Hi
User exit: It will be done with the help of a subroutine, Perform.
to know, if any screen is having user exit, go to system->status->program->search for perform user-exit.
Customer exit: Enhancements - Table exit, Screen exit, Function exit, Menu exit.
BADI
these are the Customer exits.
Customer exit means adding an additional functionality to the existing application.
1. Customer exits: Implemented as Function Modules within z includes. Anybody can change it and no access key is required.
2. User Exit: Implemented as subroutines within includes (any include except y or z includes). You need access for the specific include and then you can any subroutine (user exit) within that Include.
BADIs are the enhanced version of user exits where the same logic is implemented via classes and object (OOP)
Enchancement point is the latest once introduces with ECC6.0 . Not very sure about that but you can change it without any access key.
Please go through the following link which will help you understand the exits in a much better way:

1. Previously there were only user-exits.
2. Then came the concept of customer-exits.
3. user exits were nothing but subroutines
FORM/PERFORM
called from standard programs.
4. The FORM defintion was placed inside
an empty include file.
5. So It was called EVERYTIME.
and we need to MODIFY/REPAIR the
standard include .
6. Then it came with concept of customer-exit
7. It consists of calling a FUNCTION MODULE,
which is called only if
the user-exit is ACTIVATED (other wise not called)
In this case, the code in put inside
a pre-defined Z include.
8. Functionality of both is same, howerver
we can note the following important differences
a) Customer exit is called only if activated.
(hence, it does not waste resources)
b) in customer exit, REPAIR does not happen
to the standard include.
Exits are basically the hooks whcih SAP has provided to add your own code.
Reward if helpful.
