fatalEN 16931EN 16931 business ruleCIIUBLBG-25BT-153
Each Invoice line (BG-25) shall contain the Item name (BT-153).
An invoice line has no item name (BT-153).
Add BT-153 (UBL InvoiceLine/cac:Item/cbc:Name, CII SpecifiedTradeProduct/ram:Name). A short name is required; longer prose belongs in the item description BT-154.
CII — context $Invoice_Line
normalize-space(ram:SpecifiedTradeProduct/ram:Name) != ''
UBL — context $Invoice_Line
normalize-space(cac:Item/cbc:Name) != ''
Nothing is stored, and the whole invoice is checked, not just this rule. A PDF only works if it is Factur-X / ZUGFeRD — a PDF with the invoice XML inside it.
