IS IT ANYWAY POSSIBLE TO RESTRICT THE USER FROM CANCELLING OBLPN AND NOT BE ABLE TO TAKE THE ORDER BACK FROM the PACKED STATUS?

In simple words a need any option which allows me to restrict any user that if the order is in-packing or packed status the only way is to ship the order not any other way possible. means no one can take the order back from in-packing or packed status.

Removing the screen from the users group menu - I know this solution, and I don't want this solution. I just want any error msg appear when anyone tries to do so.
