Hi Sam,

Adagio requires different new documents to have unique numbers. This includes purchase order numbers. You will not be able to receive goods against the same PO multiple times. As would be expected.

You can create Template purchase orders to be copied each week for new POs. And if this is just a matter of the supplier seeing the same PO number on the form they receive, you could create a special PO specification that puts say a Reference or Comment value in the box with the PO label, so Adagio continues to store it's separate PO numbers as necessary for internal use, but the supplier sees their special number.

As for matching up future invoices, they must have a process in place for doing this already against the same PO number, such as the date or something else identifying?. In Adagio PO, you would match invoice the receipt number (vendor document number) which might come from the packing slip.
