Changing the period
Uwaga:  If you change the current period while you, or any other users,
                           		  have any sessions open in 
                           		  SunSystems,
                           		  those sessions continue to use the previous current period. As each new session
                           		  starts, the new accounting period is used. In new ledger entry sessions, a
                           		  message is displayed notifying the user that the period has changed since they
                           		  last used ledger entry.
