Do the default movements recalculate when the opening balances change

Summary:

I have a situation where a customer wants to reload the statutory balances into the last period of the prior year, after multiple months have been load for the current year and I am wondering what happens to the default movement for the months of the current year when the opening balances change. Do they recalculate to bring the closing balance back to what was loaded to FCCS_ClosingBalance_Input or do the default movements not recalculate, creating a variance between the closing balance loaded and the closing balance calculated by the system?

Detail:

Data is loaded YTD to FCCS_Managed Data→FCCS_Closing Balance_Input.
