Application Link Enabling
Application Link Enabling (ALE) supports the distribution of business functions and processes across loosely coupled R/3 Systems. Connections from R/2 and non-SAP systems are supported.
Distributing business applications and at the same time ensuring data consistency is practical because:
ALE supports the configuration and operation of distributed applications. ALE supports the configuration and operation of distributed applications. ALE handles the Message Exchange Between Distributed Applications across loosely coupled R/3-System, ensuring that data is always consistent.
Applications are integrated using a local database rather than a central one. There is no data retention. ALE ensures data is distributed and coordinated using asynchronous communication. ALE uses synchronous connections for reading data.
ALE has functions for controlling messages flows (Audit) and for eliminating malfunctions.
