The calendar period can be rolled back if needed to be reopened. To roll back the calendar period for a balance, follow the steps below.
Click CoreTime, then click System Params.
Click Balances, then click Calendars.
Select the drop-down and select the relevant balance.
Untick the incorrectly closed period to re-open it, then click Save.
📌 Note: Only move a balance calendar period backwards; never use this option to advance the calendar.
Be careful not to move the calendar back too far. To ensure this is working fine, perform a Balance Recalculation after changing the calendar. If there are any errors, change the balance calendar back.
