Oracle Forms

Hi,

I am repeating this again, I have not received any solution on this.

I want to enable/diable menus/submenus (in a .mmb) userwise upon user login.

There are many submenus, some staff needs access to some menus some does not. based on user login these shd be automatically set. Is there any solution?

many said like use roles, but how? creating a new user then assign a role to him, in this case how this new user can access the tables in application user when he logs in with his user account.

Thanks in advance...
