Warning

UBL-CR-459: Payment terms must not carry an amount

In short

Warning: worth checking.

UBL-CR-459 warns that your UBL invoice or credit note includes cbc:Amount within the payment terms. Remove that particular amount element from the XML, not the invoice's amount due, and recheck the file.

On this page

What it means

This rule checks that cac:PaymentTerms contains no cbc:Amount element. It does not target the amount due (BT-115) in the invoice totals.

Why it matters

EN 16931 does not use this amount element within UBL payment terms. The invoice's overall amount due (BT-115) is a separate field.

How to fix it

Remove cbc:Amount only from cac:PaymentTerms. If it describes an agreed instalment, state the payment schedule in cbc:Note (BT-20). Do not change the invoice totals or due date (BT-9) merely to clear this warning. Recheck the file.
