What it means
The rule checks that the delivery section of a UBL file (cac:Delivery) has no tracking identifier (cbc:TrackingID). In UBL that field holds the number used to follow a shipment with a carrier. EN 16931 has no business term for it.
Why it matters
EN 16931 does not use a separate tracking-number field in the delivery section.
How to fix it
Clear the tracking number from the delivery data in your invoicing software and export again. If the buyer wants it, add it to the invoice note (BT-22) as plain text, or send it in your shipping confirmation. If you build the XML yourself, delete the cbc:TrackingID that sits directly under cac:Delivery.
