What it means
This rule checks the delivery address (BG-15), the place where the goods or services were delivered. It looks for a PO box element (cbc:Postbox inside cac:Delivery/cac:DeliveryLocation/cac:Address) and warns if there is one. The same check applies to a credit note. EN 16931 has no separate field for a PO box, so the element is not part of the invoice model.
Why it matters
EN 16931 does not use a separate PO box element in the delivery address.
How to fix it
Check whether your invoicing software exports the delivery address PO box in its own element. Move the detail into the street line or an extra address line, or leave it out if the buyer does not need it. If you build the XML yourself, delete cbc:Postbox from cac:Delivery/cac:DeliveryLocation/cac:Address and, if you keep the detail, write it into cbc:StreetName or cbc:AdditionalStreetName in the same address. Recheck the corrected file.
