Coverage Discount is not applying on RMA Work Order

I have defined Coverage Level Discounts on certain Service Activity, Created Subscription in Subscription management, add the Warranty Item create in Product information management, The Coverage is attached to the Warranty Item,

In Subscription within Warranty Item, In Covered Level Subtab, I have attached the Asset on which we have to make The RMA work Order

The service activities are defined in Coverage level.

In coverage Entitlement Type i have Selected is (Internal Service Request Subscription Entitlements) because it seems relevant to our business process, Correct me if i am wrong.

Now, The problem is that, whenever i create the RMA work order with the same asset which i have attached in subscription covered level and also with the same activity which i have defined in Adjustment in Coverage The discount is not reflecting on RMA work order Charges.
