When we enter a purchase invoice, and the document amount including VAT that we fill in the header of the invoice does not match the total amount including VAT from the lines, we receive an error message when we want to 'post' te invoice. Subsequently, we adjust the invoice, after which we can proceed with the booking.
Nowadays, we utilize an approval request before being able to process invoices for payment. We would like to receive this error message when requesting approval for the purchase invoice. What currently occurs more often is that the amounts do not match, we request approval, when the invoice is released, we cannot book it because the invoice amount does not match. Subsequently, we have to adjust the amounts and request approval again.
