Hi,

User exits are predefined includes provided by SAP with some subroutines that start with "userexit-" you can put your code in these subroutines so that they are executed.

AND

Customer exits (Function module exits) are exits developed by SAP. The exit is implementerd as a call to a function module. 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>

To find a Exit.

Goto Transaction -- Find The Package

SMOD ~~>f4~~>Use the Package here to Find the Exits In the Package.

Else if you Want to search by Application Area wise ,

There is one more tab to find the Exits in the Respective Application Area.

Implementing the Exit-- CMOD ~~Create Projects~~Assgn your Component .

Now Run ur Transaction to Check if it Triggers.

Thats it..

Suppose you need to find out all the user exits related to a tcode.

1. Execute the Tcode.

2. Open the SAP program.

3. Get the Development Class.

4. Execute Tcode SE84.

5. Open the Node 'Envir. -> Exit Techniques -> 'Customer Exits -> Enhancements'

6. Enter the Development class and execute.

Check out this thread..

1. Type the transaction : system->status-> <PROG. NAME>

2 open SE37 , type EXIT<PROG NAME> and press F4 to get the list of function exits available.

3. Open CMOD utilities->SAP enhancements

EDIT->All selections

4.type the function module name obtained in step 2, in fields 'component name' in 'additional selections' block. and execute.

5. The displayed list contains the enhancements names for the transaction You were looking for.

6. Create a project in CMOD and the code in default include->activate.

which gives the list of exits for a tcode

Hi Tanuj,

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.

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.

- 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"

The exit calls function module EXIT_SAPMV45A_003

Hi,

THe role of ABAPers is to find out the Userexit's that are available in a transaction for which you want to Enhance the functionality and then provide your code in the INLCUDE's subroutines which will be executed when you activate your subroutines and include.

ABAPer's role is to identiy the functional enhancement that they need and then code it in the userexit.

Regrds,

Sesh

Hi Tanuj,

You can go to IMG ->Sales and Distribution - > System Modifications -> User Exits .Read documentation and select in which area you are looking for a user exit.

You can also run SE84 (need pakage as selection field, 'VA' for SD) to find

out what relevant enhancements is available for SD in the system
