Why Manage Ownership Screen is not hardcoded when all entities are locked for the period?

In the FCCS application, the "Manage Ownership" screen is currently allowing changes to be saved for locked periods. This behavior is causing consolidation jobs for the current period to fail and is prompting users to reopen all prior locked periods where ownership changes were saved by mistakenly. This behavior creates uncertainty in financial data and causing loss of data for Day or few hours where business users modified the data in FCCS application.
