The control task
The control task is used to control the execution of the workflow. You can stop, abort, or fail the parent workflow or top-level workflow by defining the appropriate condition in the control task.
The control task acts as a green signal or red signal. If you use a control task in a branch in the workflow and if everything is moving smoothly, that is, there are no issues with the process, the control task will not even get triggered. It will act invisible. However, if the process catches up with the issue, the control task will take control, and based on the option you select in the properties, it will stop, abort, or fail the workflow or the top-level workflow.
