Please read through the following,

A. 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 written 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>


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):



xvbak = vbak

xvbuk = vbuk

xkomk = tkomk


lvf_subrc = lvf_subrc


xvbfa = xvbfa

xvbap = xvbap

xvbup = xvbup.

The exit calls function module EXIT_SAPMV45A_003

B. How to find user exits?


There are 3 main ways to find exits

1) Option 1 : you don't know the name or dont have any info on user exit


run T-code : SPRO

SPRO -> Click SAP Reference IMG -> click in the relevant module eg: SD (sales and Distribution) ->System Modifications -> User exits

You can view documentation to understand the purpose of that user exit

It is not that always one can find the user exits under the name "System modifications" but with respect to a module definitely user exits can be found under that module in SPRO

OR you know the program in which exit needs to be trigerred

se38 ->enter standard program name -> click display ->

search -> in the search box CALL CUSTOMER (in main program)

if you find anything,this is the function module which will call for your exit

Please remember that SAP uses many programs for running a standard t-code and

hence may use many programs...pls reconfirm if the user exits are available using a sample program given below

2) Option 2 : You know the name of the user exit


Run Tcode : SMOD -> fill in the enhancement name-> click on attributes and then components or directly on components and view the include...if already a code is written in the include,then on double click of include you can see the code...if an existing code is not there and you double click on the include,SAP prompts for a request

3)Option3: You can use the custom code..which was contributed to SDN


Create a new report program -> copy the code -> activate -> run

on the p_tcode : give the name of the tcode for which you need to find the user exits and execute...a list of exits will be displayed...double click and follow the link
