Partial shipment is not allowed in back to back sales order in oracle fusion

Summary:

We need to ship a partial quantity from a back-to-back work order, but currently, this isn't possible. Although the supply status shows partial goods available, it gets backordered during the pick wave release. Shipping is successful only when the entire work order is complete. The "partial shipment allow" flag is set to "Yes" in the sales order. According to Oracle documents, the features "Update Attributes on Split Order Lines for Partial Shipments" and "Improve Supply Tracking for Sales Orders in Your Back-to-Back Flows" must be enabled. However, "Improve Supply Tracking for Sales Orders in Your Back-to-Back Flows" is not visible
