Users who have been given administrative access can roll back the period.
To do so, the user will need to use either Client Details - Edit (Periods tab), or Client Periods - Edit in Troika Wealth Management. Using the Edit button to the right of the period, edit the period detail, removing the Final status and RO (Read Only) tick.
