Inbound Processing: Technical Implementation
The IDocs are received by various function modules or reports, depending on the inbound port. The table below provides an overview and shows the interface (reference fields or structures, import parameters). Table parameters (call by reference) are marked separately.
The function module IDOC_INBOUND_WRITE_TO_DB is responsible for saving the data to the database. The function module also uses the process code to determine whether processing by ALE services is to take place.
The IDocs are then transferred to the application function module by IDOC_START_INBOUND. In all cases, except those in which the IDocs are transferred using the tRFC port, an event is triggered which, in turn, starts task TS30200090.
IDOC_START_INBOUND starts a workflow or a function module. This decision is also controlled using the inbound process code.
