ALE / IDoc Examples Documents for Novice ABAP Users

This document aims to help the ABAPers to set up the necessary configurations to send IDoc from one system to another. This document will provide developers a good starting point on how to start and where to start after studying all the theoretical aspects of ALE/IDoc.

Scope of scenarios on EDI systems is outside the scope of this document. Also, sending Idoc by message control mechanism is not described here. Not there is any discussion of sending Idoc using BAPI.

ALE Converters and Subsystems

The ALE concept involves using external converters to connect non-SAP systems to the R/3 System.External converters are generic format conversion programs. The following converter functions arecovered by SAP XA-ALE certification:

  • The transfer of R/3 intermediate document (IDoc) formats straight into their own repository so that these data descriptions can be used as source or target structures when assigning data fields.
  • Adoption and conversion of intermediate documents from R/3 Systems via the ALE interface —a remote function call that can be called up using a normal transaction.
  • Conversion of any data format into intermediate document structures and import into the R/3 System via a remote function call in the ALE interface.

Error Handling Through Workflow

With this material you will get details of Error handling of an Inbound Idoc through triggering an event, which in turn will be triggering a workflow attached to the workflow.

Steps covered:

1. Create custom BOR object with the events, Start and Stop event
2. Create a workflow for the error handling, like generating a notification whenever an error occurred in the Inbound Idoc.
3. Creation of Function Module and attachment with the Process Code
4. Create the settings for the Inbound Process of the Idoc through the Process Code.
