user-exit

Former Member — Sat, 18 Nov 2006 10:19:48 GMT

I neve touched user-exits in real scenario.

Even though i have documents ..but confused where to start.

What is SMOD and CMOD?Where exactly we insert our code?

As far my knowledge i have to find exit for VA01.

Then i go for CMOD and there i find EXIT_***,then i come to se37 and give this FM name and click on Include and make the changes??is above process right?

Then why do we want SMOD?and why people worry how to find an Exit?and how we can find EXIT for specific TCODE(ex va01)?

How do we link this exit to VA01?

"EXIT_SAPL1022_001"---do we call this is an Exit??

suppose if we know EXIT corresponsing to VA01,then from where we start?where does packages comes to picture and why developement class?

Please avoid my confusion?

Thanks in advance

Hi,

First use the following code to get all user exits for a given transaction.

Select the Correct enhancement.

Then in SMOD, decide the component which u wanna use.

Go to that function module, create the Z include which u see there.

Write ur code in that include.

Now u need to assign ur enhancement to a project in CMOD.

Create a new Project there, & in enhancement assignments, give ur enhancement name & activate.

From here the system detects ur enhancement whenever u run the transaction.

report z_user_exit no standard page heading.

CMOD is the Project Management of SAP Enhancements (i.e., SMOD Enhancements). SMOD contains the actual enhancements and CMOD is the grouping of those SMOD enhancements.

User 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 function module 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 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

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.

Using Project management of SAP Enhancements

You want to create a project to enhance transaction 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 for 1 project. If the enhancement is allready 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 create a salesorder. Note that Sold-to-party now automatically is "2155"

All the exits related to one transaction are generally stored in one development class.

I hope it helps.

Hi Vibha

Thanks for your answer.

I still have some doubts in that..

SAPMV45A is the program for VA01.

Iin program SAPMV45A ,do i need to search for CALL CUSTOMER-FUNCTION '003'?

once i found this CALL CUSTOMER-FUNCTION '003',what shud be the next step?

where shud i get EXIT_PRGNAME??

in every transaction,this CALL will be there>

Please provide me the steps if posible?

Thanks

Trx CMOD/SMOD are to manage the user-exit defined as CUSTOMER FUNCTION, but some trxs use different kinds of user-exit.

The trx VA01, i.e. the program SAPMV45A uses some routine defined in the include MV45AFZ* (see MV45AFZA, MV45AFZB, MV45AFZZ).

U need to access key if you want to develop a routine, because u'll change a standard include.

once u reach here ..

CALL CUSTOMER-FUNCTION '003'

double click on '003'

this will lead u to a function module exit_XXX

3. u will find a include ZXXXXX.

4. double click on ZXXXXX include

in here u need to write the code .

acitivate it ..

activate in cmod .

In VA01/VA02 there are other kind of includes also and there u can add your functionality. To get more details abt the exits related to VA01/VA02, have a look at below link.
