Hi Sri,

Generally, In Enhancements There are two types of exits. They are User Exits and Customer Exits.

User Exits are standard exits delivered by SAP. By these exits we will changing the Standard programs.

Where as this customer exits are again divided into:

1. Menu Exits.

2. Field Exits.

3. Screen Exits.

4. Function module exits.

These all the things comes under Enhancements.

User exits

1.A user exit is a three character code that instructs the system to access a program during system processing.SXX: S is for standard exits that are delivered by SAP.

XX represents the 2-digit exit number.UXX: U is for user exits that are defined by the user. XX represents the 2-digit exit number

2.USER EXITS are FORMS and are called by SAP standard programs

using PERFORM.

3.Inside the form (user exit) you can read and change almost

any global data from host program.

4. User exits are more flexible because you have more information to use in your code but on the other hand , it is very easy to manipulate erroneously global data and lead the standard program to a dump or even to make database inconsistent.

5.While changing User-exit,Access Key is required,

Customer exits

1. The R/3 enhancement concept allows you to add your own functionality to SAPu2019s standard business applications without having to modify the original applications. SAP creates customer exits for specific programs, screens, and menus within standard R/3 applications. These exits do not contain any functionality. Instead, the customer exits act as hooks. You can hang your own add-on functionality onto these hooks.

2.CUSTOMER EXITS are FUNCTIONS so they are called using CALL

FUNCTION (or more exactly CALL CUSTOMER FUNCTION).

3.Inside a function (customer exit) you can only acces your import/export/changing/tables parameters.

4.Customer exits are more restrictive but you are sure any change you can make to any parameters will never lead to inconsistency

5.in Customer-exit no access key is needed.

Reward points if useful.
