Overview

The SAP R/3 ALE adapter provides facility to send and receive IDocs from SAP R/3 system. The SAP Application Link Enabling (ALE) technology enables data communication between two or more SAP R/3 systems and/or SAP R/3 and external (for example, legacy) systems. The SAP R/3 system must be configured to send and receive IDocs.

IDoc stands for Intermediate Document, is simply a data container used to exchange information between any two processes that can understand the syntax and semantics of the data. In other words, an IDoc is like a data file with a specified format which is exchanged between two systems which knows how to interpret that data.

When we execute an outbound ALE or EDI Process, an IDoc is created.
