HI

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"

User exit is used to customise standard sap programs. It is like a hook or blank templet provided by SAP for that purpose. In thatblank templet you can attach your code to solve a specific purpose which is not provided by SAP standard programs. You and also achieve the same by appling a access key and change the sap standard program but the disadvantage with that when sap will come with a new version they will not take are your modification. so it is always good practice to use enhancements like user exits. you can un attached those exits when you need just like a hook. there are mainly three type of exits.

1. Functional module exits : to change the standard code

2. Screen exits : To change the standard screen

3. Menu exits: To change the standard menu

now, screen and menu exits can not work alone alwyas there will be a specific FM exits attached with those exits where you will code for that perticular menu enhancement or screen enhancement.

most of the user exits (MM,PP) are found and coded in transaction SMOD & CMOD. But SD user exits are generally not found in those transactions. They are directly attached with the mail standard program. So you need access key to change those exits.
