This video explains what service order templates are, what they are used for and provides a short demo. 

Service Order Templates define reusable sets of service-related data that minimize the amount of time required to create a service transaction. In the service industry more often than you know you are creating service orders very similar to the ones created before. Example standard maintenance procedure of equipment, where you will need filter replacement, oil change, piston check to be done each time. To be more efficient in creating service orders for a standard maintenance procedure, templates are created. These templates are used to create service orders.
