When matching a PO to an Invoice, can you change the Ship_To location?

We recently started using More4Apps AP Invoice Wizard to match POs to invoices in Oracle. During testing we noticed that if we attempt to change the Ship_To location when matching a PO to an Invoice, we receive an error in the Wizard.

For example, the PO has a Ship_To location of 'US BOSTON' and in the AP Invoice Wizard and we attempted to change it to 'US NEW YORK' within the AP Invoice Wizard.

The invoice validated OK in the Wizard, but when we ran the 'Payables Open Interface Import' program (via the AP Invoice Wizard) to send the invoice data to the AP_INVOICES_INTERFACE table we get this error message: "PO line location ID and PO shipment number do not match"
