types as object:
1. All rows: This grants access to all AME Transaction Types to the User
2. Instance: This grants access to a specific AME Transaction Type
specified by the following parameters: FND_APPLICATION_ID =>
Application ID of the application to which the transaction type belongs
TRANSACTION_TYPE_ID => Unique identifier of the AME Transaction
type within application
3. Instance set: This grants access to one or more AME Transaction Types
specified by the following parameters:
• Use the predefined instance set AME Transaction Type Instance Set.
• In the next page, select FND_APPLICATION_ID as Parameter1
and a wild card search string for TRANSACTION_TYPE_ID as
Parameter2.
8. In the next page there will be three options for instance type: select AME
Calling Applications as the permission set.
9. Review and Finish.

3. Set the user profile - AME:Installed

4. Configure transaction types.
An application administrator should review AME’s configuration-variable values as soon as AME is
installed and its security has been set up. AME has the following
kinds of configuration variables:
• Single-Valued Configuration Variables AME’s configuration variable distributedEnvironment has a
single value for the entire application. This variable describe various aspects of AME’s computing
environment. You must set its value for AME to function properly.
• Transaction-Type-Specific Variables
Other AME configuration variables can have a default value, as well as a value
for each transaction type. These variables are:
• adminApprover
• allowAllApproverTypes
• allowAllItemClassRules
• allowFyiNotifications
• currencyConversionWindow
• forwardingBehaviors
• productionFunctionality
• purgeFrequency
• repeatedApprovers
• rulePriorityModes
These variables determine many aspects of how AME generates a transaction type’s approval
processes and are similar to the mandatory attributes. The difference is, their values are always
constant for all transactions in the transaction type. Ensure you are satisfied with these variables’
default values before using AME.

Implementing the Transaction Type
To implement the transaction type, you need to specify or create, if required, the following
components of the approval process:


1. Create item-class use (Optional).
2. Create transaction attributes (Optional). In AME, an attribute is a named business variable such
as TRANSACTION_AMOUNT, whose value AME fetches at run time, when it constructs
transactions’approver lists.
3. Create conditions (Optional). In AME, a condition specifies a list or range of attribute values
required to make a rule apply to a transaction. For example:
Example USD1000 < TRANSACTION_AMOUNT < USD5000
4. Create approver groups (Optional).
You can create AME rules to include one or more approver groups in a transaction’s approver list.
5. Prepare to use the action types. You add action types to a transaction type using the Action
Types tab.
• Predefined action and approver types
• Custom action and approver types
• Add approvals to existing approval types
• Preparing to use the Job-Level approval types
6. Define approval rules.
7. Test approval rules.
8. Create custom transaction types.
9. Configure Oracle applications to use AME.

Attributes
Attributes are business variables with a single value for a particular transaction.


Eg select item_quantity from some_application_table where transaction_id = :transactio

Mandatory Attributes
ALLOW_DELETING_RULE_GENERATED_APPROVERS
ALLOW_REQUESTOR_APPROVAL
AT_LEAST_ONE_RULE_MUST_APPLY
REJECTION_RESPONSE
USE_RESTRICTIVE_ITEM_EVALUATION
USE_WORKFLOW
WORKFLOW_ITEM_KEY
WORKFLOW_ITEM_TYPE
Required Attributes
ALLOW_EMPTY_APPROVAL_GROUPS
FIRST_STARTING_POINT_PERSON_ID
INCLUDE_ALL_JOB_LEVEL_APPROVERS
TRANSACTION_REQUESTOR_PERSON_ID

How does AME use Attributes?
When AME starts to calculate a transaction’s approver list at run time, it does the following:
1. It fetches the values of each attribute that is active for the transaction type.
2. After fetching all of the active attributes’ values, AME checks whether each of a transaction
type’s rules applies to the transaction.
Conditions
The if part of an approval rule consists of zero or more conditions. A condition is a statement that is
either true or false, for a given transaction.


There are two types of conditions:
• Regular, which has Ordinary and Exception conditions eg 1,000 <= TRANSACTION_AMOUNT <
2,000
• List-modifiers : A list-modification condition checks for the presence of a given target approver at a
specific set of allowed locations in the default approver list. When the target approver is present in
an allowed location, we say that the default approver list satisfies the condition.
Actions
An action is an instruction to AME to modify a transaction’s approval process in the manner you
specify. Every action belongs to an action type. An action type is a collection of actions having
similar functionality

Approver Groups An approver group can either be an ordered set of one or more approvers
(persons and/or user accounts) or it can be a list, which is dynamically generated at rule evaluation
time. A typical pre- or post-approval rule adds an approver group’s members (in order) to a
transaction’s approver list.

Example
COMP_APP_1 = {Jim Small} COMP_APP_2 = {COM_APP_1, Jane Smith} COMP_APP_3 =
{COMP_APP_2, Liz Large}
AME would evaluate the membership of COMP_APP_3 to be (Jim Small, Jane Smith, Liz Large}, in
that order.
If ITEM_CATEGORY in {COMPUTER_HARDWARE} and ITEM_AMOUNT <= 1,000
USD then require post-approval from the COMP_APP_1 group.
Example
If ITEM_CATEGORY in {COMPUTER_HARDWARE} and 1,000 USD < ITEM_AMOUNT <= 10,000
USD then require post-approval from the COMP _APP_2 group.
Example
If ITEM_CATEGORY in {COMPUTER_HARDWARE} and 10,000 USD < ITEM_AMOUNT then
require post-approval from the COMP_APP_3 group.

ALLOW_EMPTY_APPROVAL_GROUPS. When this attribute has the value ’true’, AME allows an
approver group not to have any members at run time.

when to use an approver group:
Using Approver groups for Pre- and Post-Approvals
Using Approver groups for Chain of Authority Approvals
Approver Group Properties Name, Description, Voting Regime, Active List(statuc & Dynamic
member list)..
Select ’PER:’||person_id from invoice_table where transaction_id = :transactionId and item_class = :itemClass
and item_id = :itemId

Rules : Creating rules and rule use are the main steps in the AME implementation process. Rule
associate one or more conditions with an approval in an if-then statement. Before you can create
rules, you must create conditions for the rules to use. You may need to create (or have a system
administrator create) some custom attributes and/or approvals. You may also need to create some
approver groups.


Rule Types : There are eight rule types in AME. Seven of them provide rules that participate in
generating transactions’ approver lists; these are the approver-generating rule types. The eighth
generates productions.
• List-creation rules If TRANSACTION_AMOUNT < 1000 USD, then require approvals up to at least
job level 2.
• List-creation exceptions If TRANSACTION_AMOUNT < 500 USD and Exception: COST_CENTER
is in {0743}, then require approvals up to at least job level 1.
• List-modification rules If TRANSACTION_AMOUNT > 1000 USD and the final approver is: Kathy
Mawson, then require approvals at least one level up.
• Substitutions If TRANSACTION_AMOUNT < 500 USD and CATEGORY in
{MISCELLANEOUSOFFICE EXENSES} and any approver is: John Doe, then substitute Jane Smith
for the approver.
• Pre-list approval-group rules If TRANS_AMOUNT < 1000 USD and CATEGORY_NAME in
{Marketing Event}, then require pre-approval from Marketing Approvals Group.
• Post-list approval-group rules
• Combination Rules
• Production Rules

Rule Properties : Actions, Start and End Dates, Item Class

The purpose of rule priorities is to prioritize a transaction type’s rules and, at run time, remove
from the set of rules that would otherwise apply to a transaction, those
rules of insufficient priority. A rule priority is a positive integer associated with a rule within a
transaction type.

Planning Your Test Cases (test on AME work Bench)
While planning you implementation strategy, your implementation document, showing your approval
policies, should specify test cases sufficient to verify that your transaction type does the following
things according to your business rules:
• Fetch correct item IDs.
• Fetch correct attribute values.
• Evaluate the rule use correctly.
• Process the rule use priorities correctly.
• Process production rules and actions correctly.
• Produce the correct default approver list.
• For real transactions, handle inserted approvers correctly.
• For real transactions, handle suppressed approvers correctly.
• Process repeated approvers correctly.
• Parallelize a transaction’s approval process correctly.
• Process forwardings correctly.

Administration
The Administrator Dashboard is available only to users with the Application Administrator
responsibility. You can use this dashboard to maintain AME’s
configuration variables and transaction types. Additionally, you can view and analyze AME’s
runtime exceptions.An AME application administrator has many tasks. As an application
administrator, you can perform the following application and transaction-type administrative tasks:
• Set the configuration variables’ default values (application-wide values)
• Set the transaction type’s configuration variables’ values
• Create a transaction type
• Update a transaction type
• Delete a transaction type
• View the exception log
• Clear the exception log


• Run the Setup report
