Hello @chriskk Welcome back to developers community!!!
To get an email with the comments you can configure revokation email under SystemConfiguration with below entry
<entry key="remediationNotificationEmailTemplate" value="EmailTemplate-Certification-Revoke-Notification"/>
This will trigger an email when revoke happens and comments are available as an inputs arguments by default. You can add below code in the email template to see the comments
#if($comments)<b>Comments:</b> $!comments #end
You can write your own logic email template check if the certification was completed by a user or automatically by the system:
#if($certificationItem.getAction() == “Revoked due to certifier did not complete the review. Revocation occurred automatically in compliance”) <b> Entitlement/Access has been automatically revoked due to user did not take any action</b> #end
And Also you can configure default comments under certification template. Below is target certification configuration and I assume this config would be same for other cert templates
I am not sure about a note/ comment can be seen under identity warehouse, but comments are storing under spt_identity_history_item. You can access comments via code
