Write an escalation which should run every minute and have condition as current time = Change Scheduled Time.
when it matches, execute the filter which will trigger BAO.
Thanks for the reply. I dont want to do a polling, Is there any other way with out polling every minute ?
I am not a Remedy ITSM expert. One needs to find a way to notify TSO (formerly BAO) when "scheduled start date" has reached. Either Remedy ITSM generates a notification as suggested by Aryan or one can write a scheduled job in TSO to query all records in a form , like CHG:Change_Interface form. The query should look for all CRQ records with status set to Work_in_Progress (or Implementation_In_Progress, don't remember) and "scheduled start date" is greater than current "epoch time" (make sure timezones match).
