Self-Service Personalizations

I'm trying to do a function-level personalization for the Personal Information function within Employee Self-Service.

I've copied the function and changed the function name at the end so that it equals: OA.jsp?akRegionCode=HR_CREATE_PROCESS_TOP_SS&akRegionApplicationId=800&OAFunc=XXMY_FUNCTION_NAME

I've left the parameters the same.

The problem is, when I add XXMY_FUNCTION_NAME to the Employee Self Service menu as a seperate function, it still seems to load up the same Personal Information function so my function-level personalization does not work.

Does anyone have any ideas where I might be going wrong?

Thanks
