ESS - Implementation of BADI PT_GEN_REQ
I have implemented BADI PT_GEN_REQ for a user defined suggetion of the next processor (method FIND_RESP_AND_DEFAULT_NEXT_PRC). This part works fine. When the user overwrite the suggestion with his own value i want to check his input. But the method CHECK_SELECTED_NEXT_PROCESSOR has no interface. How could i point out to the system, that a user defined input is incorrect.
