Engine Classification

Reason: Finnish domestic B2B invoices often require Finvoice format instead of UBL/Peppol. This requires generating the invoice in Finvoice XML format from your invoicing software. Contact your software vendor for Finvoice support.
What is FI-R-002?
FI-R-002 is a warning validation rule defined in the finvoice specification (FIN national rules). It validates the Finvoice 3.0 schema compliance element in the UBL invoice XML.
This is a soft validation failure. The invoice may pass initial transmission, but non-compliant values in this field can cause problems during tax audits, buyer-side processing, or downstream VAT reconciliation.
Target path: Finvoice 3.0 schema compliance
Why This Error Matters
Finvoice integrates with Finnish banking.
FI-R-002 is a soft failure. The invoice may pass initial validation, but the non-compliant field can cause issues at the receiving end — tax authorities may flag it during audits, buyer ERP systems may fail to process it, or VAT reconciliation may produce mismatches. Fixing warnings before they accumulate prevents larger compliance gaps.
