How to fix it
- Open the XML file and find the element
cac:OrderReference/cbc:ID. - Add or correct the element the way the wording of the rule above asks for.
- Save the file and check it again with our checker. It runs in your browser, the file is never uploaded.

xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">
<cbc:ID>2026-0142</cbc:ID>
</cac:OrderReference>The snippet is only the part of the document the rule is about. Put it in the right place inside your invoice; the namespaces are written here only so that the snippet reads on its own.
