What is UBL-CR-295?

When this rule fires, the invoice is rejected by Peppol access points and never reaches the buyer.

Target path: /Invoice/cac:SellerSupplierParty

Fix this error

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-295 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 cac:SellerSupplierParty at /Invoice/cac:SellerSupplierParty. This element is not permitted in the target e-invoice profile and triggers UBL-CR-295.

Remove cac:SellerSupplierParty

Delete the entire cac:SellerSupplierParty block and its child elements. Invoice Navigator automatically removes the disallowed `cac:SellerSupplierParty` element from your Invoice.

Re-validate your invoice

Upload the corrected invoice to confirm UBL-CR-295 is resolved. If your software consistently adds this element, contact your vendor about their e-invoice export settings.
