CII-SR-304: Do not add a requisition reference

What it means

The check looks in the agreement part of the invoice header for a reference to a requisition (ram:RequisitionerReferencedDocument), the internal request in the buyer's organisation that led to the order. 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 does not read the requisition reference, so it is not used to route or approve the invoice. It is worth fixing if the buyer asked you to quote it, because it will not reach them in this field.

How to fix it

Remove the requisition reference from the invoice in your invoicing software, or from the export settings that send it. In the XML, delete the ram:RequisitionerReferencedDocument block. Ask the buyer which reference they need: the buyer reference (BT-10) and the purchase order number (BT-13) are the fields the format provides for what the buyer wants quoted.
