What is FI-R-001?
FI-R-001 is a fatal validation rule defined in the peppol-bis-3 specification (FIN national rules). It validates the CompanyID with schemeID=0037 element under PartyLegalEntity in the UBL invoice XML.
When this rule fires, the invoice is rejected by Peppol access points and never reaches the buyer.
