Hi,
To Enhance any standard compoenent, and specially a "VIEW" just follow the below steps:
1. Go to SE80, Give the Component Name and press Enter
2. Go to the Desired "View"
3. Click enhance button (ICON Like spiral,6th from left to right of Application toolbar)
4. A Pop up will appear asking your Coposite Enhancement name  and Enhancement Implementation name. Create "NEW" on both the occasion.
Now for UI Enhancements:
a) Click the "ROOT UI Element container" , right click add the custom UI elements and assign Property values as per your requirement( like binding,text,action etc.,). It is just like adding UI elements in Z-Compoent.
b) Create actions wherevr required
For Coding Level enhancements:
Here, for all the methods which are in the standard compoenent will have "PRE" and "POST" Exits. The difference is "PRE" Exits will render before calling the actual code and "POST" Exit will render after rendering the actual code.
Note: Till Enhancement Pack (EHP3) we had only PRE & POST Exits. And Now on from EHP 4 and More we do have an option "OVER WRITE" Exit.
Apart from Exits, we can create our own Events/event Handlers. These Event Handlers will work only for the enhancements.
We Can write our own logic in the newly created event/event handler.
