Automatic Determination of Tasks 
Use
The system can automatically determine which tasks should be performed first, based on the predefined parameters response profile and service profile. The response profile and service profile determine the times and the time interval within which your company should respond to a notification in a particular way:

You create a notification at 10:00 am. The response profile defines a time interval of two hours for the task code "Call back customer" and a time interval of 4 hours for the code "Check whether technician is on site". The times defined in the service window are 8:00 am to 12.00 noon and from 2:00 pm to 6:00 pm.
In this case, you should call back the customer by 12:00 noon to discuss or clarify the problem. If you have to send a technician to the customer site, the technician must arrive by 4:00 pm.
Prerequisites
Your system administrator must assign both a response profile and a service window to each notification type in Customizing for Notification Processing.
