Preventing Inheritance of Identification Rules Between cmdb_ci_computer and cmdb_ci_server

[颯史小]

Using ServiceNow’s out‑of‑the‑box features, is it possible to stop the identification rules for cmdb_ci_computer from being applied to the child table cmdb_ci_server?

Also, if a child table has no identification rule of its own, does it automatically inherit the parent table’s rule?

[Mark Manders]

Yes. If no rules are applied on a child class, the parent rule is inherited. So you need to add a rule for the server table to counter the computer one (or move the computer one up to only run on a different child class, depending on the exact requirement).

NowLearning has some excellent courses around this topic.
