BR-08
The seller postal address group (BG-5) is missing entirely.
ErrorEN 16931UBLCII
Why it happens
No address block was produced for the supplier. Even a minimal address group is mandatory.
How to fix it
Add cac:AccountingSupplierParty/cac:Party/cac:PostalAddress (UBL) or ram:SellerTradeParty/ram:PostalTradeAddress (CII). At minimum it must carry the country code (BT-40); most profiles also require city and post code.
