What it means
The check requires UltimateCustomerOrderReferencedDocument to be absent directly under a line's SpecifiedLineTradeAgreement. The supported purchase order line reference (BT-132) refers to the buyer's order line, not automatically to the end customer's order.
Why it matters
The end customer's order reference is not interchangeable with the buyer's purchase order reference. This separate line element is outside the EN 16931 CII mapping.
How to fix it
Remove UltimateCustomerOrderReferencedDocument from the affected SpecifiedLineTradeAgreement. If the reference actually identifies the buyer's order, put its purchase order number in BT-13 and its line reference in BT-132. Otherwise, ask the buyer how to include any end-customer information they still need without mislabelling it. Recheck your file.
