hi go through the following document u will get an idea

Enhancement :

represent potential customer requirements that have      not been developed in the standard. Instead, the standard provides for further development of such exits at the customer site, using logic specific to the customer.
It can be done using 
  Customer Exits
  Business ADD-Ins

Why user exits

they do not affect SAP source code but allow to change the functionality of SAP to suit your needs. SAP has provided us with standard exits that we should modify by adding your own functionality to them.
 they are named according to the naming convention they do not affect future upgrades

SAP Programs call Repository objects that you as a customer have created/changed.

Enhancement can be done at the following levels

In ABAP programs( function module exits)

On GUI interfaces (menu exits)

On screens by inserting a subscreen in an area specified by SAP (screen exits)

WHAT IS AN BADI?

BADI - Business Add-Ins
Business Add-Ins are a new SAP enhancement technique based on ABAP Objects.
Each Business Add-In has :
u2013 at least one Business Add-In definition
u2013 a Business Add-In interface
u2013 a Business Add-In class that implements the interface
   BADI is an exit point in a source that allows specific industry sectors, partners, and customers to attach additional software to standard SAP source code with out modifying the original object.
When you define a Business Add-In, enhancement management generates a class that implements your interface. 
The adapter class methods generated by add-in management decide if multiple active implementations should be called. If necessary, these implementations are subsequently executed

Advantages of BADIu2019s

This enhancement technique has the advantage of being based on a multi-level system landscape (SAP, country versions, IS solutions, partner, customer and so on).
We can create definitions and implementations of business add-ins at any level of the system landscape

Difference between customer exits and BAdiu2019s

Customer exits assume a two-tiered system infrastructure (SAP - Customers). Where as in case of BAdiu2019s you can create and implement enhancements in as many software layers as you like.

BAdiu2019s can be used to bundle program, menu and screen enhancements into a single add-in. BAdiu2019s can be created and employed in each of the various software levels.

Hi Rohan,

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 points if helpful
