What is CZ-R-002?
CZ-R-002 is a warning validation rule defined in the ubl-2.1 specification (CZE national rules). It validates the CompanyID 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:CompanyID
Why This Error Matters
IČO provides company identification.
CZ-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.
