Reading the menu role user logged onto

Folks,

Is there a way to find out in a program invoking say a static class or reading table, which user menu role MDGS_MENU_04 or MDGC_MENU_04 a user in current session logged onto. I want to make certain enhancement active based on menu role they logged onto. Can't use security role as user can have multiple diverse roles assigned.

Thanks in advance.

Sincerely,

Kartik.
