Terminating Event with Decision Step.

[Vinod Ramchandani]

hi everybody . . .
 
i want to terminate the decision step with event-trigger.
i have a decision step which ask the approver to approve the requisition.
i need to rollback the "decision workitem" when "releasestepcreated" or
"significantalychanged" events are triggerd from the requisition object.
decision step is defined on different business object that is DECISION.
i want to terminate this step with event-trigger on business object BUS2105.
i have defined the above mentioned events as a terminating events of the
decision step,
but it doesnot work as expected.this is working with any other activities
like "release"  and "reject" - those are defined on BUS2105.
 
can anybody suggest how can i achieve this functionality?
i appericiate any kind of inputs on the same.
 
thanks and regards,
