Hi dharmesh,

1. In sap transactions/prgrams,

they have provide POINTS

a) at the time of display data

b) at the time of saving data

c) etc.

where they call some FM.

In this FM we can write our customer

code to do some validations etc.

This is called USER-EXIT.

2.How to find userexist?

Use SMOD tcode

How to Implement in SAP Application?

We can only implement

if the sap program provides the POINTS

Other wise not.

If it provides, then we can use CMOD(to make a new project)

and enhance it using the name of the user-exit.

regards,

amit m.

Hi Dharmesh,

SAP Provides a include file where u can add extra functionality to the existing applications. This can be done thru the user-exists...where the user can add the xtra functionality required.

For every standard applicaton there exists a user-exit. u can search the user-exist in transaction SMOD.

After searching the required exit. u can modify/add the code thru transaction CMOD.

Hi Dharmesh,

User exits are empty subroutines that SAP developers have provided for you.YOu can fill them with your own source code.You can search for user exit using "PERFORM userexit_" in main program of a transaction..

1. 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.

2. How to find user exits and to implement.

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.

Hi,

check out these links:

Finding the user-exits of a SAP transaction code
*
* Enter the transaction code in which you are looking for the user-exit
* and it will list you the list of user-exits in the transaction code.
* Also a drill down is possible which will help you to branch to SMOD.

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

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.

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 i 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.

Hi Dharmesh,

1. USER EXITS are FORMS and are called by SAP standard programs using PERFORM.

2. Inside the form (user exit) you can read and change almost any global data from host program.

3.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.

4.User-exit doesn’t have any classification.

5.User Exits are Basically designed For SD module.

6. User-exits can be written only using access-key.

7.With user-exits the code , the developer has written will not be there for next version unless modification assistance tool is used.
