Star Item Cancellation on Quantity Reduction Post-Booking via oe_order_pub.process_order

In our stage environment, when we attempt to reduce the quantity of a line item after the order is booked using the oe_order_pub.process_order API, the associated star item gets cancelled. However, in our development environment, the quantity is successfully reduced, and the star item status remains unchanged. This indicates that the issue may be related to a setup difference—possibly a profile option or configuration. Could you help identify which setup parameters might be causing this discrepancy?
