Bapi_PO_Create1 problem with POPARTNR
I am having problems now with doing a PO create from PR. The BAPI was working but now i have to overide the vendor for the partner function "Invoice Presented by" (PI). so i am going to try and use the table POPARTNER , but i get the error "Please enter a partner role ". i pass it the partner number which in this case is the vendor.
does anyone have any idea as to what is going on. thanks alot.
