Configuration Item List is To Long

[JamesLindsay]

When in a list view of Incidents and needing to update the config_item field of the incident, often because it is empty, hitting the search button returns ever CI in the CMDB. How do I limit this to principal CIs?

Hi @JamesLindsay ,

Check below property and add your table on which you have cmdb_ci field. Filter will auto apply.

The list I am looking at is the incident table and it is in that list. It's not possible that I have 1.3 million CIs and all of them are in a Principal Class

In ServiceNow if a class is a principal class do extended classes also become principal classes? It does not appear so. Like cmdb_ci_netgear is a principal class but extended classes like IP Switch do not show to be principal in my instance. A quick glide record query shows that I only have 13K CIs within all 38 of my principal classes. So why does this list open a search window displaying 1.3 million?
