What it means
For each invoice line (BG-25), the rule checks that ram:AdditionalReferenceReferencedDocument is absent from ram:SpecifiedTradeProduct (BG-31). References in other locations, including the invoice line object identifier (BT-128), are not tested by this rule.
Why it matters
The EN 16931 CII mapping does not use this additional-document-reference element within product details. The invoice line object identifier (BT-128) identifies the object being invoiced; it is not a general document reference or the line's own identifier.
How to fix it
Remove ram:AdditionalReferenceReferencedDocument from the line's product details. If you need to include the document, add it as an invoice-level attachment (BG-24). Use the invoice line object identifier (BT-128) only if the value identifies the object being invoiced. Export the corrected file and check it again.
