Can anybody tell me what is the function module that can change the Business Partner number, i.e., can change an existing business partner no. by taking an existing and new business partner as input and changes the existing one to the new one. I have seen BAPI_BUSINESS_PARTNER_CHANGE and BAPI_BUSINESS_PARTNER_MODIFY but they don't change the BP no.
I have a file in which I am having a list of old BPno.s as well as the new BP no.s.
I need to replace the old BP no.s with the new one that is there in the file.
Thanks in advance,
