fatal UBL auto-fix
A Peppol BIS Billing 3.0 rule (OpenPeppol): an extra requirement for invoices sent over the Peppol network, for example electronic addresses (BT-34, BT-49), the business process (BT-23) or code values. This is an error: the invoice is rejected until it is fixed.
Automatic fix: 9 € per file (excl. VAT where applicable). An unknown business process identifier is replaced by the Peppol billing process (parameter 01/02). The result page shows which errors the repair removes and whether the corrected file then passes — before you pay. Many files? Pilot and Repair API.
[PEPPOL-EN16931-R007]-Business process MUST have an approved identifier.
An unknown business process identifier is replaced by the Peppol billing process (parameter 01/02).
This rule is in the deterministic set of our repair engine (UBL 2.1; measured 2026-10-23: XRechnung 15 broken test invoices accepted after repair, 45 valid invoices unchanged; Peppol BIS Billing 3: 10 official examples unchanged, 40 mutated invoices: 36 accepted after repair, 4 rejected as expected — one documented limit, two with the repair parameter switched off, one where no address could be derived; profile conversion of 33 XRechnung test invoices to Peppol: 30 accepted). For UN/CEFACT CII (Factur-X / ZUGFeRD EN 16931 XML, XRechnung CII) the engine repairs the totals chain, VAT breakdown, rounding, decimals and element order (measured 2026-10-24: 53 valid CEN and XRechnung CII invoices unchanged; 28 broken invoices: 27 accepted after repair, 1 rejected as expected because a VAT exemption reason cannot be derived). Single files: 9 € on the result page; many files: the Repair API — see Pricing.
