What is IT-R-007?

IT-R-007 is a fatal validation rule defined in the ubl-2.1 specification (ITA national rules). It validates the Party note or extension element under AccountingSupplierParty 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.

Why This Error Matters

SDI requires regime fiscale for all Italian sellers.

IT-R-007 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.
