Warning

UBL-CR-242: Leave the buyer's registration expiry date out

In short

Warning: worth checking.

UBL-CR-242 means the buyer's details include the date their company registration expires (RegistrationExpirationDate), which EN 16931 does not use. Remove that element from the buyer's legal entity block.

On this page

What it means

This rule checks the buyer's legal entity block in a UBL invoice or credit note (cac:AccountingCustomerParty, cac:Party, cac:PartyLegalEntity). It must not contain cbc:RegistrationExpirationDate, the date until which the buyer's company registration is valid. The buyer's name (BT-44) and company registration number (BT-47) sit in the same block and are not targeted by this check.

Why it matters

The rule excludes this date from the buyer's legal entity details. The warning depends on the element being present, not on whether the registration has expired.

How to fix it

Configure your UBL export to omit the buyer's registration expiry date. Changing the date or leaving the element empty does not clear this warning. If you edit or generate the XML, remove cbc:RegistrationExpirationDate from cac:AccountingCustomerParty/cac:Party/cac:PartyLegalEntity. Recheck the file in Klarbon.
