If SRM users entered preferred vendor for only one line item in a shopping cart which has more than one line items, I tried to populate the preferred vendor for the rest of line items.
I tried to use BADI BBP_DOC_CHANGE_BADI to insert the preferred vendor data into ET_PARTNER table, but I dont know how SAP populates the PARTNER_GUID in that table. When I debugged, I can tell it was not from tables VENMAP & BUT000. It was unique in each line in imported table IT_PARTNER.
Do I need to populates the PARTNER_GUID for my records?
Or can I just overwrite one of the record in ET_PARTNER table?
