Accounts Payable - Correcting Invoice Errors

        We seem to be unable with ACP500 to correct for vendor invoice
errors, and am wondering how others handle the situation.

        If a vendor invoices us for too large a quantity, Accounts
Payable may pay the invoice if a subsequent receipt has been entered.

        When the vendor issues a credit, we see no way to enter that to
reduce the quantity costed so that subsequent receipts can be accurately
paid. Is there a way to do that?

        We're on 8.0.
