What does UBL-CR-412 mean? A UBL invoice should not include the PaymentMeans PaymentDueDate

Why did my invoice fail UBL-CR-412?

The UBL element cac:PaymentMeans/cbc:PaymentDueDate should not be used in an EN 16931 invoice. The payment due date (BT-9) is carried once at document level as cbc:DueDate, not inside PaymentMeans, to avoid duplicated and possibly conflicting dates.

Official rule text

A UBL invoice should not include the PaymentMeans PaymentDueDate

Common causes

Mapping the due date into both the document header and PaymentMeans
Following plain UBL 2.1 examples where PaymentDueDate is valid
ERP export that attaches the due date to the payment record

How do I fix it?

<cbc:DueDate>2026-08-17</cbc:DueDate>
<!-- at Invoice root level, not inside cac:PaymentMeans -->
