Hi Friends,

Difference between userexits and cuxtome exits?. Rewards are helpful answers.

Thanks,

What is User Exits and Customer Exits?

Difference between user exits & customer exits:

User exit - 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

Customer exit - The R/3 enhancement concept allows you to add your own functionality to SAP’s 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. *-- Mani

SAP creates user 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.

Types of Exits

There are several different types of user exits. Each of these exits acts as hooks where you can attach or "hang" your own add-ons.

Menu Exits

Menu exits add items to the pulldown menus in standard SAP applications. You can use these menu items to call up your own screens or to trigger entire add-on applications.

SAP creates menu exits by defining special menu items in the Menu Painter. These special entries have function codes that begin with "+" (a plus sign). You specify the menu item’s text when activating the item in an add-on project.

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

Function module exits add functions to R/3 applications. Function module exits play a role in both menu and screen exits.

When you add a new menu item to a standard pull down menu, you use a function module exit to define the actions that should take place once your menu is activated.

Function module exits also control the data flow between standard programs and screen exit fields. SAP application developers create function module exits by writing calls to customer functions into the source code of standard R/3 programs.

These calls have the following syntax:

CALL CUSTOMER-FUNCTION ‘001’.

Field Exits

Field exits allow you to create your own programming logic for any data element in the Dictionary. You can use this logic to carry out checks, conversions, or business-related processing for any screen field. Example: The data element BBBNR identifies a company’s international location number. You might want to set up your R/3 System so that all international location numbers are larger than 100.

The field exit concept lets you create a special function module that contains this logic.

You assign the special function module to the data element BBBNR. You then assign the module to any programs and screens in which users can add new international location numbers. When you activate your field exit, the system automatically triggers your special routine whenever a user enters a company location number.

In 4.6c, you can use "RSMODPRF" program to create field exits.

An example of a user exits :-

MODULE user_exit_0001 INPUT

CASE okcode.

WHEN 'BACK OR EXIT'.

CASE sy-dynnr.

WHEN '100'.

SET SCREEN 0.

LEAVE SCREEN.

WHEN '200'.

******************************************************************************

Note that you can write any code that satisfy your needs. ****
But in this case, this was wrote as a sample code for reference sake. ****
And you can test it. ****

SET SCREEN 100.

LEAVE SCREEN.

ENDCASE.

There is no difference. They're different names for the same thing.

hi,

Enhancements

The standard applications do not offer some of the functionality you need. The R/3 enchancement concept allows you to add your own functionality to SAP's standard business applications.

Different types of enhancements

Enhancements using customer exits

Customers' potential requirements which are not included in the standard software are incorporated in the standard as empty modification 'shells'. Customers can then fill these with their own coding. Enhancements can relate to programs, menus and screens. Upward compatibility is assured. In other words, SAP guarantees that the jump from the standard software to the exit and the interface which call the exit will remain valid in future releases.

Enhancements to ABAP/4 Dictionary elements

These are ABAP/4 Dictionary enhancements (creation of table appends), text enhancements (customer-specific key words and documentation for data elements) and field exits (creation of additional coding for data elements).

advantages of enhancements

Do not affect standard SAP source code

Do not affect software upgrades

Various types of customer exits

Menu exits

Screen exits

Function module exits

Keyword exits

Menu exit

Adding items to the pulldown menus in standard R/3 applications .

Screen exit

Adding fields to the screens within R/3 applications. SAP creates screen exits by placing special subscreen areas within a standard R/3 screen and calling a customer subscreen from within the standard dynpro's flow logic.

Function module exit

Adding functionality to R/3 applications. Function module exits play a role in both menu and screen exits.

keyword exit

Add documentation to the data elements of key words defined in the ABAP/4 Dictionary. The system displays this documentation whenever a user presses F1 to get online help for a screen field

Hope this helps, Do reward.

Hi,

User Exits are in the form of subroutines.They need access key(modification) to implement.There is no classifcation of user exits.

You need to redo during upgrdation.

Customer Exits includes Function Module exits , Screen Exits , Menu Exits , Field Exits.There is no need of access key(Enhancement) and no need of worry during upgradation.

But most of the people call customer exits as user exits.

Madhu.
