Use
By assigning a priority to a notification, you can specify the importance and urgency of the notification.
Prerequisites
You have defined priorities in Customizing for the Plant Maintenance and Customer Service application components. You can define an interval for performing the notification for each priority.

For example, priority 1 can mean: Execution is to start 2 hours after creating the notification and is to be finished within 2 days.
Procedure
The system calculates the required start and end of the maintenance notification in the background based on the definition of the priority, and enters these dates in the relevant fields.
If you want to see the newly-calculated dates, call up the scheduling overview by choosing Goto
® Schedule overview.When you release the notification, the system also calculates the dates for the tasks. This is done on the basis of the factory calendar. The dates for the tasks are displayed on the tabstrip Tasks.
