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 rejected by Peppol access points and never reaches the buyer.
