An Invoice shall have a Specification identifier (BT-24).

Why it fires

The specification identifier tells the receiver which rule set to validate against. Without it a platform cannot route the invoice to a validator at all, so this is usually the first thing that gets rejected, before anything else is even read.

How to fix

Set the guideline specification identifier. In CII it is ExchangedDocumentContext/GuidelineSpecifiedDocumentContextParameter/ID; in UBL it is cbc:CustomizationID. For a plain EN 16931 invoice the value is urn:cen.eu:en16931:2017.
