Built into SAP’s applications are interfaces to EDI messages.SAP provides an open, common interface to EDI translators / subsystems (XA-EDI). EDI subsystems assume responsibility for all EDI-oriented tasks:
From the SAP side, the EDI interface is based on IDoc technology, which is independent of EDI standards but modelled against the EDIFACT standard. All data is transferred in files between the SAP System and the EDI subsystem. A Synchronous Remote Function Call (RFC) is implemented to transfer a file between the two systems. The following data can be transferred using the EDI interface:
Certification of an EDI subsystem involves technical testing of the interface between the SAP System and the EDI subsystem. The transfer of outbound IDocs, inbound IDocs and status reports is tested. The test is carried out using the UN/EDIFACT standard for EDI. The following messages may be used:
The STATUS Idoc needs to be returned to the SAP system to report on the statuses shown in the below diagram. 05,06, 07, 08, 11, 12, 16 and 17.
