Warning

UBL-CR-454: Payment terms must not carry a prepaid payment reference

In short

Warning: worth checking.

UBL-CR-454 warns that your UBL invoice or credit note includes a prepaid payment reference (cbc:PrepaidPaymentReferenceID) within the payment terms. Remove that reference element from the XML and recheck the file.

On this page

What it means

This rule checks that cac:PaymentTerms contains no cbc:PrepaidPaymentReferenceID element. It does not calculate the paid amount (BT-113) or the amount due (BT-115).

Why it matters

EN 16931 does not use this prepaid payment reference element within UBL payment terms.

How to fix it

Remove cbc:PrepaidPaymentReferenceID from cac:PaymentTerms. Do not enter a prepayment again merely to clear this warning if it is already included in the paid amount (BT-113). Check any changes to the payment totals separately, then recheck the file.
