Warning

UBL-CR-241: Leave the company registration date out of the buyer's details

In short

Warning: worth checking.

UBL-CR-241 means the buyer's legal entity details contain a registration date (RegistrationDate), which EN 16931 does not use. Remove the date and keep the company registration number (BT-47) if you have one.

On this page

What it means

This rule checks that the buyer's legal entity block, cac:PartyLegalEntity, does not contain a registration date, cbc:RegistrationDate. That is the date the company was entered in a register. The buyer's name (BT-44) and company registration number (BT-47) belong in the same block, but this check concerns only the registration date. It applies to UBL invoices and credit notes.

Why it matters

This rule excludes the registration date from the buyer's legal entity details. It checks whether the element is present, not whether the date is valid.

How to fix it

Configure your UBL export to omit the buyer's registration date, rather than just clearing its value. Keep the company registration number (BT-47) if you have one. If you edit or generate the XML, remove cbc:RegistrationDate from cac:AccountingCustomerParty/cac:Party/cac:PartyLegalEntity. Recheck the file in Klarbon.
