Warning

CII-DT-048: Leave the code list link off a line's VAT category code

In short

Warning: worth checking.

CII-DT-048 warns that a VAT category code on one of your invoice lines has a listURI attribute. Remove that attribute without changing the category code.

What it means

For each invoice line, the rule checks ram:SpecifiedLineTradeSettlement/ram:ApplicableTradeTax/ram:CategoryCode (BT-151). It warns whenever that CategoryCode has a listURI attribute, even if the attribute is empty.

Why it matters

The listURI attribute gives an address for the code list. This rule excludes that address from the line's VAT category code, regardless of whether the address is valid.

How to fix it

Find the affected line's CategoryCode inside ApplicableTradeTax under SpecifiedLineTradeSettlement. Delete only its listURI attribute, not the CategoryCode element or its value. If your software adds the attribute, ask its supplier to correct the CII export. Generate the file again and recheck it.
