Engine Classification

Financial or legal field · Modification blocked by policy

Reason: SAF-T (PT) compliance requires invoices to be structured according to the Portuguese Standard Audit File for Tax format. This cannot be achieved by modifying individual fields. Ensure your invoicing software is SAF-T (PT) compliant for proper tax reporting to Autoridade Tributária.

What is PT-R-003?

PT-R-003 is a warning validation rule defined in the ubl-2.1 specification (PRT national rules). It validates the SAF-T PT export requirement 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: SAF-T PT export requirement

This error requires manual correction — financial fields are protected by policy.

Why This Error Matters

Portuguese companies must submit SAF-T files monthly.

PT-R-003 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.
