Immediately Ending a Business Process Instance with the Exit Activity in BPEL 2.0

You can use the exit activity to immediately end all currently running activities on all parallel branches without involving any termination handling, fault handling, or compensation handling mechanisms. This activity is useful for environments in which there may not be a reasonable way for dealing with unexpected, severe failures.

Note:

Any open conversations are also impacted by the exit activity. For example, other partners interacting with the process may wait for a response that never arrives.
