Hope this might be helpful:
The "Ref. Order No." and "Sell-to Customer No." fields in the Requisition Worksheet are often blank because lines with "Purchase" as the Replenishment System are for general inventory replenishment (e.g., minimum stock, forecast), not direct sales order fulfillment. These fields only populate for "Order" (Special Order or Drop Shipment) replenishment. To see underlying sales order demand, use the Inventory - Availability Plan report.
