What it means
The rule looks inside the payment terms block (cac:PaymentTerms) of the invoice or credit note and warns when it holds a PaymentDueDate element. EN 16931 has one due date for the whole invoice (BT-9) and payment terms text (BT-20). It has no due date inside the payment terms block itself. This is a warning.
Why it matters
EN 16931 uses the due date field (BT-9), not a date element inside cac:PaymentTerms.
How to fix it
Remove cbc:PaymentDueDate from cac:PaymentTerms. If you need to give a due date (BT-9), put it in cbc:DueDate on an invoice, or in cbc:PaymentDueDate inside cac:PaymentMeans on a credit note. Check the corrected file again.
