2 Ways:
Difficult: Goto G901 in JDE and copy menus or set up masking.
Easy: Dont try and secure menus at all but use an ALLOut program to do it for you.
It depends what you need to do. If this is a one-off thing then use JDE, if this is an ongoing requirement and you need to secure your system, you should view one of our webinars because securing your system using JDE only is time consuming and doesnt work too well.
