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 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: //cac:PartyLegalEntity/cbc:CompanyID with schemeID=0037
Why This Error Matters
Finnish business identification required.
FI-R-001 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.
