In any SAP EDI Process a Sub System is required. Basically an EDI Subsystem does the conversion of SAP IDOCs to to EDI fromat 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
OutBound Process 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.
Always use Pretty Printer and Extended Program Check before releasing the code.
Do not leave unused code in the program. Comment the code thoroughly. Align the comments and the Code. Follow the SAP Standards and SAP Best Practices guidelines. It’s a good practice to take a dump of the code on your local drive.
