    • Extend and update CMDB CI Class Models store app classes and rules when using third-party integration tools.

    When using a third-party tool to integrate with ServiceNow apps, gaps can occur between the integration and different CIs. Some of the integrated tables and classes may be missing classes and rules not included with the CMDB CI Class Models store app.

    The classes and rules in the following table enable you to add and extend the CMDB CI Class Models store app for integrations:
