This example illustrates how to trigger values from additional fields or a combo box (cascading validation list) by creating a service that uses a value based on the **OwnerTeam** field.

Before configuring this option, ensure that you have a standard user team called **Desktop Support** that it is populated with active employee names.

*Standard User Team - Desktop Support*
