BR-DE-CVD-06-b:Missing CVD Classification for Clean Vehicle Attribute
Fix: Invoice Navigator automatically fixes this issue by updating the BT-160 field in your Invoice. Upload your invoice to fix this automatically.
When an invoice line has an AdditionalItemProperty with Name="cva" (clean vehicle attribute), it must also have exactly one CommodityClassification with ItemClassificationCode[@listID="CVD"] containing the vehicle category. This is required for German XRechnung invoices under the Clean Vehicle Directive.

What is BR-DE-CVD-06-b?
BR-DE-CVD-06-b is a fatal validation rule defined in the XRechnung (Germany) specification (DEU national rules). It validates the ext:UBLExtension element in the UBL invoice XML.
When this rule fires, the invoice is rejected by Peppol access points and never reaches the buyer.
Target path: //ext:UBLExtensions/ext:UBLExtension[not(contains(ext:ExtensionURI,'xrechnung'))]
Why This Error Matters
The Clean Vehicle Directive (CVD) requires consistent data when reporting clean vehicle purchases. The CVD classification must be present whenever the cva attribute is used. Missing this causes validation failures for German XRechnung CVD invoices.
BR-DE-CVD-06-b is a hard failure — the invoice must be corrected and re-sent before it can reach the recipient.
Invoice Navigator can automatically correct this error in your pipeline. The fix is applied with full audit evidence, so your compliance trail remains intact.
