Using Lists to Customize Forms
You can use lists in Service Manager to classify different objects, such as incidents, change requests, activities, or configuration items. A list represents a property of an object, and it includes one or more list items. Each list item represents a possible value for a property.
Lists are used in forms and dialog boxes throughout the Service Manager console. Lists and list items make it possible for users to select a value from a predefined list of values. When you use lists, you can customize the console to reflect the business practices of your organization. Additionally, Service Manager contains several predefined lists, such as the Incident Classification list.
For example, when you are creating an incident, you notice that Printer Problems is an option under Classification Category. At your company, some standard laser printers in your accounting department might be used as specialized check-writing printers. To better route incidents, you want printer-related incidents to be categorized as being either for standard laser printers or for check-writing printers. Because lists are customizable, you can add a list item, such as Laser Printers and Check-Writing Printers, to the Classification Category list when you create an incident. Optionally, you can build lists as a hierarchy; for example, laser printers and check-writing printers could be listed under printers. To do this, you can add Laser Printer and Check-Writing Printer list items to the Incident Classificationlist.
About List Items
In Service Manager, several default list items exist. It is important that you not delete the default list items. Each default list item is defined by a globally unique identifier (GUID). Some of the default management packs reference these list items by their GUID. If you delete a list item, some management packs or workflows might not work.
If the name of a default list item causes an issue in your environment, you can change the display name of the existing item but leave the GUID intact. For example, you can change the name of the Printing Problems default list item to Laser Printing Problems if that is better in your environment.
Support Group List Example
Open the System Center Service Manager 2012 R2 Administrator Console and navigate to:
Library > Lists and select Incident Tier Queue, right click and select Properties.
Click Add Item and then fill in the Name and Description fields.
When we create a new Incident, the two new support group items now appear in the list.
