What is BR-CO-25?
BR-CO-25 is a warning validation rule defined in the EN 16931 specification. It validates the ID element under Invoice > InvoiceLine 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: /Invoice/cac:InvoiceLine/cbc:ID
Why This Error Matters
Invoice rejected. Buyers need to know when payment is expected.
BR-CO-25 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.
