Using the Operations Console, you can terminate one or more running work items. If an activity in the work item initiated an external task on a remote computer in your environment, the external task continues to run. For example, if the Execute SQL Commands & Scripts activity executes a stored procedure, and you terminate the work item, the stored procedure continues to run until it completes its task.
To terminate a running work item in the Operations Console:
If you want to see work items associated with a specific process, under Processes, click the appropriate process.
Under Work Items, select the work items you want to terminate.
Click Terminate, and then click Yes.
