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 non-compliant and will be rejected by Peppol access points and national validation services. The sending system receives a rejection response and the invoice does not reach 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. Invoices that trigger this rule are rejected at the access point and never reach the recipient. In Peppol networks, this means your sending system receives an MLR (Message Level Response) with a rejection status. The invoice must be corrected and re-sent, adding delay to your payment cycle.
