When an IDoc first comes into the SAP ALE layer, what is the FIRST program/function module that is executed?
Please, I am NOT looking for the function module triggered by the process code. There must be a generic program/function module that is executed first which then determines which function module is needed to actually process the data.
I guess I am looking for the program/function module that stores the incoming IDoc in the IDoc tables such as EDIDC, EDID4, etc.
Thanks.
