Implementing an ALE interface

About this task

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.

To implement an ALE Interface:


  1. Enter transaction code /nWE63 in the SAP application to select IDoc(s) and download the metadata.
  2. Use Connections and Actions to generate the schema.
  3. Use the Design Server to create the map.
  4. Configure the SAP R/3 system for inbound or outbound processing. See Configuring the SAP R/3 system in and Setting up an RFC destination.
