I am facing an issue in the testing of Multiple Element Allocation where I have configured the items standalone selling prices and MEA Templates. The items need to fetch the base sales price when the user goes for revenue allocation.

However the system is not fetching the details of the base sales price when we are going for the revenue allocation in the billing schedule. This problem is persisting even when it has been tested for 2-3 times atleast.
RG101: Laptop , base sales price 1200
RG111: Subscription Base sales price 300
Please respond as to what can be the issue regarding this failure of fetching the price from the item master of these products.
