What does UBL-CR-470 mean? A UBL invoice should not include the PrepaidPayment

Why did my invoice fail UBL-CR-470?

EN 16931 defines a fixed semantic model, and any UBL element outside that model must not be used. This rule flags the cac:PrepaidPayment element, which has no corresponding business term in EN 16931, so a compliant invoice should not include it. EN 16931 carries the prepaid amount as a single total (BT-113) in cac:LegalMonetaryTotal/cbc:PrepaidAmount; a structured list of individual prepayments has no business terms in the model.

Official rule text

A UBL invoice should not include the PrepaidPayment

Common causes

Individual prepayment records exported instead of aggregating them into cbc:PrepaidAmount (BT-113)
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?

<cac:LegalMonetaryTotal>
  <!-- ... -->
  <cbc:PrepaidAmount currencyID="EUR">100.00</cbc:PrepaidAmount>
  <cbc:PayableAmount currencyID="EUR">1100.00</cbc:PayableAmount>
</cac:LegalMonetaryTotal>
