Hi ​@ctoniazzo,

I assume user have full access for Quick Reports and Quick Report Detail screen.

Please remove access for these screen, and grant access for Order Report screen only. 

Order report screen allows user to View/Execute granted reports only.

Is there a way to prevent users from seeing Operational Reports from the Order Reports screen?

I also assume by locking down the Quick Report Details screen only, users would still be able to delete quick reports???

​@ctoniazzo, It is completely controllable, restrict Operational reports access for desired Users, and user would not be able to view/execute Operational reports from Order Report screen.

Yes, user won't be able edit or delete Quick Report(s) once access for Quick Reports and Quick Report Details screen access restricted 

How can we restrict Operational Reports to group of users?

​@ctoniazzo You need to configure End User Role/Functional Role accordingly, and revoke desired Operational Report projections.
