Creating Repeating Notifications

You can configure a notification so that it generates repeatedly until a Termination rule becomes true. For example, you can send a service technician an "I Am Assigned a Problem Ticket" every two days until the item is closed.

For details, refer to:

To create a repeating notification:

Create or edit the notification that you want to send repeatedly. (For guidance, refer to Creating Standard Notifications.)
Select the Escalations tab.
In the Termination Rule area, select or create a rule that stops the repeated notifications from generating. In the example above, the Termination rule might be "Item Is Closed." For details, refer to About Rules and Conditions.
In the Repeat Action Parameters section, select the Repeat check box.
In the Every area, specify the time interval for repeating the notification until the selected Termination rule becomes true.
Optionally, select a calendar from the list to calculate the repeat time interval. For example, you may not want to generate repeat notifications on weekends. If you select a calendar that reflects operational hours of Monday through Friday from 9 a.m. to 5 p.m, an 8-hour period that begins at 2 p.m. Friday repeats on Monday at 1 p.m. By default, a 24-hour calendar is selected. For details, refer to Calendars.
Save your changes.
Select the Subscriptions tab, and then verify that the correct users are subscribed to the repeated notification.
Tip: Be sure to verify subscribers have permissions to view items on which the notification is based.
