What it means
The check requires schemeURI to be absent from the specification identifier (BT-24), invoice number (BT-1), invoice line identifier (BT-126) and seller's item identifier (BT-155). It does not check other attributes or other identifiers.
Why it matters
The CII mapping for these fields does not include a URI identifying the identifier scheme.
How to fix it
Find the affected ram:ID under ram:GuidelineSpecifiedDocumentContextParameter or rsm:ExchangedDocument, ram:LineID under ram:AssociatedDocumentLineDocument, or ram:SellerAssignedID under ram:SpecifiedTradeProduct. Remove only schemeURI from that element and keep its value. Save or regenerate your CII file, then check it again.
