You can do a PREP_PROCESS_REPORT for the list of schedules that you want to be monitored.
Then retrieve the current status of the schedule by
: SET &STATUS# = GET_UC_OBJECT_STATUS(,&RunID#,'STATUS')
The status for condition "STOP - Automatic Processing has been stopped" is 1563.
So if the status is 1563, you can send an email to support.
