Hai,

Userxits allow us to add our own functionality to SAP standard program

without modifying it . These are implemented in the form of subroutines and hence are also known as FORM EXITs. The userexits are generally collected in includes and attached to the standard program by the SAP.

User exits are used when the flow for a particular transaction has to take some other route other then the normal flow. this can be the case when you have to attach some additional functionality lik u need a customised screen, or new functionality (using a functional module). based on these things user exits can be classified as screen exits, function module exits, field exits( not used anymore). hope this gives some help on userexits.

For More information on Exits, check these links

User exit - A user exit is a three character code that instructs the system to access a program during system processing.

U is for user exits that are defined by the user.

SAP uses an User Exit (SMOD/CMOD) in order to make an enhancement of customers a lot more convenient. There are very many user exits available within SAP.

When using an user exit, the system does NOT become modified what happens when you start changing SAP for your needs.

So, it is very interesting to make use of all options, that leave the SAP system as unmodified as possible. Therefore, you should always check the available user exits in the area for your needed enhancements.

You can activate user exits in the SAP transactions SMOD and CMOD. There you can check for the appropiate user exit and insert the new enhanced code in function modules for your needs.

Hi SHNYA,

User exits :

1. Introduction

2. How to find user exits

3. Using Project management of SAP Enhancements

1. Introduction:

User exits (Function module exits) are exits developed by SAP. The exit is implementerd as a call to a functionmodule. The code for the function module is writeen by the developer. You are not writing the code directly in the function module, but in the include that is implemented in the function module.

The naming standard of function modules for functionmodule exits is:

EXIT_<program name><3 digit suffix>

The call to a functionmodule exit is implemented as:

CALL CUSTOMER.-FUNCTION ❤️ digit suffix>

Example:

The program for transaction VA01 Create salesorder is SAPMV45A

If you search for CALL CUSTOMER-FUNCTION i program

SAPMV45A you will find ( Among other user exits):

CALL CUSTOMER-FUNCTION '003'

exporting

xvbak = vbak

xvbuk = vbuk

xkomk = tkomk

importing

lvf_subrc = lvf_subrc

tables

xvbfa = xvbfa

xvbap = xvbap

xvbup = xvbup.

The exit calls function module EXIT_SAPMV45A_003

2. How to find user exits? Display the program where you are searching for and exit and search for CALL CUSTOMER-EXIT

If you know the Exit name, go to transaction CMOD.

Choose menu Utillities->SAP Enhancements. Enter the exit name and press enter.

You will now come to a screen that shows the function module exits for the exit.

3. Using Project management of SAP Enhancements, we want to create a project to enahance trasnaction VA01 .

- Go to transaction CMOD

- Create a project called ZVA01

- Choose the Enhancement assign radio button and press the Change button

In the first column enter V45A0002 Predefine sold-to party in sales document.

Note that an enhancement can only be used in 1 project. If the enhancement is already in use, and error message will be displayed

Press Save

Press Components. You can now see that enhancement uses user exit EXIT_SAPMV45A_002. Double click on the exit.

Now the function module is displayed. Double click on include ZXVVAU04 in the function module

Insert the following code into the include: E_KUNNR = '2155'.

Activate the include program. Go back to CMOD and activate the project.

Goto transaction VA01 and craete a salesorder.

Note that Sold-to-party now automatically is "2155"

Younus
