You can assign vehicle parts to services when you create or edit service requests in order to specify which vehicle parts should be serviced.
On the Operations tab, click Service Request List, and then on the Service Requests page, add a new service request or edit an existing service request.
In the Service Request detail view, click Edit in the Services section.
In the dialog box, click the box, select the check box next to the appropriate services, and then click Add.
In the Vehicle Part dialog box, click the appropriate vehicle part in the Available box, click the right-pointing arrow to move this vehicle part to the Assigned box, and then click OK.
Note If you assign multiple vehicle part to a service, multiple instances of the same service will be added to service request (one instance for each vehicle part).
