What is BR-FR-06?
BR-FR-06 is a fatal validation rule defined in the factur-x specification (FRA national rules). It validates the XPath: Specific Chorus Pro extension fields element 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: Specific Chorus Pro extension fields
Why This Error Matters
Chorus Pro routes invoices based on service code for French public entities.
BR-FR-06 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.
