What it means
The despatch advice reference (BT-16) points at the despatch advice, the document that lists what was sent. In a UBL invoice or credit note it is cac:DespatchDocumentReference. This rule checks that the block does not contain text naming the type of document (cbc:DocumentType).
Why it matters
EN 16931 does not use document type text inside the despatch advice reference.
How to fix it
Remove the document type text from the despatch advice reference. If the software adds the text itself, ask its supplier for an export that leaves it out. If you build the XML yourself, delete cbc:DocumentType from cac:DespatchDocumentReference. Then check the file again.
