NL-R-009
For suppliers in the Netherlands, if an order line reference (ram:BuyerOrderReferencedDocument/ram:LineID) is used, there must be an order reference on the document level (rsm:SupplyChainTradeTransaction/ram:ApplicableHeaderTradeAgreement/ram:BuyerOrderReferencedDocument/ram:IssuerAssignedID)
What does this rule mean?
An order line reference is used without an order reference at document level.
Without the purchase order number at document level the line reference cannot be resolved.
