Overview of the ALE module

This chapter describes the ALE (Application Link Enabling) Module of the IBM WebSphere Business Integration Adapter for mySAP.com (SAP R/3 Version 4.x) The ALE Module allows an integration broker to send business objects to and receive events from SAP R/3 application version 3.1H or 3.1I.

ALE is an SAP interface that allows systems to communicate asynchronously with the R/3 system:

Important:
In releases of the connector prior to version 4.8.x, the connector used collaborations, business objects, and maps to store Transaction IDs (TIDs) and their status in the repository, and used the local file system to store IDoc data. Version 4.8.x of the connector replaces the previous management of TIDs and IDoc data with the use of MQSeries queues.
Note:
Because the ALE Module uses asynchronous communication, it cannot be used when cross-referencing is required.
