Data Manager policy type "Delete related CMDB Entry"?

Damhoej · ‎01-13-2026

I am trying to figure out how to use the Data policy Delete related CMDB Entry.

The documentation is not helping and the latest slides from ServiceNow does not help either.

Does anyone have a step by step explanation (especially what options are for policy tables)?

The "Delete Related CMDB Entry" policy type covers deleting records from related tables (e.g. cmdb_key_value).

When Data Manager removes CIs from the CMDB, it can leave behind records in related tables. This policy type allows you to clean up the "orphaned" records in the related tables. You can use a filter condition that checks if the Configuration Item reference field for a record in a specific related list table is empty. Any matching records will then be automatically removed.

Basically is the idea of this type and use cases for it.
It is not for deleting disks related to a server 😉
When you select that type you have to choose from policy tables.
It is impossible to find documentation for this type (only one slide in the new slide deck from SN)
