I have a change requirement for a working print preview using ZMEDRUCK for transaction ME21N.
Users can choose from multiple ordering addresses for vendors - they want to see the ordering address vendor they have selected (shown on the ME21N screen header under the partners tab) on the print preview of the Purchase Order.
IF the PO has been saved this is not a problem, I can pick the ordering address vendor number from EKPA based on the Purchase Order Number.
BUT before the PO is saved this record doesn't exist yet. Does anyone know what fields/process should be used to extract the ordering address vendor number to add to the print preview BEFORE the PO is saved?
