IRE Data source rule is not working for any CMDB class

[SaloniPatekar]

As per ServiceNow docs, we can prevent a specific discovery (data) source from inserting new CIs for a specific class by creating IRE Data source rule for a particular class. 

We have created IRE Data source rule for Computer class with Data Source as ServiceNow and selected 'Insert not allowed' checkbox, in order to restrict CI creation from 'ServiceNow' Discovery Source, but CIs are still getting created on the computer class with Discovery Source as 'ServiceNow'. 

Need to understand a clear functionality of IRE Data source rule and what parameters to be used in order to configure this rule?

Hi @SaloniPatekar 

 Ensure the rule is correctly scoped and tested to verify its effectiveness.

Hi @Satishkumar B 

The rule is correctly scoped and is Global, upon testing we have identified that it is not working as expected.

Any suggestions how that would work?

Hi @SaloniPatekar ,

Make sure that only a single IRE data source rule is active for Computer CI class and ServiceNow data source.

Check the Discovery source of the CI inserted whether it is populating discovery source as 'ServiceNow' correctly or not.
