In one SAP system, when user creates one PO, the system will send out one IDOC. the IDOC message type is ORDERS and basic type is ORDERS05.
In the WE02, I find the E1EDK05-KRATE is 3.0.
I want to know, is the mapping between IDOC field and Po data preconfigured, or hard-coded in the system by coding?
If it's preconfigured, where can I find the mapping between IDOC and PO?
