After creating an activity, you may need to change its properties at a later time. If you have activities that you no longer need, you can delete them. Deleting activities deletes them from the server. It also deletes any assignments of the activity to users and user groups, as well as any record of users taking that particular activity. In addition, deleting an activity deletes all its sub-activities. You cannot delete the root activity in a knowledge path.
Users see changes to a knowledge path the next time they return to the Subject Selection page.
To edit an activity:
in the Edit column for the knowledge path.
in the Edit column for the activity you want to edit.
To delete an activity:
in the Edit column for the knowledge path.
in the Delete column for the activity you want to delete.
