How do I restrict user from doing any activity on invoices and payments after secondary ledger close

Summary:

How do i restrict user from doing any activity on invoice and payments after the secondary ledger is closed and primary ledger is open.

For example: Primary Ledger - 1 Jan- 31 Jan

Secondary Ledger - Closed 15 Dec-15 Jan, Open 16 Jan-15 Feb

Current date is 22 Jan, user is voiding the payment of 9 Jan, he is able to void it in 9 Jan because back date is enabled.

Here the issue is, even if user is able to do void such payments, but while running the subledger period close exception report, the accounting of these event get stuck.

similar in case of invoice cancellation, accounting gets stuck.
