Direct Outbound Processing: Technical Implementation for ALE

The way in which the IDoc is generated depends on the respective application. The following is an example of an ALE scenario in which a function module is responsible for generating the IDocs.

The function module is called in the application transaction. The function module generates a so-called master IDoc, which is transferred to the administration module MASTER_IDOC_DISTRIBUTE, which checks the control record and then calls the function module COMMUNICATION_IDOC_CREATE. This module "filters" the master IDoc (that is to say removes any data which is not required for communication). This "filtered" IDoc is referred to as the communication IDoc and is forwarded for further processing to the function module EDI_OUTPUT_NEW by MASTER_IDOC_DISTRIBUTE.
