BU recognition invoice scanning PO matched invoice

BU recognition invoice scanning

Content

Does anyone know how the BU is exactly defaulted for PO matched invoices by the Oracle imaging solution? The documentation states that the BU is recognised by the Purchase order, but it's not saying it's based on the Bill to BU.

Our situation is that we have a new Purchasing BU to be implemented, but the BU which is going to pay the invoice is a different BU. So to be clear on the PO, the REQ BU = X, Proc. BU = X, Bill to BU = Y and the invoice needs to be paid by BU Y. What happens if the invoice is processed by the imaging solution. I expect the BU is in this case defaulted to the BU Y.
