ROU calculation during Lease modification

Summary:

Our customer wants to understand what calculation logic is behind when calculating the amount by which ROU needs to be reduced/increased during Scope Decrease/Increase.Would you please be able to provide some documentation on the calculation logic as currently there is a variance between how Oracle is calculating vs their existing system Anaplan. I have attached one excel sheet and you can see Tab-JE Flows Row 49 Col Z , how is this figure arrived

Thanks in advance
