To associate a Rational ClearCase activity with the current ClearCase view, use the ClearCase Set Current Activity option. ClearCase associates any future check out of files within this view with the activity you select.
Note: You cannot create a new ClearCase activity for the view during this operation. To create a new ClearCase activity for the view, you must explicitly check a file that is within this view in or out.
This option becomes active after you connect to ClearCase.
