Create a CI class (table) that is an extension of an existing CI class. Then create identification and reconciliation rules for the new class.
Before you begin
The class that is being extended must have its Is_Extendable field checked, indicating that the class is extendable.
Role required:- Itil_admin and personalize_dictionary: Required for editing the dictionary table

About this task
The CI Class Manager is a centralized location for managing CMDB tables and for creating a class that is derived from another CMDB class. Creating a class requires basic details such as a label and a name. Identification and reconciliation rules are also required to ensure that the class can be successfully identified by the identification engine.
For more information about extending a class and how attributes are derived from a parent class in that process, see Table extension and classes.
Procedure
Related Content
- Dependent CIs management
A life cycle update for a CI affects its dependent CIs. For example, when the CI that a dependent CI depends on is deleted, the dependent CI becomes orphan with no further use. To maintain the integrity and health of the CMDB, the system applies cascade-cleanup processes to dependent CIs that are affected by a life cycle update.
- CMDB record types
The CMDB contains the following major record types.
- Related Lists of CI components
Related lists in CI records display additional components contained by that CI, such as disk drives on a server and the rules that control the behavior of a network router.
- Reclassify a CI
You can upgrade, downgrade, or switch the class of a CI by modifying its Class attribute.
- Delete CIs
You can use the CI Class Manager to delete CIs that are no longer needed.
- View and edit class definitions and metadata
Use the CI Class Manager as a central location to explore the CMDB class hierarchy, CI table definitions, and class CIs. View the details of each table such as its label and fields, relationships, and all related metadata definitions.
- Update the list of classes in the Principal Class filter
Manage the list of classes that are included in the Principal Class filter to restrict the CIs that appear in CIs list views to only specific classes that you need. You can add or remove CMDB classes from the Principal Class filter.
- CMDB Identification and Reconciliation (IRE)
The Identification and Reconciliation module provides a centralized framework for identifying and reconciling data from different data sources. It helps maintain the integrity of the CMDB and some non-CMDB tables when multiple data sources are used to create and update CI records.
