When a period is locked, any time that has been submitted but not yet approved is also locked down. The approving manager must request that another manager (or administrator) unlock the sheet so that it can be approved. The following details how to create a time lockout exception to approve time. If the approving manager has the appropriate security rights, he or she may bypass the exception request process and manually create an exception for the sheet.
Select Approval Workspace from the menu (Menu > Views tab > Approval Workspace).
Select the Time & Expense Approval tab near the top of the screen.
Click the Exception Request button 
on the toolbar.
Select the sheet to open from the Exception request for list. More than one sheet can be selected.
Select to which Manager the exception request will be sent. This list is comprised of all users who have access to the Time Lockout view.
Enter a Reason for the request.
Click Submit.
The selected manager is sent an e-mail notifying him or her of the request. The selected manager must approve the request using the Approvals view.
