Hi,

SAP delivers a broad range of business functions within its R/3 application suite. The standard applications may not offer some of the functionality needed. The R/3 enhancement concept allows addition of one’s own functionality to SAP’s standard business applications.

SAP creates user exits for specific programs, screens and menus within standard R/3 applications. These exits do not contain any functionality. Instead, the user exits act as hooks. One can hang his own add-on functionality onto these hooks.

The user exit is a point in a SAP program where a customer’s own program can be called. On upgrade, each user exit must be checked to ensure that it conforms to the standard system.

There are three types of exits:

Menu Exits

Screen Exits

Function module Exits

MENU EXITS

1.Menu exits allow you to attach your own processes to action menu items. For this, the SAP applications programmer reserves certain menu entries in the GUI interface.

2.The Menu exit entries have function codes that begin with + (Plus sign).

3.Once you activate the menu exits, they become visible in the application. When the menu item is selected, either the functionality provided by the SAP applications programmer or your own functionality implemented in the program exit is processed.

Screen Exits

Screen exits add fields to screens in R/3 applications. SAP creates screen exits by placing special subscreen areas on a standard R/3 screen and calling a customer subscreen from the standard screen’s flow logic.

Function module Exits

1.Function module exits allow you, as customer, to implement additional logic in an application function. The SAP applications programmer defines where in the application function the function module exits are placed and which data is to be transferred. The programmer also creates the related function modules with short text, interface, and documentation and describes the intended functionality of the function module exit in the SAP documentation.

2.You code the function modules, and if needed the screens, text elements, and your own Includes for the function group.

3.After you activate the enhancement project that contains the function module as component the ABAP/4 code will be processed. Before that, the program exits have no effect.

Reward if it helps..
