ALE is an SAP proprietary technology that enables data communication between SAP systems. ALE also enables data communication between SAP and external systems.

You can configure outbound mappings to read IDocs from SAP and inbound mappings to write IDocs to SAP.

You can also overwrite the source and target connections at run time with values specified in a parameter file. To overwrite the source and target connections at run time, you need to parameterize both the connections and the objects in a mapping.

In advanced mode, the Mapping Designer updates the mapping canvas to include transformations and functions that enable advanced functionality.

To configure an outbound mapping to read IDocs from SAP, perform the following tasks:

Configure an IDoc mapplet using the
Mapplet - SAP IDoc
asset from
Data Integration
. Verify that you selected the segments and groups you want to include in the IDoc. In addition, select the
IDoc Interpreter
transformation.
Configure an outbound mapping using the generated IDoc mapplet. Add a Source transformation to read data from the SAP system, add the generated IDoc mapplet, and add a Target transformation to write the IDoc in the target object.

To configure an inbound mapping to write IDocs to SAP, perform the following tasks:

Create an IDoc mapplet using the
Mapplet - SAP IDoc
asset from
Data Integration
. Verify that you selected the segments and groups you want to include in the IDoc. In addition, select the
IDoc Prepare
transformation.
Do not configure multiple IDoc Prepare transformations for an IDoc mapplet in an inbound mapping on Linux. Otherwise, the mapping fails with the DTM error.
Configure an inbound mapping using the generated IDoc mapplet. Add a Source transformation to read data from the source system, add the generated IDoc mapplet, and add a Target transformation to write the IDoc to the SAP system.
