Application Link Enabling (ALE)


Application Link Enabling ensures a distributed but integrated SAP installation. It comprises the controlled exchange of business messages and consistent data management in loosely-linked SAP application systems.


Applications are integrated by synchronous and asynchronous communication, not in a central database.

Application Link Enabling has three layers:

·         Application services

·         Distribution services

·         Communication services
