If an organization requests that you take specific action on a dispatch, you can record that request through the Details panel. Requesting organizations can be an agency, such as the police or fire department, or any other organization involved in the activity.
When a service request has been recorded on a dispatch, the 
icon will appear in the Service Requests column of the Dispatches panel. Service requests are recorded in the activity object when the dispatch is closed and sent to Command Center.
The Service Requests section of the Details panel.
