Prevent data source to update any attribute in a particular class.

[Canjura]

Hi,

We have a Intune integration (among others), but the Server data in Intune needs to be cleaned before we can use it to update CIs in our CMDB.
The rest of the information from Intune (end-user devices) is OK and we're updating the Computer System class with that information.
We have Reconciliation Rules at the Computer System table for the different data sources, and the Server table inherits those recon rules.
The Intune's Server data quality is not good to the point that there's no clear attribute in the Intune side that we can use to filter-out servers via a transformation map.
How can I prevent Intune from updating ANY attribute on the server table?

Thank you.

Give this a try.  You can use this in an onBefore script to skip the records.

Can you try like this.  Select a field that is not at all related to Intune when you create Recon Rule.  Here I selected "Comments" field only from Server table and Discovery Source as "Intune".  Provide a priority to it and save.  This will make sure Intune can only make changes to comments field which will never happen.

Thanks,
