If your administrator has enabled the service field on the request creation page, and has created the necessary request type for service, you can associate your requests each with a single service when you create and submit the requests. For details about enabling service for requests, see Enable service for requests.
To specify a service for a request:
On the Create New Request page of PPM, from the Request Type list, select the request type that has service enabled.
For example, Email Account.
The Create New <Request Type> page opens. Note that the Service field is available.
In the Service section, click the selector icon for the Service field.
The popup window lists all services available.
Select a service from the list that you want to associate with the new request.
Complete other fields on the page as necessary.
