New to sap enhancements..

Take this program into your sap, try with a transaction. when you click on the exit name you will go in the transaction where you can test.

(trans: SMOD, CMOD)

REPORT  zz_recherche_user_exit NO STANDARD PAGE HEADING.

* 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.

Hi,

Go through this documentation to get an idea of user eixts.

Hi,

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. Customer exits are not available for all programs and screens found in R/3 standard applications. You can only use customer exits if they already exist in the R/3 System.

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 <3 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

<b>How to find user exits</b>

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.

OR u can use the above program which will give u a list of all the user exuts available.
