The use case is that when a Change Request(an issuetype) is in "Closed" status ONLY users of a particular user group should be able to edit or modify links,attachments,issue fields of all Story/Features in that current sprint.
Just changing the workflow property wouldn`t work as when the Change Request for that Sprint is not in closed all users should be able to edit and modify issues.
Also we have Power Scripts, so using SIL can also be an option if there is a way of achieving this using SIL.
I have tried the below automation rule with "Set entity property" action but it is not disabling the edit permission.
