The task owner can view tasks belonging to business processes they own and perform operations on behalf of any of the task assignees. Additionally, the owner can also reassign, withdraw, or escalate tasks.

If you do not specify a task initiator on the General tab of the Human Task dialog, it defaults to the owner specified here. In the Owner field of the Advanced tab, enter the task owner name or click the icon to the right to use the Expression Builder to dynamically specify the owner of this task.
