SAP ALE Idoc

Introduction to EDI and ALE:
• EDI (Electronic Document interchange) - EDI is the electronic
exchange of business documents between the computer systems of
business partners, using a standard format over a communication
network.
EDI is also called paperless exchange.
• Advantages:
• Reduced Data entry errors
Reduced processing time
Availability of data in electronic form
Reduced paperwork
Reduced Cost
Reduced inventories and better planning
Standard means of communications
Better business process

• ALE : Application Link Enabling.
• Used to transfer data from one location to another or one
server to another server or one client to another client.
• IDOC: its like a data container or packet which holds the
data.
 IDOC doesn’t have any direction. We need to specify the
direction by specifying sending & receiving logical
systems.
 3 types of record.
1. Data record (EDIDD): Actual business data.
2. Control record (EDIDC): Which message type, sending
system , receiving system
3. Status record (EDIDS): IDOC status messages.

• EDI has two process
1. Outbound process
2. Inbound process
• Outbound Process:
1.Application document is created.
2. IDOC is generated
3.Idoc is transferred from SAP to Operating system layer
4.Idoc is converted into EDI standards
5.Edi document is transmitted to the business partner
6.The Edi Subsystem report status to SAP

• Inbound Process:
1.EDI transmission received
2.EDI document is converted into an IDOC
3.IDOC is transferred to the SAP layer
4.The application document is created
5.The application document can be viewed.
• PORT:
Port is used in the outbound process to determine the
name of the EDI subsystem program, the directory path
where the IDOC file will be created at the operating
system level, the IDOC file names and the RFC
destinations.

• RFC Destination:
Used to define the characteristics of communication links to a remote
system on which a functions needs to be executed.
• Partner Profile:
Partner profile specified the various components used in an outbound
process (Partner number, IDOC type, message type, Port, Process
code), the mode in which it communicates with the subsystem (batch
or immediate) and the person to be notified in case of errors.

• On both sides:
Logical System Names SALE
Setup RFC destinations SM59
Port Destinations WE21
• In Source system:
Segment Creation WE31
Basic IDOC Type Creation WE30
Message Type Creation WE81
Assign Message Type To Basic IDOC Type WE82
Distribution Model BD64
Writing Report Program SE38
Partner Profile WE20
Message control NACE
Check IDOCs WE02, WE05

• In Destination System:
• Creating FM SE37
• Assign FM to Logical Message WE57
• Define I/P method for Inbound FM BD51
• Create Process Code WE42
• Generate Partner Profile BD64

IDOC processing in the same instance of R/3 Clients.
• For example two clients in the same R/3 instance.
• Client 800.
• Client 810.
• To transfer the data between two clients the table
structures and their data types should be match.
• In this example, Client 800 is Source system, and Client
810 is destination system.
• In Client 800 I have created a customized table and
inserted some records.
• In Client 810 I have created only table.

• Common Steps in Both Clients:
• Creating the Logical System Names and Assigning to
Clients:
Go to TCODE SALE.
IMG path IDoc Interface / Application Link Enabling (ALE)
-> Basic Settings -> Logical Systems -> Define Logical
System

Click on Display / Change Button .

Specify the Logical System name and description.
• Note: Logical System Naming convention is
<SID>CLNT<NNN>

• Click on Save and Back buttons
• Now you will come back to the IMG path screen. Click on
Assign Logical System to client.

Click on Display / Change Button

eCATT: The Extended Computer Aided Test Tool
• eCATT: The Extended Computer Aided Test Tool is an
automated testing tool that allows you to create automated
functional test cases for the majority of applications running in
SAP GUI for Windows/Java/HTML or Web Dynpro
environments. Like other test tools, it works by making a
recording of an application, which you can then parameterize
and replay with differing sets of input values. You can test the
behavior of the application by reading and testing the values
returned by the application.
•
• eCATT differs from external tools in that it provides full access
to the application server and database layers of the system,
allowing you to test function modules, BAPIs as well as Web
Services, perform checks against the database, and interrogate
or simulate changes to customizing settings

Go to TCODE SALE. Direct TCODE SM59.
