What is BR-DE-CVD-06-a?
BR-DE-CVD-06-a is a fatal validation rule defined in the XRechnung (Germany) specification (DEU national rules). It validates the ItemClassificationCode element under Item > CommodityClassification in the UBL invoice XML.
When this rule fires, the invoice is rejected by Peppol access points and never reaches the buyer.
