Description -

In case of any stuck threads within the application because of corrupted Contract then we need functionality to suspend/rollback to previous state(refer to Use case for more details)

Use Case
To reassign a notification activity that is not yet complete, select the reassign icon
To suspend a process activity that is not yet complete, select the suspend icon in the Suspend/Resume column. All further processing for the process is suspended until the process is resumed.
To resume a suspended process activity, select the resume icon in the Suspend/Resume column. Processing for the process is resumed and any activities that were transitioned to while the process was suspended are now executed.
To skip an activity and force the workflow to transition to the next activity, select the activity and select the Skip button. In the Skip page, enter the result value to assign to the activity if required.
To retry an activity, select the activity and select the Retry button.
To rewind the workflow to an earlier activity stage, select the Rewind button. In the Rewind page, select the activity you want from the list of activities that the Workflow Engine has reached. Workflow stops processing at the current activity and resumes processing at the specified activity.
To cancel the workflow, select the Cancel Workflow button. In the Cancel page, select Apply. The Workflow Engine sets the status of the workflow to #FORCE, and all processing for the workflow is canceled and cannot be restarted.
