This information field shows the difference between the invoice amount and the order amount including VAT. The difference can be max +/- 1,00 in order for the invoice to be final coded and approved for payment when you link the invoice. If the difference is < 1, it will be coded as round-off. If the invoice is linked anyway despite the difference, the system will open the coding box so that you can manually code the difference. If a difference appears in this field when you link orders, you will see a dialog box that informs you that you cannot link or final code the invoice due to the difference.
