How to fix it

1. Open the XML file and find the element cbc:IssueDate.
2. Add or correct the element the way the wording of the rule above asks for.
3. Save the file and check it again with our checker. It runs in your browser, the file is never uploaded.

A correct UBL 2.1 snippet

<cbc:IssueDate
    xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">2026-09-11</cbc:IssueDate>

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.
