What is BR-CO-06?
BR-CO-06 is a fatal validation rule defined in the EN 16931 specification. It validates the AllowanceChargeReason element in the UBL invoice XML.
When this rule fires, the invoice is rejected by Peppol access points and never reaches the buyer.
Target path: //cac:AllowanceCharge[cbc:ChargeIndicator=true]/cbc:AllowanceChargeReason
Why This Error Matters
Semantic consistency between reason codes and text prevents ambiguity. When processing systems see code FC, they expect freight-related text. Mismatches can cause confusion in automated processing and reporting.
BR-CO-06 is a hard failure — the invoice must be corrected and re-sent before it can reach the recipient.
Validators reject invoices where the surcharge reason code and text contradict each other. Peppol access points and tax authorities may flag this as non-compliant.
Invoice Navigator can automatically correct this error in your pipeline. The fix is applied with full audit evidence, so your compliance trail remains intact.
