What is BR-IT-01?
BR-IT-01 is a fatal validation rule defined in the peppol-bis-3 specification (ITA national rules). It validates the CompanyID element under Party > PartyTaxScheme in the UBL invoice XML.
When this rule fires, the invoice is rejected by Peppol access points and never reaches the buyer.

Why This Error Matters
SDI (Sistema di Interscambio) requires valid tax identifiers for invoice routing and VAT reporting.
BR-IT-01 is a hard failure — the invoice must be corrected and re-sent before it can reach the recipient.
