You can view all or some workflow tasks. You can filter tasks you do not want to view. For example, if you want to view only Session tasks, you can hide all other tasks. You can view all tasks at any time.
To filter tasks:
Click Filters > Tasks.
Click Filters > Deleted Tasks.
The Filter Tasks dialog box appears.
Clear the tasks you want to hide, and select the tasks you want to view.
When you filter a task, the Gantt Chart view displays a red link between tasks to indicate a filtered task. You can double-click the link to view the tasks you hid.
