Setting Retroactive Alarms

Retroactive alarms are alarms for past events that did appear before the event because the user was not logged in. By default, the Siebel application is set to display up to 14 days of past retroactive alarms for missed events. You can change the number of days for retroactive-alarm display by editing the RetroAlarmInterval user property of the Alarm Manager business service.
