Hi
Default the DEBMAS processing function module is MASTERIDOC_CREATE_SMD_DEBMAS. This is configured in view V_TBDME. This function module does not read addresses.
We created a customer function module Z_MASTERIDOC_CREATE_SMD_DEBMAS and assigned it to the required customer master data IDOC message type. The additional coding is limited. It is reading change pointers for addresses (object ADRESSE) and gets the linked customer with function module ADDR_REFERENCE_GET and then calls the standard processing function module MASTERIDOC_CREATE_REQ_DEBMAS.
