Common Data Model help

The following table lists the out-of-the-box classes under the BMC_BaseElement class. Classes with a background color are abstract classes, which exist only to organize subclasses and enable you to add a layer of organization. An abstract class has attributes but you cannot create instances of this class.

Most of the classes listed in the table are of the CI class type. The following number notations indicate the other class types in the table:
1 Asset class type
2 Asset class type (Rules-Based Asset class)
3 CI and Asset class type

Fieldsets for classes

Each class has a corresponding fieldset in the Base Element object. A fieldset contains a group of fields for that class. For example, the Printer class has a corresponding Computer System fieldset in the Base Element Object and contains the following fields.

Class Name	Fieldset	Fields
Printer	Printer	Average Pages Per Minute Horizontal Resolution Marking Technology Number Of Trays Paper Sizes Supported Port Name Printer Capabilities Printer Language List Printer Type Vertical Resolution

To include additional fields in a fieldset

Edit the required fieldset in the Base Element object.
From the list of available fields, drag the required field in the In the Field Set list.

Note

If you want to add a field in a fieldset that is not included in the list of available fields, you have to create a custom field. This custom field is included in the list of avaibale fields, which you can then add in the fieldset.
