How to restrict functions and menus available to a user in menus

Hello Friends, Using this article, i wanted to give brief on how we can exclude some forms/ function as security in oracle applications. plz see i am trying to use two different way to get the same functionality.
There are two possibilities:
A – Restrict an existing menu:
1) Log in as System Administrator responsibility
2) Find the name of the appropriate menu      Navigator: Application -> Menu
3) Create a new responsibility       Navigator: Security -> Responsibility -> Define
4) Assign the appropriate menu to the new responsibility
5) Enter functions in the Function and Menu Exclusions section of the form Responsibilities
6) Save
7) Assign the new responsibility to the appropriate user

Example:  Restrict a user to be able to do only Assignments in the Asset Workbench.
1) Log in as the System Administrator responsibility
2) Find the name of the appropriate menu:
Description: %Asset%
2) Create a new responsibility: ASSET – assignments
3) Assign the menu FA_TRANSACTION to the responsibility ASSET – assignements
4) Enter all functions from the LOV in the Function and Menu Exclusions
section except of the Responsibilities form except “Asset Workbench” and
“Assets:Assignments”
5) Save
6) Assign the responsibility ASSET – assignments to the appropriate user

B – Create a new menu:
1) log in as System Administrator responsibility
2) Create a new menu: Navigator: Application -> Menu      The new menu should contain only the functions and menus which should be accessible for the user.
3) Create a new responsibility       Navigator: Security -> Responsibility -> Define
4) Assign the appropriate menu to the new responsibility
5) Save
6) Assign the new responsibility to the appropriate user

Example:  Restrict a user to be able to do only Assignments in the Asset Workbench.
1) Log in with the System Administrator responsibility
2) Create the new menu menu:
Navigator: Application -> Menu
Menu: FA_ASSIGN
User Menu Name: FA Assignement
Description: FA Assignement
Seq: 1 Navigator Prompt: Assignment Function: Asset Workbench
Seq: 2 Navigator Prompt: Assignment Function: Assets:Assignements
3) Create a new responsibility: ASSET – assignments
4) Assign the menu FA_ASSIGN to the responsibility ASSET – assignements
5) Save
6) Assign the responsibility ASSET – assignments to the appropriate user
