I have a requirement in which I need to create the customer master through IDOC. I am using DEBMAS basic type for that. In its functionality, I need to assign different partner functions to it.
When I create customer without giving any partner details, 4 entries get created by default with partner functions as BP, SP, PY, SH and KUNN2 value as INTERNAL or the same customer number which is getting created. But I want that the customer number provided by me should be assigned as partner function. Is there any way to change the default entry which is getting created so that I can replace the INTERNAL customer number with the one provided by me.
I identified the segment as E1KNVPM in it at hierarchy level 3. I passed the partner function in the PARVW field of it and provided the customer number which I want to assign as partner function in the KUNN2 field. But I am getting error Customer INTERNAL already exists for function <Partner function>.
Am I missing something. Any msgfn or any other input.
Please help me on this.
