Official rule text
An Invoice shall contain the Seller name (BT-27).
What this error means
The invoice must contain the Seller name (BT-27) - the legal name of the supplier, under cac:AccountingSupplierParty/cac:Party/cac:PartyLegalEntity/cbc:RegistrationName.
How to fix it
- Add the seller's registered legal name in
cbc:RegistrationName. - The trading name (BT-28) does not satisfy this rule - both may be present, but the legal name is the mandatory one.
