user exit

Hi

What is user exit? Give me few scenarios where user exit can be used.

thanks in advance

1.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"

Types of Exits

There are several different types of user exits. Each of these exits acts as hooks where you can attach or "hang" your own add-ons.

Menu Exits

Menu exits add items to the pulldown menus in standard SAP applications. You can use these menu items to call up your own screens or to trigger entire add-on applications.

SAP creates menu exits by defining special menu items in the Menu Painter. These special entries have function codes that begin with "+" (a plus sign). You specify the menu item’s text when activating the item in an add-on project.

Screen Exits

Screen exits add fields to screens in R/3 applications. SAP creates screen exits by placing special subscreen areas on a standard R/3 screen and calling a customer subscreen from the standard screen’s flow logic.

Function Module Exits

Function module exits add functions to R/3 applications. Function module exits play a role in both menu and screen exits.

When you add a new menu item to a standard pull down menu, you use a function module exit to define the actions that should take place once your menu is activated.

Function module exits also control the data flow between standard programs and screen exit fields. SAP application developers create function module exits by writing calls to customer functions into the source code of standard R/3 programs.

These calls have the following syntax:

CALL CUSTOMER-FUNCTION ‘001’.

Field Exits

Field exits allow you to create your own programming logic for any data element in the Dictionary. You can use this logic to carry out checks, conversions, or business-related processing for any screen field. Example: The data element BBBNR identifies a company’s international location number. You might want to set up your R/3 System so that all international location numbers are larger than 100.

The field exit concept lets you create a special function module that contains this logic.

You assign the special function module to the data element BBBNR. You then assign the module to any programs and screens in which users can add new international location numbers. When you activate your field exit, the system automatically triggers your special routine whenever a user enters a company location number.

1. Introduction:

hi

Userxits allow us to add our own functionality to SAP standard program

without modifying it . These are implemented in the form of subroutines and hence are also known as FORM EXITs. The userexits are generally collected in includes and attached to the standard program by the SAP.

Types of User exits

1. Menu Exits

2.Function exits

3.Table exits

4.Screen exits

5.Keyword exits

6.Field exits.

User exits for Pricing.

1.•USEREXIT_PRICING_PREPARE_TKOMK (module pool SAPLV60A, program RV60AFZZ

2.•USEREXIT_PRICING_PREPARE_TKOMP (module pool SAPLV60A, program RV60AFZZ)

3.•USEREXIT_FIELD_MODIFICATION

4.•USEREXIT_FIELD_MODIFIC_KZWI

5.•USEREXIT_FIELD_MODIFIC_KOPF

User exits for Sales order

1•USEREXIT_DELETE_DOCUMENT

2•USEREXIT_FIELD_MODIFICATION

3.•USEREXIT_MOVE_FIELD_TO_VBAK

4.•USEREXIT_NUMBER_RANGE

5.•USEREXIT_SAVE_DOCUMENT

User exits for billing

1.•USEREXIT_ACCOUNT_PREP_KOMKCV (Module pool SAPLV60A, program RV60AFZZ)

2.•USEREXIT_ACCOUNT_PREP_KOMPCV

3•USEREXIT_NUMBER_RANGE_INV_DATE (Module pool SAPLV60A, program RV60AFZC)

4•USEREXIT_PRINT_ITEM (Module pool SAPLV61A, program RV61AFZB

5.USEREXIT_PRINT_HEAD (Modulpool SAPLV61A, Programm RV61AFZB)

User exits in the SD orders. These are program names (SE38):

MV45ATZZ

For entering metadata for sales document processing. User-specific

metadata must start with "ZZ".

MV45AOZZ

For entering additional installation-specific modules for sales

document processing which are called up by the screen and run under

PBO (Process Before Output) prior to output of the screen. The

modules must start with "ZZ".

MV45AIZZ

For entering additional installation-specific modules for sales

document processing. These are called up by the screen and run under

PAI (Process after Input) after data input (for example, data

validation). The User exits in the SD orders. These are program names (SE38):

MV45ATZZ

For entering metadata for sales document processing. User-specific

metadata must start with "ZZ".

MV45AOZZ

For entering additional installation-specific modules for sales

document processing which are called up by the screen and run under

MV45AIZZ

For entering additional installation-specific modules for sales

document processing. These are called up by the screen and run under

PAI (Process after Input) after data input (for example, data

validation). The modules must start with "ZZ".

MV45AFZZ and MV45EFZ1

for entering installation-specific FORM routines and for using user

exits, which may be required and can be used if necessary. These

program components are called up by the modules in MV45AOZZ or

MV45AIZZ. e modules must start with "ZZ".

MV45AFZZ and MV45EFZ1

for entering installation-specific FORM routines and for using user

exits, which may be required and can be used if necessary. These

program components are called up by the modules in MV45AOZZ or

MV45AIZZ.

SMOD is the transaction to view user exits assigned to an object.

CMOD is the transaction to change the user exits according to your requirement.

refer to the link below and the below info might be of some help..

http://www.planetsap.com/userexit_main_page.htm

u can also view the list of user exits by

Tcode: <b>CMOD</b>> <b>Utilities</b>> <b>Sap Enhancements</b>> <b>Execute (F8)</b>

Reward if USeful

Thanx & regards.
