What is FR-R-009?
FR-R-009 is a warning validation rule defined in the factur-x specification (FRA national rules). It validates the CompanyLegalForm element under PartyLegalEntity 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: XPath: //cac:PartyLegalEntity/cbc:CompanyLegalForm
Why This Error Matters
French commercial law requires RCS on business documents.
FR-R-009 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.
