I want to prevent certain users from some menu items within my customized menu. How do i acheive that.
Initially i wrote a program unit attached to the menu module to single out the administrator from the other users but i get some compiling error message
e.g.

select count(*) into x from dba_users
where username='ADMIN';
IF X<0 THEN
MESSAGE('Access Denied See Administrator');
END IF;

I got error message that 'dba_users must be declared'

Pls help

If you're using an Oracle Forms Menu Module (MMB/MMX) you could use the built-in functionality. Create some menu related database roles, assign the roles to users and to the menu items you want in Oracle Forms.

In short:
1. On the database
CREATE ROLE MENU_ADMIN;
CREATE ROLE MENU_OTHERS;

2. On the database
GRANT MENU_ADMIN TO ADMIN
GRANT MENU_OTHERS TO ...

3. In Forms: Enable the role/menu security.

DBA_USERS is indeed not visible to just every user.

You could also check for USER. If USER = 'ADMIN', but that's not good practice, since you're hardcoding string literals. What will you do if there's an ADMIN2 or an ADMIN_BACKUP user?

Well, you need to have some active items left in your menu that are accessible to your users (Like the EXIT option):

----------------------------------------------------------------------
FRM-10247: No active items in root menu of application.

Cause: You tried to open an application but its root menu has no items that you can access. The root menu is either the application's main menu or another menu specified when Form Builder called Forms Designer.

Action: Notify your DBA.
