System Response

If you take the first item without reference to the purchase order
(direct posting to G/L account or material) and the terms of payment are
empty, the terms of payment key from the accounting view of the supplier
master view is automatically inserted in the terms of payment field.
Automatic insertion only occurs in the case of the transactions
"invoice" or "subsequent debit".

How to fix this error?

Please check the terms of payment on the "Payment" tab page with those
shown in the invoice.
