What is BR-DEC-01?

BR-DEC-01 is a fatal validation rule defined in the EN 16931 specification. It validates the Amount element in the UBL invoice XML.

When this rule fires, the invoice is non-compliant and will be rejected by Peppol access points and national validation services. The sending system receives a rejection response and the invoice does not reach the buyer.

Target path: //cac:AllowanceCharge[cbc:ChargeIndicator='false']/cbc:Amount

Why This Error Matters

Invoice will be rejected by validation. Financial systems require consistent 2-decimal precision for proper accounting and reconciliation.

BR-DEC-01 is a hard failure. Invoices that trigger this rule are rejected at the access point and never reach the recipient. In Peppol networks, this means your sending system receives an MLR (Message Level Response) with a rejection status. The invoice must be corrected and re-sent, adding delay to your payment cycle.

Invoice Navigator can automatically correct this error in your pipeline. The fix is applied with full audit evidence, so your compliance trail remains intact.
