Enable User-System Process Mode
In User-System Process mode in the Process Editor, a. task is always tied to, and accompanied by, a responding system task. Whenever you add a task to a Process, an accompanying system task is also created.
A system task represents a system response to a user action. This response also acts as the system precondition for a following user action. Put from the perspective of user stories, a task is always preceded by one system task, and followed by another.
When Business Process mode is enabled, system tasks are hidden, but still exist.
To enable User-System Process mode, click the User-System Process mode button in the artifact toolbar to display system tasks.
