A task is created any time a user is assigned an asset in Joy. By default, when a user completes a task, its status automatically changes to Closed. When a task has a Closed status, it moves into the Completed column on the Tasks page.
Manually closing a task
In some situations you may want to manually close a task. For example, imagine Joseph's role has changed and his new position no longer requires him to review a FlexDoc.
Your ability to manually close a task will depend on who the task is assigned to and your permissions.
To close a task, either view the task or find the task’s card on the Tasks page. Click the 
More Actions icon and Manually Close Task.
The Manually Close Task window will appear.
