Hi @manan7108 Currently the filter is not supported in attribute sync. You may consider to use either Update provisioning plan where you can check the account type is not admin by using transform to update the attributes or use Before Provisioning rule to do the same for attribute updates.
You can try to use Before Modify Rule and write a logic which can identify the admin account like if admin account starts with ADM- or if there is any attribute that defines that the account is admin account, based on that you can stop the provisioning value to not modify the particular account even though SailPoint triggered attribute sync for both the accounts. This way you will be using before modify rule powershell script to not populate particular attribute for ADM account.
You need to use BP Rule, check the plan and remove Account Request for admin account if exists. But the synchronization never stops, its a never ending loop.
