Can a non PO invoice from iSupplier portal can be matched to a PO later ?

Hi,

Many of our users do not create purchase orders.

They just place orders over telephone or email.

The invoice comes first then based on that users raise a purchase order.

We are on R12.2.4 and implementing iSupplier portal now.

If the supplier creates a non po invoice on 1st August in iSupplier portal.

The user will be informed about the same and then the user will create a PO on 10 august. ( invoice predates and precedes PO )

Now Can payables team match invoice to the PO ?

Can this work ?

Please advice.

thx,

Daniela
