Priority between purchasing groups

[#1]

Hi guys,

I was wondering how I can find out what purchasing group has the highest priority when a purchase order has been created for a material and a vendor assigned to different purchasing groups.

thanks in advance

The assignment happens with automatic PR creation from MRP run

The purchasing group from material has priority

The purchasing group from vendor master is only taken if you have no purchasing group maintained in material master.

each buyer is usually a purchasing group assigned and he is often even restricted via authorization to this purchasing group.

this means the buyer starts the activities in ME57 looking for requisition assigned to his purchasing group. He assigns then the source of supply, if not already automatically done from MRP run, and processes the requisition further into a PO.
