What is BR-54?
BR-54 is a fatal validation rule defined in the EN 16931 specification. It validates the ram:BillingSpecifiedPeriod 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: ram:SpecifiedLineTradeSettlement/ram:BillingSpecifiedPeriod
Why This Error Matters
Invoice rejected. Product attributes must have both name and value to be meaningful.
BR-54 is a hard failure — the invoice must be corrected and re-sent before it can reach the recipient.
