What it means
The check looks at a UBL invoice and warns when cac:PaymentMeans contains a cbc:PaymentDueDate. The due date (BT-9) of an invoice has its own place at the top of the document, cbc:DueDate. Credit notes are exempt from this check.
Why it matters
For a UBL invoice, the due date (BT-9) belongs in cbc:DueDate directly under the root element, not in cac:PaymentMeans/cbc:PaymentDueDate. The rule explicitly exempts credit notes.
How to fix it
For a UBL invoice, put the due date (BT-9) in cbc:DueDate directly under the root element and delete cbc:PaymentDueDate from cac:PaymentMeans. If the same date is already in both places, delete only the one in the payment means. Export the corrected invoice and check it again.
