Finding user-exit in mm01 saving

[Former Member]

Hi,

I want to use the suerexit in mm01 for saving the dataset. I googled for how to find a user exit. I read that I need to use TN cmod, but there I only see the customer projects enlisted.

What I need is where to find the user exit so (or any user exit) to start my code from there.

thank you.

Hi,

from the customer projects go to the enhancements of the projects there you will get the exits required.

Get the relevant exit by the desciption of the project.

Hi,

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

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"

Hello,

thanks for your answers.

MM01 is called SAPLMGMM.

when i dislay this programme in se38 I wont find any "CALL CUSTOMER-FUNCTION". The programm consists of includes.

These included programmes don't have that string either.

I just found this:

http://www.easymarketplace.de/userexit-de.php

It's a list showing all userexits. These are the exits from mm01:

MGA00001	Materialstamm (Industrie): Prüfungen und Erweiterungen
MGA00002	Materialstamm (Industrie): Nummernvergabe
MGA00003	Materialstamm (Industrie und Retail): Nummerndarstellung
MGV00001	Materialstamm (Industrie): ALE-Verteilung
MGV00002	Materialstamm (Industrie): Werte für Filterobjekte lesen
MGV00003	Materialstamm (Retail): ALE-Verteilung
MGW00001	Materialstamm (Retail): Zusatzdaten

| MGW00002|Materialstamm (Retail): Nummernvergabe

Now I need to find the one that is used when saving a dataset.

[Former Member]

even if I do it step by step as the tutorial you posted in va01 there I won't find CALL CUSTOMER-FUNCTION either thats all only includes.

Hi,

Step by step procedure for creating Field Exits

There are eight steps to creating a field exit:

Step 1: Determine Data Element

Step 2: Go To Field Exit Transaction

Step 3: Create Field Exit

Step 4: Create Function Module

Step 5: Code Function Module

Step 6: Activate Function Module

Step 7: Assign Program/Screen

Step 8: Activate Field Exit

Step 1: Determine Data Element

u2022 Before you can begin adding the functionality for a field exit, you must know the corresponding data element.

u2022 An easy way to determine the data element associated to a particular screen field is to:

Go the appropriate screen.

Position the cursor in the appropriate field.

Press u2018F1u2019 for field-level help.

Click on the u2018Technical infou2019 pushbutton (or press u2018F9u2019) on the help dialog box.

On this Technical Information dialog box, the data element will be specified if the field is 'painted' from the ABAP/4 Dictionary.

Step 2: Go To Field Exit Transaction

u2022 The transaction to create field exits is CMOD.

u2022 You can use the menu path Tools -> ABAP/4 Workbench -> Utilities -> Enhancements -> Project management.

u2022 From the initial screen of transaction CMOD, choose the Text enhancements -> Field exits menu path.

u2022 After choosing this menu path, you will be taken to the field exits screen. From here, you can create a field exit.

NOTE : Even though you use transaction CMOD to maintain field exits, you do not need to create a project to activate field exits.

Step 3: Create Field Exit

u2022 From the field exit screen of transaction CMOD, choose the Field exit -> Create menu path.

u2022 After choosing this menu path, a dialog box will prompt you for the appropriate data element .

u2022 Enter the data element name and click the u2018Continueu2019 pushbutton.

u2022 Now, you will be able to create the function module associated to the data elementu2019s field exit.

Step 4: Create Function Module

u2022 You will automatically be taken to the Function Library (SE37) after entering a data element name and clicking the u2018Continueu2019 pushbutton.

u2022 In the u2018Function moduleu2019 field, a function module name will be defaulted by the system based on the data element specified. This name will have the following convention:

FIELD_EXIT_

u2022 You can add an identifier (an underscore followed by a single character ).

u2022 The first function module for a data elementu2019s field exit must be created without an identifier.

u2022 To create the function module, click on the u2018Createu2019 pushbutton, choose menu path Function module -> Create, or press u2018F5u2019.

u2022 After choosing to create the function module, you will get the warning: "Function module name is reserved for SAP". This message is just a warning so a developer does not accidentally create a function module in the field exit name range. By pressing u2018Enteru2019, you will be able to go ahead and create the function module.

u2022 Before coding the function module, you will have to specify the function modules attributes -- function group, application, and short text.

Step 5: Code Function Module

u2022 From the function moduleu2019s attributes screen, click on the u2018Source codeu2019 pushbutton or choose the Goto -> Function module menu path to the code of the function module.

u2022 Here you will add your desired functionality for the field exit.

u2022 Remember that field exitu2019s function module will have two parameters -- one importing parameter called "INPUT" and one exporting parameter called "OUTPUT". These parameters will be set up automatically by the system.

u2022 You must remember to assign a value to the OUTPUT field. Even if the value does not change, it must be moved from the INPUT field to the OUTPUT field.

Step 6: Activate Function Module

u2022 After coding the function module, you must remember to activate it.

u2022 Use the Function module -> Activate menu path to activate the function module.

u2022 At this point, you can return to the field exit transaction.

u2022 You should be able to 'green arrow' back to this transaction.

u2022 When you return to the field exit transaction, you will see an entry for the newly created field exit.

u2022 At this point, the field exit is global. That is, it applies to all screens that use a particular data element. On any screen that uses the data element, the corresponding field exit function module will be triggered, once it is active.

u2022 Also, the field exit will not be triggered yet because it is inactive.

Step 7: Assign Program/Screen

u2022 This step is only needed if you want to make a field exit local.

u2022 To make a field exit local, select the field exit and click on the u2018Assign prog./screenu2019 pushbutton.

u2022 In the dialog box , indicate the appropriate program name and screen number.

This information indicates that the field exit is local to the specified screen in the specified program.

u2022 In the dialog box, you determine which function module gets executed for the field exit by specifying the identifier in the u2018Fld. Exitu2019 field.

u2022 If this field is left blank, the function module triggered will be 'FIELD_EXIT_'.

u2022 If a single-character identifier is entered into the field, the function module triggered will be 'FIELD_EXIT__'.

Step 8: Activate Field Exit

u2022 The field exit must be active for it to be triggered by the system.

u2022 Activate the field exit by choosing the Field exit -> Activate menu path.

u2022 After assigning the field exit to a change request, its status will change to u2018Activeu2019 and it will be triggered automatically on the appropriate screen(s).

NOTE : In order to activate the field exit the profile parameter abap/fieldexit = YES must be set on all application servers

Step by step procdure for creating Menu Exits

PART A: Search for the menu exit.

1. A menu exit is a way to add a menu item and corresponding functionality to the menu bar of an SAP transaction. The first step is to navigate to the screen where you want to attach menu exit.

2. Go to the menu painter of that screen through system -> status and look for function codes in the menu bar that start with a plus sign. These are the menu's which can be enhanced.

PART B: Attaching your own menu.

3. Run transaction YSMD (available in 3.1G) to identify the Enhancement and the Component which contains that exit or search it through transaction SMOD.

Note : All menu exits will have the function code name with the plus sign as the last four characters of the component.

4. Include the Enhancement in your own project through transaction CMOD.

5. Go to Enhancement Components a

And double click on the component name to give your own text to the menu item.

6. Activate the project.

At this point the menu item will appear, but it will have no functionality.

PART C: Adding functionality to the menu item.

The new menu item can have functionality in four ways:

predefined functionality by SAP programmer

transaction code

program exit

area menu'

7. You do not have control over the first method of functionality to a menu exit. In some cases, SAP programmers will have predefined code that is executed once you activate the menu exit.

8. If the menu exit function code is a type u201CTu201D function code, you will need to create a transaction code to add functionality to the new menu item. (To find the type of the function code, just double click on the function code in the GUI screen) The transaction code should have the same name as the function code (remember: it will start with a plus sign). The transaction code you create can either call an online (module pool) program or a report. You can create a transaction code from the object browser.

9. If the functionality for a menu exit is to be placed in a program exit, the menu exit and corresponding program exit will belong to the same enhancement.

Examining the enhancement that contains the menu exit can give you an initial indication that a program exit is needed to add functionality. You can code the program exit by double clicking on the component in your project or examining the SAP code to find the corresponding check of the function code triggered. For the appropriate function code, you will see a u201CCALL CUSTOMER-FUNCTIONu201D statement.

10. The last way of adding functionality is through area menuu2019s. An area menu is a transaction that serves as a collection point for several other transactions. Unlike other dialog transactions, area menus do not have underlying programs, hence, you cannot append your own functions to them.

No screens accompany an area menu. An area menu has only one title and status, both of which are assigned by the system. Area menus allow you to create menus containing functions that are customized for a particular function in your company. Creating an area menu is similar to creating a standard menu. However, instead of specifying functions for menu options you specify transaction codes.

To navigate to area menuu2019s choose Development -> Other tools -> Area menus. The name of the area menu should be same as that of the function code of the menu exit.

Step by step procedure for creating Screen Exits

PART A: Search for the screen exit.

1. A screen exit is a way to add a sub-screen and corresponding functionality to an SAP transaction. The first step is to navigate to the screen where you want to attach menu exit.

2. Go to the field list of that screen through system -> status or F1 -> Technical details and look for fields that have subscreen as the field type for that particular screen. These are the area's on the main screen which can be enhanced.

PART B: Creating your own subscreen.

3. Identify the enhancement and its component that has the provision for creating the screen exit for that particular screen.

Note A: To know more about how to identify the enhancement, refer to the document on Locating User Exits.

Note B: All SAP provided subscreenu2019s may not have the scope for enhancement. There are a limited number of transactions which has scope for screen exit. Refer to Annexure A for details.

4. Include the Enhancement in your own project through transaction CMOD.

5. Go to Enhancement Components and double click on the component name.

6. It will take you to the screen attributes for that particular subscreen.

u2022 The screen type should be subscreen.

u2022 Maintain the size of the subscreen through Lines/Columns attribute. This should correspond to the size of the subscreen mentioned in the main SAP screen.

u2022 The development class for the subscreen should be the development class for the project.

7. Create the subscreen using the fullscreen editor.

8. You can add your own modules in the subscreenu2019s flow logic. However, one has to be careful regarding data transfer between the main screen and the subscreen. For more details refer to R/3 On-line Help.

9. Generate the screen.

PART C: Activating the project

10. Use the back button to navigate back to the project enhancement main screen.

11. Activate the project.

Locating User Exits

Before you can add functionality to a SAP system, you need to be able to locate the appropriate user exits. SAP has provided around 2000 user exits.

Searching from transaction CMOD

Searching from the Application Hierarchy

Making your own customized search

Keep in mind that you must first search for an enhancement. Once you find an enhancement, you can display its components -- the actual user exits. Then you need to include the enhancement containing the required user exit as a component in your own project.

Method #1: Using Transaction CMOD

u2022 Transaction CMOD contains search functionality to help locate enhancements.

u2022 Selecting the "Utilities -> SAP enhancements" menu path in transaction CMOD will take you to an enhancement selection screen .

u2022 You can limit the search for enhancements based on:

Enhancement name

Development class

u2022 After clicking on the u2018Executeu2019 pushbutton (or u2018F8u2019) on the selection screen, the system will display a listing of the development classes that contain enhancements (see graphic above).

u2022 From this listing, you can double-click a development class to display its enhancements.

u2022 If you have clicked on the u2018Display componentsu2019 pushbutton on the selection screen (see graphic on previous page), the components of each enhancement will automatically be displayed.

Remark: To use this search method one must either know the part of the enhancement name or the development class. But if one looks at SAPu2019s naming convention for user exits (see note below), the screen numbers/program names/ function codes/etc are contained in the components name and there is no scope for that in selection options. Also one cannot restrict the search to only one type of exit.

Method #2: Using SAP Application Hierarchy

u2022 Selecting the "Overview -> Applic. hierarchy -> SAP" menu path in the ABAP/4 Development Workbench will take you to a listing of all standard SAP applications and components .

u2022 To locate a user exit for a particular application, follow these steps

from the SAP Application Hierarchy:

u2022 Select the appropriate application by single clicking on it.

u2022 Choose the "Edit Sel./desel. subtree" menu path.

u2022 Click on the u2018Repository Infosys.u2019 pushbutton.

u2022 This will take you to the ABAP/4 Repository Information System.

u2022 Double click on the u2018Environmentu2019 branch.

u2022 Double click on the u2018Customer enhancementu2019 branch.

u2022 Double-click on the u2018Customer exitu2019 branch.

u2022 This will take you to the customer exit (or enhancement) selection screen with the appropriate development class for the application selecting on the Application Hierarchy.

u2022 Click on the u2018Executeu2019 pushbutton.

u2022 This will take you to a listing of all enhancements that meet the selection criteria.

From this listing, you can display the components of each enhancement and the documentation. You will be taken automatically to transaction SMOD from the ABAP/4 Repository Information System.

Remark: To use this one must have knowledge about the application hierarchy to which that particular enhancement belongs. Also one has to explode individual enhancements to identify weather the component is contained in that enhancement.

Like previous method, there is no scope for selection option on the components name.

Method #3: Writing a small report program

The details about projects, enhancements and components are contained in two SAP tables:

MODSAP: containing enhancement name, type of exit and component

MODACT: containing project name and enhancements

Thus by writing a report program to retrieve data from these two tables, you can customize your search requirements. Code for one such sample program is attached in annexure A and the corresponding transaction code to execute this program is YSMD .

Using this you can list all components that match a particular string like the program name or the function code as well as search for only one type of exit.

NOTE: SAPu2019s naming convention for user exits-

u2022 Program/Function exits : EXIT_AAAAAAAA_nnn where

AAAAAAAA stands for the program name which contains the exit and

nnn is a SAP assigned number starting from 001

u2022 Menu exits : AAAAAAAA+XXX where

AAAAAAAA stands for the program name which contains the exit and

+XXX is the name of the function code contained in the menu item

u2022 Screen Exits : AAAAAAAA_nnnn_BBBBBBBB_CCCCCCCC_mmmm where

AAAAAAAA : calling program name

nnnn : calling screen number

BBBBBBBB : area

CCCCCCCC : called program name

mmmm : called screen number

there is another way to find the user-exit functions with using se30 transaction .

Write MM01 in Transaction checkbox and push the execute button.

Then create a material and save it.

last of all, push the evaluate button in se30.

push the hit list button to see hit list .

search 'EXIT_' in hit list. you can see the user-exist fucntions.

This may help .

[Former Member]

that way I find some points having exit_ but how do find out which one is a user exit at the "savebutton"?

[Former Member]

Hi,

i use se30 to find user-exits.

these are the steps what i did.

1 - run mm01 with using se30

2 - i create a material with just filling the required fields for only 'basic data' view

3 - then i search EXIT_SAP in hit list.

4 - i get these results :

Call Func. EXIT_SAPLOMCV_902

Call Func. EXIT_SAPLMGMU_001

Call Func. EXIT_SAPLOMCV_901

Call Func. EXIT_SAPLMG02_001

5 - These are the 'probably' user-exits for save button.

this is just a way, a strong way but not exact way.

[Former Member]

Most user exits can be found in SPRO. E.g. the ones for the material master are under: Logistics General --> Material Master --> Enhancement. Advantage of this is that you find User exits and BAdI's and they come with documentation.

[Former Member]

i found the exit it is MGA00001 . But this one is used in another project already (must have added somebody else). Is it correct that I can use an enhancement in max one enhancement project?

So if it is already I do have a problem, correct?

[Former Member]

Hi Daniel,

The Exit what you have mentioned is corret.

MGA00001

You are saying that it is used by other one. So When u create a project in CMOD then give short description and then you save the data and click on Enhancement Assignments. There you will get that and u can use it.

If it is used by any other project it shows a status message saying that it is already used by this project.

So you should deactivate that project and create another project by using that exit.

You can write your code in the function module exit.

i.e., EXIT_SAPLMGMU_001. By double clicking on that you will be getting an include. So inorder to check whether that particular exit is trigerring or not you keep break point in that include and then u create material in mm01. Whwn u click on save then it gets triggers.

When you keeep break point it is better to keep break username because it only triggers for you only.

Reward points if useful.

Thanks,
