By default my Requisitions page opens to the View 'All My Requisitions'. I can change it to 'My Group's Requisitions'>Go and it will show all requisitions....
You can also click Search. By Default your name shows in the 'Requisition Created By' field, you can clear that open to search for other requestors.
My screen is quite different from what you are mentioning.
Can you please provide me the screen shots.
