KF-XML-RACINE: The XML is not a CII invoice
This code shows up when an electronic invoice is validated. Here is what it means, why it fires, and what to change in the file.
Why this code appears
The document root is not CrossIndustryInvoice. This may be a UBL invoice, an Order-X purchase order, or another XML format filed under an invoice name.
How to fix it
Check what your software produced. Factur-X uses the UN/CEFACT CII syntax; UBL is another syntax accepted by the standard, but it is not embedded in a PDF under that name.
Where it happens
This check is ours, not a code from the standard: we do not cover enough of EN 16931 to borrow its numbers, and a misattributed official code would send you to fix the wrong field. It concerns XML.
