Dear vishal sunkari,
User exits :
1. Introduction
2. How to find user exits
3. Using Project management of SAP Enhancements
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 - A user exit is a three character code that instructs the system to access a program during system processing.
SXX: S is for standard exits that are delivered by SAP. XX represents the 2-digit exit number.
UXX: U is for user exits that are defined by the user. XX represents the 2-digit exit number
An example of a user exits :-
MODULE user_exit_0001 INPUT
CASE okcode.
WHEN 'BACK OR EXIT'.
CASE sy-dynnr.
WHEN '100'.
SET SCREEN 0.
LEAVE SCREEN.
WHEN '200'.
Note that you can write any code that satisfy your needs. ****
But in this case, this was wrote as a sample code for reference sake. ****
And you can test it. ****
SET SCREEN 100.
LEAVE SCREEN.
ENDCASE.
ENDCASE.
A small search on SDN SD forum will help you to answer your query.
I will suggest you to visit http://sap-img.com/sap-sd.htm. It will give you the overview of SAP SD module.
Moreover there is a separate section of FAQs with answers which will help you in great deal.
Hope this helps you.
