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.

Hi, check out https://docs.servicenow.com/bundle/newyork-servicenow-platform/page/product/configuration-management.... 

Create the health inclusion rules at the cmdb_ci class level. Examples on what I have done.

Thanks Patrick. Creating Health Inclusion rules for the duplicate metric will only affect the data displayed on the Health Dashboard using the metrics right? Will it stop the De-duplication tasks from being created?

It will stop the records and thats the data the dashboard uses. I would recommend deleting the dup tasks before you make the change so you have a clean baseline moving forward.

Hello Patrick the health rules only apply for Dashboard and metrics it won't stop the creation of the de-dup tasks from being created. I am having this issue just now and i am trying to stope this tasks from being created for Image class as the "dups" there aren't actual dups, i try creating the BR but they didn't stop getting created. I have this also confirmed from ServiceNow...

do you have run into any ideas of this? how to stop them with a BR?
