Create CMDB data Manager policy based on Principal Class

[Yves-Robert Rei]

Hi, we are trying to create a CMDB Data Manager Policy that would be based on CIs that are contained in a Principal Class. There are no filters avaialble to identify the notion of Principal Class in the Data Manager. As anyone encountered this issue and have a workarounf that is not to manually add each of the classes where Principal Class = TRUE in the policy?

I have the same problem in the CMDB query builder where I cannot build a CMDB query on a CI where the parent is in a principal class 

Thanks

Hi,

It's because the information about a CI Class being Principal class is stored in the CMDB Class Information [cmdb_class_info] table. That's not accessable from a CI using references but requires more advanced logic.

We are considering a custom "display-only" field, added to each CI, to denote whether that CI is a member of a Principal Class. This seems like such a basic & important piece of information.  Is there a logical reason why ServiceNow makes it so hard to get to?

Wouldn't it be nice if you could use the filter editor to add: Class is (dynamic) Principal Class?
Sorry to disappoint.

But if you think it's a good idea, vote for it!

Dynamic Filter Option for CMDB Class is (dynamic) Principal Class
