What does UBL-CR-463 mean? A UBL invoice should not include the PaymentTerms PaymentDueDate

Why did my invoice fail UBL-CR-463?

EN 16931 defines a fixed semantic model, and any UBL element outside that model must not be used. This rule flags the cac:PaymentTerms/cbc:PaymentDueDate element, which has no corresponding business term in EN 16931, so a compliant invoice should not include it. Within cac:PaymentTerms, EN 16931 supports only a textual description of the payment terms (cbc:Note, BT-20); all structured payment-terms sub-elements are outside the model. The payment due date (BT-9) is carried at document level in cbc:DueDate, not inside PaymentTerms.

Official rule text

A UBL invoice should not include the PaymentTerms PaymentDueDate

Common causes

Due date mapped into PaymentTerms instead of the document-level cbc:DueDate (BT-9)
A mapping template copies every source field into UBL without filtering to the EN 16931 element list
Reusing an invoice template from a non-EN 16931 UBL profile that populated this element

How do I fix it?

<!-- document level, not inside cac:PaymentTerms -->
<cbc:DueDate>2026-08-17</cbc:DueDate>
