SAP EDI Process and IDOC Configuration
SAP EDI Process
In any SAP EDI Process a Sub System is required. Basically an EDI Subsystem does the conversion of SAP IDOCs to to EDI Format and Vice Versa. An EDI subsystem is a thirdparty systems and deals with standards that are most current.
Thus as mentioned above the EDI SubSystem acts like a translator. SAP does certify some EDI subsystems and this is based on the version of SAP.
Basically the SAP EDI process is comprised of
InBound Process
OutBound Process
The OutBound Document is Created. This could be a Sales Order or a Purchase Order or an Invoice. The process of creating the document is no different than the normal way. But prior to this IDOC configuration is made so that on the document is saved an IDOC is generated. The document is saved in the SAP tables in the usual way but in addition to that an IDOC with the same data is also generated and saved.
You can view this IDOC using the appropriate transactions. Example WE05 — IDOC List WE02 Display IDOC. Once the IDOC is generated it is transferred to the operating system level for the EDI system to pick it up. Further to this the IDOC is converted to the EDI standards and the IDOC is then transferred to the desired Partner. The status of this transaction is sent back to SAP
