What is UBL-CR-154?
UBL-CR-154 is a fatal validation rule defined in the UBL 2.1 specification. It validates the BuildingName element under Party > PostalAddress in the UBL invoice XML.
When this rule fires, the invoice is rejected by Peppol access points and never reaches the buyer.
Target path: /Invoice/cac:AccountingSupplierParty/cac:Party/cac:PostalAddress/cbc:BuildingName
Why This Error Matters
Invoice will be rejected by PEPPOL/EN16931 validators. Safe to remove - these elements are explicitly prohibited in EN16931 and contain no required business data.
UBL-CR-154 is a hard failure — the invoice must be corrected and re-sent before it can reach the recipient.
Invoice Navigator can automatically correct this error in your pipeline. The fix is applied with full audit evidence, so your compliance trail remains intact.

How to Fix It
Locate the disallowed element
Open your invoice XML and find cbc:BuildingName at /Invoice/cac:AccountingSupplierParty/cac:Party/cac:PostalAddress/cbc:BuildingName. This element is not permitted in the target e-invoice profile and triggers UBL-CR-154.
Remove cbc:BuildingName
Delete the entire cbc:BuildingName block and its child elements. Invoice Navigator automatically removes the disallowed `cbc:BuildingName` element from your Invoice.
Re-validate your invoice
Upload the corrected invoice to confirm UBL-CR-154 is resolved. If your software consistently adds this element, contact your vendor about their e-invoice export settings.
