Connections to Non-SAP Systems
ALE is not limited to using for coupling SAP systems only, but can also be used as a general technical basis for connecting R/3 Systems to non-SAP systems.
By using IDocs as universal information containers, ALE can reduce the number of different application interfaces to a single interface that either sends IDocs from an R/3 System or receives IDocs at the other end.
