Requirement

Read Only User Portal Purpose : Review and audit the cases in the system.

I have a requirement to implement a portal for the Read only user, where all the case related information should be displayed in read only mode.

1. Read Only User should be able to search a CaseID using OOTB global search and open the case in read only mode.
   1. Current Behavior: Opening the case in “Review harness” but inside the harness the assignment is clickable and directing to perform harness.
2. Read Only User should be able to open the Case from the worklist in read only mode.
   1. Current Behavior: Opening the case in “Perform harness”
3. Read Only User should be able to only open/download the attachments belonging to the opened case.
   1. Current Behavior: In the above two modes, can add and remove attachments.

As per the requirement, we should restrict the “perform harness” and what anything clickable in “review harness” when opening the case to review by the read only user.

How to achieve this with limited rule modifications?
