Stopping a Business Process Instance with the Terminate Activity in BPEL 1.1
The terminate activity immediately terminates the behavior of a business process instance within which the terminate activity is performed. All currently running activities must be terminated as soon as possible without any fault handling or compensation behavior. The terminate activity does not send any notifications of the status of a BPEL process service component. If you are going to use the terminate activity, first program notifications to the interested parties.
