Re: How to take a field from Service into Service Call object ?!
Josh is right. But if you don't want to use a Service Call custom field you can try another approach.
Open Administrator Console and go to Presentation/Search. Open Service Call and go to the "Show" Tab. From the list there check Service. Press OK and select Service. Press the button to the right of the Quick View panel and from the fields window select your field.
Now, on service calls, below the "service" field you 've go a mini panel that will list the values of the fields selected as quick view from the services.
