What is BR-07?
BR-07 is a fatal validation rule defined in the EN 16931 specification. It validates the PostalAddress element under AccountingSupplierParty > Party in the UBL invoice XML.
When this rule fires, the invoice is rejected by Peppol access points and never reaches the buyer.
Target path: XPath: /Invoice/cac:AccountingSupplierParty/cac:Party/cac:PostalAddress
Why This Error Matters
Invoice rejected. The recipient cannot verify they are the intended buyer, and the invoice is legally invalid.
BR-07 is a hard failure — the invoice must be corrected and re-sent before it can reach the recipient.
The buyer name is required for proper invoice routing and payment processing in the Peppol network. Without it, the invoice cannot be matched to the correct customer.
