Prospective Accounting from Third Party source is not working as per Accounting requirement

Summary:

We are using RMCS to calculate revenue from a Third party system. As per the requirement from business , RMCS should generate prospective accounting by performing reallocation at the time of obligation closure or adding obligation to an existing contract. We are attaching an example of the scenario which we want RMCS to generate allocation and accounting . We have tried few scenario in RMCS but it is performing reallocation based on the original SSP and not the remaining SSP and remaining term at the time of obligation removal.
Any inputs regarding this scenario would be of great help.
