topic hi in Application Development and Automation Discussions

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_<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 i 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"

hiii

User Exit ia a code that will instruct the syatem to access program.

There are 4 types of use exit 1.Menu Exit 2.Screen Exit 3.Field Exit 4.function Module Exit

By using Menu Exit we can create our own menu can say additional features of menu in menu painter.It will give effect on selection screen.

By using Screen Exit we can create some more elements on screen as per our requirement.suppose there are 3 input fields on screen & i want one more field in screen then we can do it by using screen exit.

By using function module exit we write a code for whatever we have added by using menu exit & screen exit.

Field exits allow you to create your own programming logic for any data element in the Dictionary. Example: The data element carrid identifies a carrier id. You want to change it so that all numbers are larger than 10.then you can write function module for that & just need to assign it to that field. Thus by using it we can give our own type of field to the screen with our own validation.

reward if useful

thx
