Exclude CI Classes for De-Duplication tasks

[Nishanth Nagesh]

Hi All,

I need to allow the De -Duplication tasks to be created only for specific CI Classes. Two options that I could think of was

1. Create identification inclusion rules - But the impact is global [ https://docs.servicenow.com/bundle/orlando-servicenow-platform/page/product/configuration-management/task/create-id-inclusion-rule.html ]

2. Business Rule on de-duplication task table - This can be done by fetching the values in Internal Payload. Not sure if it is reliable.

Please advise.

Also, identification inclusion rules are only used during IRE look ups and not when the cmdb health metrics are running.

Thanks Patrick.

Hi Patrick,

We have configured the Health Inclusion Rule (for Duplicate metric) as you have mentioned, however, we still see de-duplication tasks getting created even for the classes we don't want.  Could you please advise, if we need to do any additional step(s) other than Health Inclusion rules?
