You can also view and action the timesheets via the Assignment Information page directly.

Open the Assignment and go to the Progress tab. All the timesheets (non-blank) associated with the assignment will be presented on this page.

You can view the timesheets by clicking on the eye icon.

If the timesheet is editable (not approved/already generated), you will also have the option to edit/approve/delete/send approval to worker/send approval to client just like you do on the All Timesheets page.
