BR-06
Error (blocking) EN 16931 (UBL)EN 16931 (CII)
Official rule text
[BR-06]-An Invoice shall contain the Seller name (BT-27).
What it means
The seller's legal name (BT-27) is mandatory. In the UBL binding the check targets cac:AccountingSupplierParty/cac:Party/cac:PartyLegalEntity/cbc:RegistrationName specifically - supplying only cac:PartyName/cbc:Name (the trading name, BT-28) does not satisfy it, and that is the most common reason this rule fires.
How to fix it
Add cbc:RegistrationName under the supplier's cac:PartyLegalEntity (UBL) or fill ram:SellerTradeParty/ram:Name (CII) with the seller's registered legal name (BT-27).
Business terms involved: BT-27
🇫🇷 En français
La raison sociale du vendeur (BT-27) est obligatoire. En UBL, le contrôle vise précisément cac:AccountingSupplierParty/cac:Party/cac:PartyLegalEntity/cbc:RegistrationName : ne fournir que cac:PartyName/cbc:Name (le nom commercial, BT-28) ne suffit pas, et c'est la cause d'échec la plus fréquente.
Correction : Ajoutez cbc:RegistrationName sous le cac:PartyLegalEntity du vendeur (UBL) ou renseignez ram:SellerTradeParty/ram:Name (CII) avec la raison sociale (BT-27).
