CII-SR-302: Do not add a price list reference

What it means

The check looks in the agreement part of the invoice header for a reference to a price list (ram:PriceListReferencedDocument), the list the prices on the invoice come from. EN 16931 has no field for it.

Why it matters

This is a warning, so the invoice is still accepted. A recipient that follows the standard reads the unit prices on the lines and ignores the price list reference. It is worth fixing if the buyer checks your prices against a named list, because they will not see which one here.

How to fix it

Remove the price list reference from the invoice in your invoicing software, or from the export settings that send it. In the XML, delete the ram:PriceListReferencedDocument block. If the buyer needs to know which price list applies, name it in the invoice note.
