Hi Supraja,

User exits are the enhancements provided by SAP

you can use them in transactions. Each transaction will have user exits.

If you want to use your own requirements by making your coding while the transaction is run you can use user exits.

For example if you want to run the MRP in MD02 specific to MRP controller you can user exit.

Please also refer the document below.

USEREXIT

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.

All Userexits start with the word USEREXIT_...

FORM USEREXIT_..

z..

ENDFORM.

The problem lies in finding the correct userexit and how to find it if one exists for the purpose. Once the correct userexit is found the necessary customer code is inserted in the customer include starting with the z. in the form routine.

e.g. USEREXIT_SAVE_DOCUMENT_PREPARE

Certain application like SD still provide this form of enhancement using userexit but this practice is no longer being followed for newer extensions instead they are using EXITs which come bundled in enhancement packages . Nevertheless existing USEREXITS will be supported by SAP an all the newer versions of SAP.

HOW TO FIND USEREXITS

Userexits can be found in number of ways:

1) To find userexits in SD module , goto object navigator(SE80) and select

development class from the list and enter VMOD in it. All of the userexits in SD are contained in the development class VMOD. Press enter and you will find all the includes which contain userexits in SD for different functions like PRICING, ORDER PROCESSING etc. Select the userexit according to the requirement and read the comment inserted in it and start coding.

Some examples of userexits in SD (SALES & DISTRIBUTION) are:

1)ADDING OF NEW FIELDS IN PRICING

In Pricing in SD the fields on the basis of which pricing is done are derived from the FIELD CATALOG which is a structure KOMG .This structure is used to transfer transaction data to the pricing procedure in SD and is also known as communication structure. This structure KOMG consists of two tables KOMK for Header related fields and KOMP for item related fields. The fields which are not in either of the two tables KOMK and KOMP cannot be used in pricing .Sometimes a need arises when the pricing is to be based on some other criteria which is not present in the form of fields in either of the two tables. This problem can be solved by using USEREXITS which are provided for pricing in SD. Pricing takes place both when the SALES ORDER ( Transaction VA01) is created as well as when INVOICING ( Transaction VF01) is done. Hence SAP provides 2 userexits ,one for sales order processing which is

USEREXIT_PRICING_PREPARE_TKOMP or

USEREXIT_PRICING_PREPARE_TKOMK

Depending upon which table (KOMK or KOMP) the new fields were inserted we use either of the above two userexits.These userexits are found in include MV45AFZZ of the standard SAP sales order creation program SAPMV45A.

In the case of userexit which will be called when invoicing is done ,these

are provided in the include RY60AFZZ which is in the standard SAP program SAPMV45A. The name of the userexits are same. i.e.

USEREXIT_PRICING_PREPARE_TKOMP or

USEREXIT_PRICING_PREPARE_TKOMK

These userexits are used for passing the data from the communication structure to the pricing procedure, for this we have to fill the newly created field in the communication structure KOMG for this we fill the code in the above userexit using the MOVE statement after the data that has to be passed is taken from the database table by using the SELECT statement. The actual structure which is visible in these userexits and which is to be filled for that particular field is TKOMP or TKOMK.

Before the coding for these userexits is done ,it is necessary to create a new field in either of the two tables KOMK or KOMP .For this purpose includes are provided in each of them .

To create the field in header data (KOMK) the include provided is KOMKAZ

and to create the field in item data (KOMP) the include provided is KOMPAZ.

One possible example for the need of creating new fields can be e.g. Freight to be based upon transportation zone, for this no field is available in field catalog and hence it can be created in KOMK and then above userexits can be used to fill the transportation data to it.

2) The other method of finding userexit is to find the word USEREXIT in the

associated program of the transaction for which we want to determine userexit using SE38.

3) The other method of finding userexits is to find the include in case of SD/MM applications where the userexits are located, this can be found in the SAP reference IMG generally in the subfolder under SYSTEM MODIFICATION.

Some other examples of userexits in SD are:

USEREXIT_NUMBER_RANGE

This userexit is used to assign a different internal document number to the

sales order(VA01) when it is created depending on some criteria like a different SALES ORGANIZAION(VKORG) .

USEREXIT_SAVE_DOCUMENT_PREPARE

This userexit is used to insert the ABAP code which will be called when

the document (sales order VA01) is just about to be saved. This userexit is used generally for custom checks on different fields , to display some information before the order will be saved or for making changes to certain fields before the sales order will be saved.

Exits & Enhancements

There are mainly six types of EXITs in sap which have been collected in the form of enhancement packages and attached to standard code in SAP.

These are different from USEREXIT in the way that they are implemented

in the form of FUNCTIONs while in USEREXITS we use form routines for their implementation. These are also sometimes known as function exits.

These start from the word EXIT_ followed by the program name and then followed by a three digit number.

e.g. EXIT_SAPMV45A_002

This exit is found in SD in enhancement V45A0002.

TYPES OF EXITS

1) MENU EXITS

2) FUNCTION EXITS

3) TABLE EXITS

4) SCREEN EXITS

5) KEYWORD EXITS

6) FIELD EXITS

We use SAP transactions CMOD and SMOD to manage exits. Before implementing an exit, it is required to create the project by using CMOD

selecting the enhancement e.g. V45A0002 and selecting the component

(one which fulfills our need) i.e. the exit which will be implemented in SMOD and after coding has been done the project has to be activated.

An exit can be coded only once.

FUNCTION EXITS

These are used to add functionality through ABAP code. These start from the word EXIT_programname_NNN ending in a 3 digit number. No access code is required to implement any type of exit including function exits.

The function exits are called from the standard SAP program in the form

of ABAP statement

CALL CUSTOMER-FUNCTION 'NNN'

This is in contrast to USEREXITs where PERFORM statement is used to call

the required userexit.

To implement the FUNCTION EXITs first of all the project is created and a suitable enhancement package is selected and from its components the function exit to be implemented is selected and on double clicking it the exit code will appear in ABAP EDITOR(se38) where a Z include will be found and the customer code should be entered in this include.

e.g.

ADDING A DEFAULT SOLD-TO-PARTY in Sales Order Creation

To show a default sold-to-party in this field when the user creates a sales order (VA01) we can use a function exit .This function exit is located in enhancement no V45A0002 . Before we can choose the exit we have to create a project in CMOD after that enter V45A0002 in the enhancement field and click on the components. In the components you will see the exit EXIT_SAPMV45A_002. This exit is used for our purpose.

Double clicking on this exit will takes us to function builder (SE37) . This

function exit has one exporting parameters and two importing parameters, we are interested in exporting parameter which is E_KUNNR of type KNA1-KUNNR i.e. if we move the desired customer name to this structure(E_KUNNR) it will be shown in the field as the default value when we create the sales order. This function also contains a customer include ZXVVA04. This include will be used to write our custom code.

Double clicking on this include and it will prompt us that this include does not exists do you want to create this object, select yes and the include will be created .In this include we can write our own code that will fill the field E_KUNNR.

e.g. E_KUNNR = 301.

Activate the include and Activate the project. Now when ever the SALES ORDER will be created, sold-to-party field will come up with a predefined customer.

FIELD EXITS

The field exits are managed, created, activated through program RSMODPRF. The field exit is associated with a data element existing in ABAP dictionary and hence to the screen field using that data element.

The format of field exit is:

FIELD_EXIT_dataelement_A-Z or 0-9

If a particular screen and program name is not specified than the field exit will effect all the screens containing that data element.

The function module associated with field exit shows two parameters

INPUT and OUTPUT. Input parameter contains the data passed to the field exit when the field exit was invoked by the R/3, we can write our own code to change the output parameter depending upon our requirements.

Before the field exit can have any effect the system profile parameter

ABAP/FIELDEXIT in all the application servers should be set to YES

ABAP/FIELDEXIT = YES.

TYPES OF USER EXITS

User exits are basically 4 types,

1. Field exit,

2. Menu Exit,

3. Function module and

4. Screen exit.

These exits we can use according to a situation...

hi,

SAP has provided some slots where we can define our own custom code putting the required logic to meet the customer requirements.

we can have user exits at order, delivery, billing etc. With the help of user exits we can see that the system helps us meet the customer requirements. Basically user exits are one of the varieties of enhancements.

for example you can go to SE38 and give MV45AFZZ and click display. You will all the user exits which can be used at order level. Once you go through this and you willl also understand the need for which these user exits are provided.

Thanks

Hi,

See this detailed infirmation about USER EXITS

<b>A Short Tutorial on User Exits</b>

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"

Hope this helps you

Hi

<a href="http://http://www.easymarketplace.de/userexit.php">SAP User Exits</a>

<a href="http://sapsdforum.wordpress.com/category/sd-user-exits/">SD User Exits</a>

User exits are routine which SAP allows you to add in additional customized programs process without affecting the standard SAP programs.

SAP user exit are usually declare as a form routine :-

form userexit_xxxxx

........................

endform

In VL01 - Create Delivery Order, standard program SAPMV50A, the standard program did not check for storage location equal to space, and delivery quantity less than one when the user click the save button. Therefore I have to insert the additional checking into the userexit routine.

Steps:-

  • Goto transaction VL01 to pick a Sales Order for delivery (you don't have to save the data)

  • In the initial screen, click System -> Status -> Double click on Program (Screen)

  • In the dialog program SAPMV50A, click Edit -> Search/replace

  • Type userexit in the Find field, then click the In program radio button and hit Enter

  • A number of userexit routine will be display. You'll have to roughly decide which is the correct userexit routine to used.

form userexit_save_document_prepare.

case xlips-pstyv.

when 'TAX' or 'REX'.

  • Accept this two Delivery item category

when 'REN'.

if xlips-lgort = space.

  • Reject this Delivery item category

message e001.

endif.

when others.

if xlips-matnr <> space.

  • Check storage location not space

if xlips-lgort = space.

message e002.

endif.

  • Check delivery quantity not zero

if xlips-pikmg < 1.

message e003.

endif.

endif.

endcase.

endform.

What is the use of user-exit and all?

Is it about modifying SAP program?

Suppose that you need some functionality which is not provided in sap what do you do. Sap has provided you with three options.

1) Customizing.

2) Modifications.

3) User Exits.

So what are these three in the first case when you take Customization is nothing but you are customizing SAP according to your need and requirement for example you want the Purchase Order Numbers to start with <Co_Name><seq_no>(sequential no) this kind of stuff is done in customization.

Modification is nothing but you are modifying SAP std code which is written during developing your SAP std programms or screens.

Thirdly to avoid modifications SAP has provide you with some exit points like for example after the PBO event in module pool programming comes the PAI. so in between these two events you wanted the change something so SAP has provided with an exit point. that exit point is called user exits. for example user exits for me21 PO Create is MM06005 if I am not wrong. they are nothing but simple function module within which you write your code which functions just like normal program and executes between the PAI and PBO events.
