What is BR-IT-03?
BR-IT-03 is a fatal validation rule defined in the peppol-bis-3 specification (ITA national rules). It validates the Invoice extension for FatturaPA 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: /Invoice extension for FatturaPA
Why This Error Matters
SDI requires Regime Fiscale to apply correct tax rules and reporting.
BR-IT-03 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.
