Menu-exits, Function-exits & Screen-exits

What is Menu-exits, Function-exits & Screen-exits ? explain

Hi,
      Why do you need enhancements ?
The standard applications do not offer some of the functionality you need. The R/3 enchancement concept allows you to add your own functionality to SAP's standard business applications.
What are the different types of enhancements ?
Enhancements using customer exits
Customers' potential requirements which are not included in the standard software are incorporated in the standard as empty modification 'shells'. Customers can then fill these with their own coding. Enhancements can relate to programs, menus and screens. Upward compatibility is assured. In other words, SAP guarantees that the jump from the standard software to the exit and the interface which call the exit will remain valid in future releases.
Enhancements to ABAP/4 Dictionary elements
These are ABAP/4 Dictionary enhancements (creation of table appends), text enhancements (customer-specific key words and documentation for data elements) and field exits (creation of additional coding for data elements).
What is customer development ?
Creating customer-specific objects within the customer name range.
What is SSCR ?
SSCR (SAP Software Change Registration) is a procedure, for registering all manual changes to SAP source coding and SAP Dictionary objects.
What is the difference between modifications and enhancements ?
Modifications mean making changes to the SAP standard functionality.
Enhancements mean adding some functionality to SAP standard functionality.
What are the disadvantages of modification ?
Modifying standard code can lead to errors
Modifications mean more work during software upgrades
What are the advantages of enhancements ?
Do not affect standard SAP source code
Do not affect software upgrades
when do you opt for modification ?
Customer exits are not available for all programs and screens within the R/3 standard applications. You can only use exits if they already exist within the SAP R/3 System . Otherwise you have to opt for modifications .
What are the various types of customer exits ?
Menu exits
Screen exits
Function module exits
Keyword exits
What is a menu exit ?
Adding items to the pulldown menus in standard R/3 applications .
13.What is a screen exit ?
Adding fields to the screens within R/3 applications. SAP creates screen exits by placing special subscreen areas within a standard R/3 screen and calling a customer subscreen from within the standard dynpro's flow logic.
What is a function module exit ?
Adding functionality to R/3 applications. Function module exits play a role in both menu and screen exits.
What is a keyword exit ?
Add documentation to the data elements of key words defined in the ABAP/4 Dictionary. The system displays this documentation whenever a user presses F1 to get online help for a screen field.
How do SAP organizes its exits ?
SAP organizes its exits in packages that are called SAP enhancements. Each SAP enhancement can contain many individual exits

  • Menu Exits and Screen Exits

    hi everyone,
    can you send me some examples on menu exits and screen exits.
    thank you.
    preetham

    Hi Preetham,
    In older versions MENU Exits approached through Transaction CMOD by creating
    PROJECTS and activating the project and assigning Program to that
    Transaction Codes. For MENU Exits, Transaction Codes will be starting with
    "+" sign and with default text "NODE TEXT NOT FOUND" for which you can
    assign your Report or Dialog Program etc., (for Eg:- +DW4 MENU Exits
    Transaction available in TOOLS --> ABAP Workbench --> Utilities --> <Node
    Text Not found>).
    Procedure for Creating MENU Exits.
    1) To get into Area Menu Maintenance Screen Type SE43 T.Code in Command
    Line.
    2) In Area Menu Paramenter type 'S000' (S triple Zero)
    3) Then Press Change Icon in Application Tool Bar. Then It may ask for
    Access Key [or] it may display "Specify Processing mode" window. If it ask
    for the Access Key Check for the availability of OSS Note and apply to open
    Standard SAP Menu to include MENU Exits. Otherwise, if it display "Specify
    Processing mode" window with Three Push Button. In which select "Change" and
    proceed further.
    4) Then it will display "Information" window with the following information
    "Caution : The Original Language of the structure is German (editing lang. :
    English) ". Then press "Enter Key to proceed further.
    5) Then you will get into "Edit Area Menu S000".
    6) for eg:- Expand Tools Menu.
    7) Then Press ABAP Workbench <Icon>.
    8) Then you will get into ABAP Workbench Menu Tree.
    9) Then Expand Utilities Menu.
    10) In the last line you will find one MENU EXIT Provision to include your
    own menu. "Node Text Not Found" This text can be change by double Clicking
    that. There you can find the T.Code. Here for Eg:- "+DW4".
    11) for eg: - Here change the Text to "Sample Menu Exit" and then note down
    the T.Code "+DW4".
    12) Then Save with Change Request Number and come out of Transaction SE43.
    13) Then Goto Transaction SE93.
    14) Then type T.Code "+DW4" and press Create.
    15) Then proceed further to create transaction called "+DW4".
    I hope this could help you in Creating Menu Exit...

    Menu exits allow you to add your own functions to the pulldown menus in standard R/3 transactions. To take advantage of a menu exit, you first need to create a project as described in the section Creating an add-on project. Then, you must include the SAP enhancement package that contains the menu exit you want to use in your project. From the main screen of the Project management transaction, proceed as follows:
    Select Enhancement components and choose Change.
    The system lists all customer exits contained in the enhancements included in your project.
    Place the cursor on the menu exit you want to add your own function to.
    Choose Edit component.
    The system displays technical information about the menu entry. It also displays two input fields where you can specify a language and the text you want your menu item to have.
    Enter the name of your menu function (such as Special order method) in the field New text.
    Choose Save text.
    Your special menu function will not appear in the pulldown menu of the corresponding standard transaction until you activate your enhancement project.
    Specifying a menu text and activating your project are not the only steps you need to take to make your own menu item work. After you carry out these steps, your menu item will appear, but it will not call a corresponding function. To attach your menu entry to its corresponding function, you need to create a function module for the function module exit associated with your menu text. This function module exit is part of the same SAP enhancement that contains the menu exit you used. Creating Customer-Specific Function Modules tells you more about how to use function module exits.

    How to implement screen exit for a SAP standard transaction
    Introduction
    SAP provides standard transactions to enter data into database. But a client may want to maintain some additional information in SAP other than what is provided.
    To make provisions for this, additional screens have to be provided and additional fields must be added into appropriate database table.
    To pave way for this, SAP has provided the option for screen exits. Usually, SAP provides the following:
    An append structure in the database table with the new fields.
    A subscreen area into the standard screen – where the programmer can attach his subscreen of his own program with the new fields.
    A function group under which the new subscreen has to be created with the new fields.
    Function exits to synchronize the PBO and PAI of the standard SAP program with the PBO and PAI of the subscreen – so that data can flow back and forth between the standard SAP program and the program written by the developer for the subscreen. These function modules also exist in the same function group under which the subscreen will have to be developed.
    Finally, a linkage has to be done between the subscreen area of standard SAP screen with the custom subscreen constructed by the developer.
    Typically, SAP provides an enhancement in which the developer can create an append structure, use the function exits to synchronize the PBO and PAI of the standard SAP program and the custom subscreen program, and make the necessary linking( as mentioned above in step 4. But, again, this is not a hard and fast rule. Linking in some case, is also done by configurations.) SAP also usually provides the name of the function group under which the subscreen has to be developed.
    Necessary guidance about implementing a screen exit development is usually available in the Documentation section of the enhancement ( can be availed by transaction SMOD).
    Pre-Requisites
    The developer to work on screen exit should have essential knowledge on the following:
    DDIC concepts, including the knowledge of append structure.
    Concept of SAP Enhancements and implementing them using Projects.
    Concept of function exits.
    Knowledge on Module Pool – including subscreens, Tabstrip controls etc.
    Steps
    Guidelines
    So, a developer can follow the guidelines mentioned below to implement a screen exit to a standard SAP transaction, as and when required:
    Find out the Required Enhancements
    Go to SMOD. Press F4 in the Enhancement field. In the next popup window, click pushbutton ‘SAP Applications’. A list will appear that contains information on all the enhancements, categorized under functional areas. Developer must search for the enhancements relevant to his functional area of interest – for e.g., Purchasing, Asset Accounting, etc.
    Note down the enhancements. Then, come to the initial screen of SMOD and view the documentation of each enhancement to find out which one is required for your development.
    Utilize the Enhancement in a Project
    After you have found one, do as directed in the documentation. Generally, the steps are as follows:
    Create a project using CMOD including your enhancement.
    Create the append structure with new fields.
    Go to the desired function group and create a subscreen with the new fields. Write PBO and PAI for the subscreen, if required.
    Use the function exits in the enhancement to link the PBO and PAI of the subscreen with that of the main SAP program supporting the SAP transaction.
    Maintain necessary linkage between the subscreen area of standard SAP program with the custom subscreen developed along with the custom program name. This can be done in the project (developed by CMOD including the enhancement) or outside as a part of configuration.
    Activate the project.
    Test to ensure that required functionality are met.
    Case Study 1
    Add three new custom fields for Asset master and maintain information for them
    Requirement
    Three fields in the legacy system have to be maintained in Asset master. These fields are:
    Original Asset number – 20 characters
    Location 2 – 15 Characters.
    Model no – 20 characters
    Location 2 should start with ‘L’.
    Pre-Analysis
    Finding out the Enhancement
    As described above, the enhancement is determined. It was found, that enhancement AIST0002 will serve the purpose. It contains the following components (can be viewed by transaction SMOD):
    Exit Type Description EXIT_SAPL1022_001 Function Exit Check of User-Defined Fields when Using Create and Change BAPI EXIT_SAPLAIST_002 Function Exit Transfer Data for User Subscreens in PBO. EXIT_SAPLAIST_003 Function Exit Transfer of User-Defined Fields to SAP Master Data Transactions CI_ANLU Customizing Include Include structure to add new fields
    Studying the Function Exits
    The function module level documentation for the function exits are then viewed from transaction SE37. The documentation clearly laid out for the purpose for their use:
    EXIT_SAPLAIST_002
    Function module Level Documentation
    This function module is called by asset master data maintenance at the start of the dialog. (When changing, it is called after reading of the data from the database; when creating it is called after the transfer of the default values from the asset class and reference asset.) The purpose of the function module is to enable this function group to recognize the master data. For interpreting or controlling master data fields that are important for user fields, it is possible to transfer to global variables at this point, so that they can be recognized when the user subscreens are processed.
    Import Parameters
    Understanding
    This function module is called at the PBO to pass the information retrieved from the database to pass them to the custom subscreen and its underlying program. Import parameter : I_ANLU will be populated with the values for user-defined fields which will be passed to the subscreen program. So, there must be some sort of variable assignment from I_ANLU.
    EXIT_SAPLAIST_003
    Function module Documentation: This function module is called by SAP asset master data maintenance after the screens are processed, but before saving. The purpose of the function module is to transfer fields entered on user sub-screens of SAP asset data maintenance to the database for updating. The export parameter for this function module is:
    Understanding
    This function module will be used to transfer the user entered data in the subscreen fields to the main SAP program, which will then be saved into the database.
    Studying the Documentation of the Enhancement
    The enhancement documentation (as is viewed from the initial screen of SMOD] also supports the idea. Moreover, it informs that we need to develop a subscreen under function group XAIS. This is the function group under which the two function exit modules also exist. So, if the custom subscreen refers to the global data of the function group XAIS, then those values will also be available to these function exits as well.
    Going to SE80 and viewing the function group XAIS helps us to inform that there are three DDIC tables declared for it:
    Deciding the Final course of Action
    After making all the investigations, the final course of action was determined.
    SrlNo Step Justification
    A project has to be created using transaction CMOD where the enhancement AIST0002 will be included.
    Customizing include CI_ANLU has to be created with the custom fields demanded When CI_ANLU will be developed, the custom fields will get appended to the database table ANLU. Also, these fields will be used to create screen fields in the new subscreen.
    A custom subscreen, say, 9000 will be developed under function group XAIS. The screen group for the screen will be ‘CUST’ (or any name). The three custom fields added to table ANLU (by creating CI_ANLU) will be used to create new fields in the screen.
    In the PAI of the subscreen, validation for Location to start with ‘L’ will be added. The subscreen with three new fields has to be developed so that it can be attached to a subscreen area of the asset master screens.
    In the custom include of the function exit module ‘EXIT_SAPLAIST_002’, the following code will be written:-
    ANLU = I_ANLU. I_ANLU is the import parameter of this FM. The value is assigned to the global variable ANLU, referring which the three new subscreen fields are developed. So, data retrieved from database table ANLU will be passed to this FM as I_ANLU by the standard SAP main program. The value will be taken and passed to the global variable of the function group XAIS, so that the three custom fields (referring to ANLU of XAIS) get populated.
    In the custom include of the function exit module ‘EXIT_SAPLAIST_003’, the following code will be written:-
    E_ANLU = ANLU. The changed values in the subscreen fields exist in global variable ANLU for the function group XAIS. This function exit module will pass the data back to the SAP main program as E_ANLU.
    Proper linkage/configuration has to be done so that the new subscreens get linked to the appropriate subscreen area of the Asset master screen. This has to be done – otherwise, the new custom subscreen will not be displayed in the Asset master screens.
    Development
    Creating a Project to include the enhancement
    Go to transaction CMOD and create a project.
    Enter a description for the project. Then, click on the pushbutton ‘Enhancement Assignments’ in the Application Toolbar.
    Enter the name of the enhancement and Save.
    Go to ‘Components’.
    Creating Custom Include for ANLU
    The screen shown below will appear, showing all the enhancement components under the assignment AIST0002. Double-click on the name of the Include Structure to create it.
    Create the include structure with three new fields, as required. Then, save and activate it.
    Develop the subscreen and the program
    Go to transaction SE80. For the function group XAIS, create a new subscreen 9000.
    Create it as subscreen.
    Then, go to the Layout of the screen and create three new fields from Database table ANLU.
    Drag the fields in the screen body and place them.
    Then, save and activate the screen and come back to screen flow editor.
    Create the PAI module to add validation for field “Location 2”, as required .
    Activate the whole function group and come out.
    Write code in the Function Exits to synchronize the programs
    Now, code has to be written in the function modules EXIT_SAPLAIST_002 and EXIT_SAPLAIST_003 so that data flows to and fro between the main SAP program and custom subscreen program. For that, go back to transaction CMOD and change the function exits.
    Write code in the function module EXIT_SAPLAIST_002 called once at the beginning of the transaction:
    Write code in EXIT_SAPLAIST_003 to pass the data from the subscreen to SAP main program.
    Then, activate everything – the whole project and come out.
    Complete the configuration to link the subscreen
    The development portion is complete. Now, linking of the subscreen has to be done with the subscreen area of the main program. In most of the cases, this linking can be done in the enhancement itself. But, here, requirement is a bit different. It is done by configuration using SPRO.
    Assets are created under Asset class. And for each asset class, there is a layout assigned to it. For a layout, there are multiple tab pages assigned to it. And, for each tab page, there are multiple screen groups/field groups assigned.
    Here, the requirement is to create these three custom fields in the tab page ‘General’ of asset master screen ( AS01/AS02/AS03/AS91).
    Determine the Layout
    To achieve this, first of all, we need to find out which layout is assigned to asset class 1000.For that, go to transaction AOLK( information has to be obtained from functional consultant).Select the Asset Class ‘1000’ and click on folder ‘General Assignment of Layout’.
    Here, for Asset class 1000, for all the user groups, tab layout SAP is assigned. Since layout ‘SAP’ cannot be changed, it has to be copied and manipulated to include our screen group. Later, the new layout has to be assigned over here.
    Create new tab layout
    Go to transaction AOLA. Copy the tab layout ‘SAP’ to create another layout, say, YSUB.
    System will copy all the settings and will inform you about that.
    Select your newly created layout and double-click on the folder ‘Tab page titles’.
    You want to put your custom fields in the tab page “General”. So, select this tab page entry and double-click on the folder "Position of Groups".
    Here, all the field groups currently residing in the tab-page “General” are shown. Add an entry for your newly created fields.
    Select the group box from the list. An entry will come with “U” padded with the custom subscreen prepared by you.
    Then, save and come out.
    Assign the new Layout to Asset Class
    Now, go to tcode AOLK and assign tab layout YSUB for asset class 1000.
    Save and come out.
    Test the Exit
    Everything is over. Now, go to transaction code AS01/02/03 or AS91 to deal with an asset of asset class 1000. You will see your new fields added to the screen. Add values to them…save. Then, enter into the tcodes again to see whether the values entered by you are being displayed or not.

    Menu exits allow you to add your own functions to the pulldown menus in standard R/3 transactions. To take advantage of a menu exit, you first need to create a project as described in the section Creating an add-on project. Then, you must include the SAP enhancement package that contains the menu exit you want to use in your project. From the main screen of the Project management transaction, proceed as follows:
    Select Enhancement components and choose Change.
    The system lists all customer exits contained in the enhancements included in your project.
    Place the cursor on the menu exit you want to add your own function to.
    Choose Edit component.
    The system displays technical information about the menu entry. It also displays two input fields where you can specify a language and the text you want your menu item to have.
    Enter the name of your menu function (such as Special order method) in the field New text.
    Choose Save text.
    Your special menu function will not appear in the pulldown menu of the corresponding standard transaction until you activate your enhancement project.
    Specifying a menu text and activating your project are not the only steps you need to take to make your own menu item work. After you carry out these steps, your menu item will appear, but it will not call a corresponding function. To attach your menu entry to its corresponding function, you need to create a function module for the function module exit associated with your menu text. This function module exit is part of the same SAP enhancement that contains the menu exit you used. Creating Customer-Specific Function Modules tells you more about how to use function module exits.
    User exits (Function module 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 functionmodule exits is:
    EXIT_<program name><3 digit suffix>
    The call to a functionmodule exit is implemented as:
    CALL CUSTOMER.-FUNCTION <3 digit suffix>
    To find a Exit.
    Goto Transaction -- Find The Package
    SMOD >f4>Use the Package here to Find the Exits In the Package.
    Else if you Want to search by Application Area wise ,

  • Screen exit and menu exit

    want some examples and step by step guide for menu exits and 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.
    the tcode is cmod...
    1.From the main screen of the Project management transaction, proceed as follows:
    Select Enhancement components and choose Change.
    2.Choose Edit component.
    3.Choose the screen exit and double click on it
    4.Create your subscreen using the Screen Painter.
    5.Design your screen to be added to the standard screen and activate the particular screen and return back to the flow logic .
    6.Choose the PAI and PBO to write down the logic.
    7.Generate your screen and choose Back (the green arrow) to return to the Project management transaction.
    8.Go to the transaction ME22 to view the customer defined screen exit.
    9.Enter the purchase order number and press Enter.
    10.Go to the menu header --> Details.
    11.Purchase number is visible on the standard screen
    check the foll link,
    http://wiki.ittoolbox.com/index.php/HOWTO:Implement_a_screen_exit_to_a_standard_SAP_transaction
    Menu exits allow you to add your own functions to the pulldown menus in standard R/3 transactions. To take advantage of a menu exit, you first need to create a project as described in the section Creating an add-on project. Then, you must include the SAP enhancement package that contains the menu exit you want to use in your project. From the main screen of the Project management transaction, proceed as follows:
    Select Enhancement components and choose Change.
    The system lists all customer exits contained in the enhancements included in your project.
    Place the cursor on the menu exit you want to add your own function to.
    Choose Edit component.
    The system displays technical information about the menu entry. It also displays two input fields where you can specify a language and the text you want your menu item to have.
    Enter the name of your menu function (such as Special order method) in the field New text.
    Choose Save text.
    Your special menu function will not appear in the pulldown menu of the corresponding standard transaction until you activate your enhancement project.
    Specifying a menu text and activating your project are not the only steps you need to take to make your own menu item work. After you carry out these steps, your menu item will appear, but it will not call a corresponding function. To attach your menu entry to its corresponding function, you need to create a function module for the function module exit associated with your menu text. This function module exit is part of the same SAP enhancement that contains the menu exit you used. Creating Customer-Specific Function Modules tells you more about how to use function module exits.

    How to implement screen exit for a SAP standard transaction
    Introduction
    SAP provides standard transactions to enter data into database. But a client may want to maintain some additional information in SAP other than what is provided.
    To make provisions for this, additional screens have to be provided and additional fields must be added into appropriate database table.
    To pave way for this, SAP has provided the option for screen exits. Usually, SAP provides the following:
    An append structure in the database table with the new fields.
    A subscreen area into the standard screen – where the programmer can attach his subscreen of his own program with the new fields.
    A function group under which the new subscreen has to be created with the new fields.
    Function exits to synchronize the PBO and PAI of the standard SAP program with the PBO and PAI of the subscreen – so that data can flow back and forth between the standard SAP program and the program written by the developer for the subscreen. These function modules also exist in the same function group under which the subscreen will have to be developed.
    Finally, a linkage has to be done between the subscreen area of standard SAP screen with the custom subscreen constructed by the developer.
    Typically, SAP provides an enhancement in which the developer can create an append structure, use the function exits to synchronize the PBO and PAI of the standard SAP program and the custom subscreen program, and make the necessary linking( as mentioned above in step 4. But, again, this is not a hard and fast rule. Linking in some case, is also done by configurations.) SAP also usually provides the name of the function group under which the subscreen has to be developed.
    Necessary guidance about implementing a screen exit development is usually available in the Documentation section of the enhancement ( can be availed by transaction SMOD).
    Pre-Requisites
    The developer to work on screen exit should have essential knowledge on the following:
    DDIC concepts, including the knowledge of append structure.
    Concept of SAP Enhancements and implementing them using Projects.
    Concept of function exits.
    Knowledge on Module Pool – including subscreens, Tabstrip controls etc.
    Steps
    Guidelines
    So, a developer can follow the guidelines mentioned below to implement a screen exit to a standard SAP transaction, as and when required:
    Find out the Required Enhancements
    Go to SMOD. Press F4 in the Enhancement field. In the next popup window, click pushbutton ‘SAP Applications’. A list will appear that contains information on all the enhancements, categorized under functional areas. Developer must search for the enhancements relevant to his functional area of interest – for e.g., Purchasing, Asset Accounting, etc.
    Note down the enhancements. Then, come to the initial screen of SMOD and view the documentation of each enhancement to find out which one is required for your development.
    Utilize the Enhancement in a Project
    After you have found one, do as directed in the documentation. Generally, the steps are as follows:
    Create a project using CMOD including your enhancement.
    Create the append structure with new fields.
    Go to the desired function group and create a subscreen with the new fields. Write PBO and PAI for the subscreen, if required.
    Use the function exits in the enhancement to link the PBO and PAI of the subscreen with that of the main SAP program supporting the SAP transaction.
    Maintain necessary linkage between the subscreen area of standard SAP program with the custom subscreen developed along with the custom program name. This can be done in the project (developed by CMOD including the enhancement) or outside as a part of configuration.
    Activate the project.
    Test to ensure that required functionality are met.
    Case Study 1
    Add three new custom fields for Asset master and maintain information for them
    Requirement
    Three fields in the legacy system have to be maintained in Asset master. These fields are:
    Original Asset number – 20 characters
    Location 2 – 15 Characters.
    Model no – 20 characters
    Location 2 should start with ‘L’.
    Pre-Analysis
    Finding out the Enhancement
    As described above, the enhancement is determined. It was found, that enhancement AIST0002 will serve the purpose. It contains the following components (can be viewed by transaction SMOD):
    Exit Type Description EXIT_SAPL1022_001 Function Exit Check of User-Defined Fields when Using Create and Change BAPI EXIT_SAPLAIST_002 Function Exit Transfer Data for User Subscreens in PBO. EXIT_SAPLAIST_003 Function Exit Transfer of User-Defined Fields to SAP Master Data Transactions CI_ANLU Customizing Include Include structure to add new fields
    Studying the Function Exits
    The function module level documentation for the function exits are then viewed from transaction SE37. The documentation clearly laid out for the purpose for their use:
    EXIT_SAPLAIST_002
    Function module Level Documentation
    This function module is called by asset master data maintenance at the start of the dialog. (When changing, it is called after reading of the data from the database; when creating it is called after the transfer of the default values from the asset class and reference asset.) The purpose of the function module is to enable this function group to recognize the master data. For interpreting or controlling master data fields that are important for user fields, it is possible to transfer to global variables at this point, so that they can be recognized when the user subscreens are processed.
    Import Parameters
    Understanding
    This function module is called at the PBO to pass the information retrieved from the database to pass them to the custom subscreen and its underlying program. Import parameter : I_ANLU will be populated with the values for user-defined fields which will be passed to the subscreen program. So, there must be some sort of variable assignment from I_ANLU.
    EXIT_SAPLAIST_003
    Function module Documentation: This function module is called by SAP asset master data maintenance after the screens are processed, but before saving. The purpose of the function module is to transfer fields entered on user sub-screens of SAP asset data maintenance to the database for updating. The export parameter for this function module is:
    Understanding
    This function module will be used to transfer the user entered data in the subscreen fields to the main SAP program, which will then be saved into the database.
    Studying the Documentation of the Enhancement
    The enhancement documentation (as is viewed from the initial screen of SMOD] also supports the idea. Moreover, it informs that we need to develop a subscreen under function group XAIS. This is the function group under which the two function exit modules also exist. So, if the custom subscreen refers to the global data of the function group XAIS, then those values will also be available to these function exits as well.
    Going to SE80 and viewing the function group XAIS helps us to inform that there are three DDIC tables declared for it:
    Deciding the Final course of Action
    After making all the investigations, the final course of action was determined.
    SrlNo Step Justification
    A project has to be created using transaction CMOD where the enhancement AIST0002 will be included.
    Customizing include CI_ANLU has to be created with the custom fields demanded When CI_ANLU will be developed, the custom fields will get appended to the database table ANLU. Also, these fields will be used to create screen fields in the new subscreen.
    A custom subscreen, say, 9000 will be developed under function group XAIS. The screen group for the screen will be ‘CUST’ (or any name). The three custom fields added to table ANLU (by creating CI_ANLU) will be used to create new fields in the screen.
    In the PAI of the subscreen, validation for Location to start with ‘L’ will be added. The subscreen with three new fields has to be developed so that it can be attached to a subscreen area of the asset master screens.
    In the custom include of the function exit module ‘EXIT_SAPLAIST_002’, the following code will be written:-
    ANLU = I_ANLU. I_ANLU is the import parameter of this FM. The value is assigned to the global variable ANLU, referring which the three new subscreen fields are developed. So, data retrieved from database table ANLU will be passed to this FM as I_ANLU by the standard SAP main program. The value will be taken and passed to the global variable of the function group XAIS, so that the three custom fields (referring to ANLU of XAIS) get populated.
    In the custom include of the function exit module ‘EXIT_SAPLAIST_003’, the following code will be written:-
    E_ANLU = ANLU. The changed values in the subscreen fields exist in global variable ANLU for the function group XAIS. This function exit module will pass the data back to the SAP main program as E_ANLU.
    Proper linkage/configuration has to be done so that the new subscreens get linked to the appropriate subscreen area of the Asset master screen. This has to be done – otherwise, the new custom subscreen will not be displayed in the Asset master screens.
    Development
    Creating a Project to include the enhancement
    Go to transaction CMOD and create a project.
    Enter a description for the project. Then, click on the pushbutton ‘Enhancement Assignments’ in the Application Toolbar.
    Enter the name of the enhancement and Save.
    Go to ‘Components’.
    Creating Custom Include for ANLU
    The screen shown below will appear, showing all the enhancement components under the assignment AIST0002. Double-click on the name of the Include Structure to create it.
    Create the include structure with three new fields, as required. Then, save and activate it.
    Develop the subscreen and the program
    Go to transaction SE80. For the function group XAIS, create a new subscreen 9000.
    Create it as subscreen.
    Then, go to the Layout of the screen and create three new fields from Database table ANLU.
    Drag the fields in the screen body and place them.
    Then, save and activate the screen and come back to screen flow editor.
    Create the PAI module to add validation for field “Location 2”, as required .
    Activate the whole function group and come out.
    Write code in the Function Exits to synchronize the programs
    Now, code has to be written in the function modules EXIT_SAPLAIST_002 and EXIT_SAPLAIST_003 so that data flows to and fro between the main SAP program and custom subscreen program. For that, go back to transaction CMOD and change the function exits.
    Write code in the function module EXIT_SAPLAIST_002 called once at the beginning of the transaction:
    Write code in EXIT_SAPLAIST_003 to pass the data from the subscreen to SAP main program.
    Then, activate everything – the whole project and come out.
    Complete the configuration to link the subscreen
    The development portion is complete. Now, linking of the subscreen has to be done with the subscreen area of the main program. In most of the cases, this linking can be done in the enhancement itself. But, here, requirement is a bit different. It is done by configuration using SPRO.
    Assets are created under Asset class. And for each asset class, there is a layout assigned to it. For a layout, there are multiple tab pages assigned to it. And, for each tab page, there are multiple screen groups/field groups assigned.
    Here, the requirement is to create these three custom fields in the tab page ‘General’ of asset master screen ( AS01/AS02/AS03/AS91).
    Determine the Layout
    To achieve this, first of all, we need to find out which layout is assigned to asset class 1000.For that, go to transaction AOLK( information has to be obtained from functional consultant).Select the Asset Class ‘1000’ and click on folder ‘General Assignment of Layout’.
    Here, for Asset class 1000, for all the user groups, tab layout SAP is assigned. Since layout ‘SAP’ cannot be changed, it has to be copied and manipulated to include our screen group. Later, the new layout has to be assigned over here.
    Create new tab layout
    Go to transaction AOLA. Copy the tab layout ‘SAP’ to create another layout, say, YSUB.
    System will copy all the settings and will inform you about that.
    Select your newly created layout and double-click on the folder ‘Tab page titles’.
    You want to put your custom fields in the tab page “General”. So, select this tab page entry and double-click on the folder "Position of Groups".
    Here, all the field groups currently residing in the tab-page “General” are shown. Add an entry for your newly created fields.
    Select the group box from the list. An entry will come with “U” padded with the custom subscreen prepared by you.
    Then, save and come out.
    Assign the new Layout to Asset Class
    Now, go to tcode AOLK and assign tab layout YSUB for asset class 1000.
    Save and come out.
    Test the Exit
    Everything is over. Now, go to transaction code AS01/02/03 or AS91 to deal with an asset of asset class 1000. You will see your new fields added to the screen. Add values to them…save. Then, enter into the tcodes again to see whether the values entered by you are being displayed or not.

  • Menu Exit and Screen Exit

    Hi PPL,
    Can anybody help me out in explaining me how to find a menu exit or the
    Screen exit in a program...I have an requirement where i need to use both of them..
    I have already posted this query , but people responded with links which had the
    information on these two , but not the way to locate these...
    I ll be very grateful for ur advice.
    Regards,
    Kevin Nick.

    hi kevin
    <b>Screen exits</b> are exits that allow you to use a reserved part of the screen (A subscreen) to display or input data.
    It is determined be SAP where the sub screen will be displayed.
    The syntax is: CALL CUSTOMER-SUBSCREEN
    The screen exit is not processed untill the corresponding subscreen has been created in an enhancement project, and the project has been activated.
    Note:
    Function codes are only processed in the main screens flow logic
    You are not allowed to enter a name for the subscreens command field
    You are not allowed to define GUI stauses
    You are not allowed to enter a value for Next screen
    The global data of the program is not available for the subscreen. Data for the subscreen is provided by function modules. These function modules belongs to the same function group as the subscreen
    Subscreens are edited with transaction CMOD. When you activate a project containg subscreens, the calling screen is regenerated and the subscreen is displayed next time you display the calling screen
    The developer must create the subscreen and the corresponding PBO and PAI modules
    How to identify screen exits
    Look after CALL CUSTOMER-SUBSCREEN in the screenprogram of the screen you want to modify.
    Use transaction CMOD menu Utillities -> SAP enhancements to search for screen exits
    <b>MENU EXITS</b>
    Menu exits allow you to add your own functionallity to menus. Menu exits are implemented by SAP, and are reserved menu entries in the GUI interface. The developer can add his/her own text and logic for the menu.
    Function codes for menu exits all start with "+"
    Example
    We want to create a new menu item in the Office menu. The text for the menu should be "Run ZTEST", and the menu will
    run report ZTEST.
    Goto transaction SE43 Area Menu Maintenance
    In Area Menu Paramenter type 'S000' (S triple Zero)
    Select Change and ignore all the warning screens
    Expand the office menu. In the buttom of the office tree you will find a menu named "Customer function"
    Double click on the text. In the pop-up screen change the text to "Run ZTEST". Note that the trsnaction code is +C01
    Goto transaction SE93 and create transaction +C01 that calls report ZTEST.
    Now you will se the menu displayed in the office tree. If you delete transaction +C01 again, the new menu will dissapear.
    USER EXITS
    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 <3 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 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'.

  • Screen exit for me32k for header and for items

    hi experts,
    i need a screen exit  from me32k to add subscreen in :
    1. items
    2. header
    thanks in advanced,
    dana.

    Hi,
    Just some information on screen exits:
    Screen Exit:
    How to implement screen exit for a SAP standard transaction
    Introduction
    SAP provides standard transactions to enter data into database. But a client may want to maintain some additional information in SAP other than what is provided.
    To make provisions for this, additional screens have to be provided and additional fields must be added into appropriate database table.
    To pave way for this, SAP has provided the option for screen exits. Usually, SAP provides the following:
    An append structure in the database table with the new fields.
    A subscreen area into the standard screen – where the programmer can attach his subscreen of his own program with the new fields.
    A function group under which the new subscreen has to be created with the new fields.
    Function exits to synchronize the PBO and PAI of the standard SAP program with the PBO and PAI of the subscreen – so that data can flow back and forth between the standard SAP program and the program written by the developer for the subscreen. These function modules also exist in the same function group under which the subscreen will have to be developed.
    Finally, a linkage has to be done between the subscreen area of standard SAP screen with the custom subscreen constructed by the developer.
    Typically, SAP provides an enhancement in which the developer can create an append structure, use the function exits to synchronize the PBO and PAI of the standard SAP program and the custom subscreen program, and make the necessary linking( as mentioned above in step 4. But, again, this is not a hard and fast rule. Linking in some case, is also done by configurations.) SAP also usually provides the name of the function group under which the subscreen has to be developed.
    Necessary guidance about implementing a screen exit development is usually available in the Documentation section of the enhancement ( can be availed by transaction SMOD).
    Pre-Requisites
    The developer to work on screen exit should have essential knowledge on the following:
    DDIC concepts, including the knowledge of append structure.
    Concept of SAP Enhancements and implementing them using Projects.
    Concept of function exits.
    Knowledge on Module Pool – including subscreens, Tabstrip controls etc.
    Steps
    Guidelines
    So, a developer can follow the guidelines mentioned below to implement a screen exit to a standard SAP transaction, as and when required:
    Find out the Required Enhancements
    Go to SMOD. Press F4 in the Enhancement field. In the next popup window, click pushbutton ‘SAP Applications’. A list will appear that contains information on all the enhancements, categorized under functional areas. Developer must search for the enhancements relevant to his functional area of interest – for e.g., Purchasing, Asset Accounting, etc.
    Note down the enhancements. Then, come to the initial screen of SMOD and view the documentation of each enhancement to find out which one is required for your development.
    Utilize the Enhancement in a Project
    After you have found one, do as directed in the documentation. Generally, the steps are as follows:
    Create a project using CMOD including your enhancement.
    Create the append structure with new fields.
    Go to the desired function group and create a subscreen with the new fields. Write PBO and PAI for the subscreen, if required.
    Use the function exits in the enhancement to link the PBO and PAI of the subscreen with that of the main SAP program supporting the SAP transaction.
    Maintain necessary linkage between the subscreen area of standard SAP program with the custom subscreen developed along with the custom program name. This can be done in the project (developed by CMOD including the enhancement) or outside as a part of configuration.
    Activate the project.
    Test to ensure that required functionality are met.
    Case Study 1
    Add three new custom fields for Asset master and maintain information for them
    Requirement
    Three fields in the legacy system have to be maintained in Asset master. These fields are:
    Original Asset number – 20 characters
    Location 2 – 15 Characters.
    Model no – 20 characters
    Location 2 should start with ‘L’.
    Pre-Analysis
    Finding out the Enhancement
    As described above, the enhancement is determined. It was found, that enhancement AIST0002 will serve the purpose. It contains the following components (can be viewed by transaction SMOD):
    Exit Type Description EXIT_SAPL1022_001 Function Exit Check of User-Defined Fields when Using Create and Change BAPI EXIT_SAPLAIST_002 Function Exit Transfer Data for User Subscreens in PBO. EXIT_SAPLAIST_003 Function Exit Transfer of User-Defined Fields to SAP Master Data Transactions CI_ANLU Customizing Include Include structure to add new fields
    Studying the Function Exits
    The function module level documentation for the function exits are then viewed from transaction SE37. The documentation clearly laid out for the purpose for their use:
    EXIT_SAPLAIST_002
    Function module Level Documentation
    This function module is called by asset master data maintenance at the start of the dialog. (When changing, it is called after reading of the data from the database; when creating it is called after the transfer of the default values from the asset class and reference asset.) The purpose of the function module is to enable this function group to recognize the master data. For interpreting or controlling master data fields that are important for user fields, it is possible to transfer to global variables at this point, so that they can be recognized when the user subscreens are processed.
    Import Parameters
    Understanding
    This function module is called at the PBO to pass the information retrieved from the database to pass them to the custom subscreen and its underlying program. Import parameter : I_ANLU will be populated with the values for user-defined fields which will be passed to the subscreen program. So, there must be some sort of variable assignment from I_ANLU.
    EXIT_SAPLAIST_003
    Function module Documentation: This function module is called by SAP asset master data maintenance after the screens are processed, but before saving. The purpose of the function module is to transfer fields entered on user sub-screens of SAP asset data maintenance to the database for updating. The export parameter for this function module is:
    Understanding
    This function module will be used to transfer the user entered data in the subscreen fields to the main SAP program, which will then be saved into the database.
    Studying the Documentation of the Enhancement
    The enhancement documentation (as is viewed from the initial screen of SMOD] also supports the idea. Moreover, it informs that we need to develop a subscreen under function group XAIS. This is the function group under which the two function exit modules also exist. So, if the custom subscreen refers to the global data of the function group XAIS, then those values will also be available to these function exits as well.
    Going to SE80 and viewing the function group XAIS helps us to inform that there are three DDIC tables declared for it:
    Deciding the Final course of Action
    After making all the investigations, the final course of action was determined.
    SrlNo Step Justification
    A project has to be created using transaction CMOD where the enhancement AIST0002 will be included.
    Customizing include CI_ANLU has to be created with the custom fields demanded When CI_ANLU will be developed, the custom fields will get appended to the database table ANLU. Also, these fields will be used to create screen fields in the new subscreen.
    A custom subscreen, say, 9000 will be developed under function group XAIS. The screen group for the screen will be ‘CUST’ (or any name). The three custom fields added to table ANLU (by creating CI_ANLU) will be used to create new fields in the screen.
    In the PAI of the subscreen, validation for Location to start with ‘L’ will be added. The subscreen with three new fields has to be developed so that it can be attached to a subscreen area of the asset master screens.
    In the custom include of the function exit module ‘EXIT_SAPLAIST_002’, the following code will be written:-
    ANLU = I_ANLU. I_ANLU is the import parameter of this FM. The value is assigned to the global variable ANLU, referring which the three new subscreen fields are developed. So, data retrieved from database table ANLU will be passed to this FM as I_ANLU by the standard SAP main program. The value will be taken and passed to the global variable of the function group XAIS, so that the three custom fields (referring to ANLU of XAIS) get populated.
    In the custom include of the function exit module ‘EXIT_SAPLAIST_003’, the following code will be written:-
    E_ANLU = ANLU. The changed values in the subscreen fields exist in global variable ANLU for the function group XAIS. This function exit module will pass the data back to the SAP main program as E_ANLU.
    Proper linkage/configuration has to be done so that the new subscreens get linked to the appropriate subscreen area of the Asset master screen. This has to be done – otherwise, the new custom subscreen will not be displayed in the Asset master screens.
    Development
    Creating a Project to include the enhancement
    Go to transaction CMOD and create a project.
    Enter a description for the project. Then, click on the pushbutton ‘Enhancement Assignments’ in the Application Toolbar.
    Enter the name of the enhancement and Save.
    Go to ‘Components’.
    Creating Custom Include for ANLU
    The screen shown below will appear, showing all the enhancement components under the assignment AIST0002. Double-click on the name of the Include Structure to create it.
    Create the include structure with three new fields, as required. Then, save and activate it.
    Develop the subscreen and the program
    Go to transaction SE80. For the function group XAIS, create a new subscreen 9000.
    Create it as subscreen.
    Then, go to the Layout of the screen and create three new fields from Database table ANLU.
    Drag the fields in the screen body and place them.
    Then, save and activate the screen and come back to screen flow editor.
    Create the PAI module to add validation for field “Location 2”, as required .
    Activate the whole function group and come out.
    Write code in the Function Exits to synchronize the programs
    Now, code has to be written in the function modules EXIT_SAPLAIST_002 and EXIT_SAPLAIST_003 so that data flows to and fro between the main SAP program and custom subscreen program. For that, go back to transaction CMOD and change the function exits.
    Write code in the function module EXIT_SAPLAIST_002 called once at the beginning of the transaction:
    Write code in EXIT_SAPLAIST_003 to pass the data from the subscreen to SAP main program.
    Then, activate everything – the whole project and come out.
    Complete the configuration to link the subscreen
    The development portion is complete. Now, linking of the subscreen has to be done with the subscreen area of the main program. In most of the cases, this linking can be done in the enhancement itself. But, here, requirement is a bit different. It is done by configuration using SPRO.
    Assets are created under Asset class. And for each asset class, there is a layout assigned to it. For a layout, there are multiple tab pages assigned to it. And, for each tab page, there are multiple screen groups/field groups assigned.
    Here, the requirement is to create these three custom fields in the tab page ‘General’ of asset master screen ( AS01/AS02/AS03/AS91).
    Determine the Layout
    To achieve this, first of all, we need to find out which layout is assigned to asset class 1000.For that, go to transaction AOLK( information has to be obtained from functional consultant).Select the Asset Class ‘1000’ and click on folder ‘General Assignment of Layout’.
    Here, for Asset class 1000, for all the user groups, tab layout SAP is assigned. Since layout ‘SAP’ cannot be changed, it has to be copied and manipulated to include our screen group. Later, the new layout has to be assigned over here.
    Create new tab layout
    Go to transaction AOLA. Copy the tab layout ‘SAP’ to create another layout, say, YSUB.
    System will copy all the settings and will inform you about that.
    Select your newly created layout and double-click on the folder ‘Tab page titles’.
    You want to put your custom fields in the tab page “General”. So, select this tab page entry and double-click on the folder "Position of Groups".
    Here, all the field groups currently residing in the tab-page “General” are shown. Add an entry for your newly created fields.
    Select the group box from the list. An entry will come with “U” padded with the custom subscreen prepared by you.
    Then, save and come out.
    Assign the new Layout to Asset Class
    Now, go to tcode AOLK and assign tab layout YSUB for asset class 1000.
    Save and come out.
    Test the Exit
    Everything is over. Now, go to transaction code AS01/02/03 or AS91 to deal with an asset of asset class 1000. You will see your new fields added to the screen. Add values to them…save. Then, enter into the tcodes again to see whether the values entered by you are being displayed or not.

    User Exits:
    User exits (Function module 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 functionmodule exits is:
    EXIT_<program name><3 digit suffix>
    The call to a functionmodule exit is implemented as:
    CALL CUSTOMER.-FUNCTION <3 digit suffix>
    To find a Exit.
    Goto Transaction -- Find The Package
    SMOD >f4>Use the Package here to Find the Exits In the Package.
    Else if you Want to search by Application Area wise ,
    There is one more tab to find the Exits in the Respective Application Area.

  • Issues in screen exit

    Hi all,
    I am working on the requirement to print the work order attachments (tcode iw32).
    To achieve this functionality we have found out enhancement IWO10018, from which we are using function exit 'EXIT_SAPLCOIH_018' and screen exit SAPLXWOC screen 0900.
    So, for this i have written my code to retrieve attachment names in the function exit and created subscreen 0900 in function group XWOC.
    But now i am facing issues with how to link up the function exit with the screen exit?
    can anybody help me out please?
    Thanks,
    Archana

    Hi Archana,
    First create the project in CMOD.
    GOto Tcode > CMOD  create project

  • Screen exit step by step procedure

    Hi,
           This is Surya from Vizag.Can anyone tell me step by step procedure for creating a screen exit for a standard application.

    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.
    the tcode is cmod...
    Screen Exit is nothing but enhancing the screen like creating some more fields, subscreen and so on.
    1. Go to the screen>System>Status-->Program (Double click this program. It will take you to the program)
    2. Now, Goto-->Object Directory Entry.
    3. Make a note the package name.
    4. Now run the transactions SMOD, press F4 and enter theabove noted package, press enter.
    5. It will display list of Exits.
    6. Now go back to the initial screen SMOD.
    7. Specify the exit name here and select the radio button Components.
    8. It will display four group boxes one for FM, second for Fcodes, thrid for Screen areas and last for includes.
    9. Goto transaction CMOD, create a new project, andclick the button "Enhancement assignments" and specify your enhancements that you got in SMOD.
    10. Now bouble click the enhancement, it will take you to editor with some includes starting with Z, double clikc the include you want to edit and proceed.

    A custom subscreen, say, 9000 will be developed under function group XAIS. The screen group for the screen will be ‘CUST’ (or any name). The three custom fields added to table ANLU (by creating CI_ANLU) will be used to create new fields in the screen.
    In the PAI of the subscreen, validation for Location to start with ‘L’ will be added. The subscreen with three new fields has to be developed so that it can be attached to a subscreen area of the asset master screens.
    In the custom include of the function exit module ‘EXIT_SAPLAIST_002’, the following code will be written:-
    ANLU = I_ANLU. I_ANLU is the import parameter of this FM. The value is assigned to the global variable ANLU, referring which the three new subscreen fields are developed. So, data retrieved from database table ANLU will be passed to this FM as I_ANLU by the standard SAP main program. The value will be taken and passed to the global variable of the function group XAIS, so that the three custom fields (referring to ANLU of XAIS) get populated.
    In the custom include of the function exit module ‘EXIT_SAPLAIST_003’, the following code will be written:-
    E_ANLU = ANLU. The changed values in the subscreen fields exist in global variable ANLU for the function group XAIS. This function exit module will pass the data back to the SAP main program as E_ANLU.
    Proper linkage/configuration has to be done so that the new subscreens get linked to the appropriate subscreen area of the Asset master screen. This has to be done – otherwise, the new custom subscreen will not be displayed in the Asset master screens.
    Development
    Creating a Project to include the enhancement
    Go to transaction CMOD and create a project.
    Enter a description for the project. Then, click on the pushbutton ‘Enhancement Assignments’ in the Application Toolbar.
    Enter the name of the enhancement and Save.
    Go to ‘Components’.
    Creating Custom Include for ANLU
    The screen shown below will appear, showing all the enhancement components under the assignment AIST0002. Double-click on the name of the Include Structure to create it.
    Create the include structure with three new fields, as required. Then, save and activate it.
    Develop the subscreen and the program
    Go to transaction SE80. For the function group XAIS, create a new subscreen 9000.
    Create it as subscreen.
    Then, go to the Layout of the screen and create three new fields from Database table ANLU.
    Drag the fields in the screen body and place them.
    Then, save and activate the screen and come back to screen flow editor.
    Create the PAI module to add validation for field “Location 2”, as required .
    Activate the whole function group and come out.
    Write code in the Function Exits to synchronize the programs
    Now, code has to be written in the function modules EXIT_SAPLAIST_002 and EXIT_SAPLAIST_003 so that data flows to and fro between the main SAP program and custom subscreen program. For that, go back to transaction CMOD and change the function exits.
    Write code in the function module EXIT_SAPLAIST_002 called once at the beginning of the transaction:
    Write code in EXIT_SAPLAIST_003 to pass the data from the subscreen to SAP main program.
    Then, activate everything – the whole project and come out.
    Complete the configuration to link the subscreen
    The development portion is complete. Now, linking of the subscreen has to be done with the subscreen area of the main program. In most of the cases, this linking can be done in the enhancement itself. But, here, requirement is a bit different. It is done by configuration using SPRO.
    Assets are created under Asset class. And for each asset class, there is a layout assigned to it. For a layout, there are multiple tab pages assigned to it. And, for each tab page, there are multiple screen groups/field groups assigned.
    Here, the requirement is to create these three custom fields in the tab page ‘General’ of asset master screen ( AS01/AS02/AS03/AS91).
    Determine the Layout
    To achieve this, first of all, we need to find out which layout is assigned to asset class 1000.For that, go to transaction AOLK( information has to be obtained from functional consultant).Select the Asset Class ‘1000’ and click on folder ‘General Assignment of Layout’.
    Here, for Asset class 1000, for all the user groups, tab layout SAP is assigned. Since layout ‘SAP’ cannot be changed, it has to be copied and manipulated to include our screen group. Later, the new layout has to be assigned over here.
    Create new tab layout
    Go to transaction AOLA. Copy the tab layout ‘SAP’ to create another layout, say, YSUB.
    System will copy all the settings and will inform you about that.
    Select your newly created layout and double-click on the folder ‘Tab page titles’.
    You want to put your custom fields in the tab page “General”. So, select this tab page entry and double-click on the folder "Position of Groups".
    Here, all the field groups currently residing in the tab-page “General” are shown. Add an entry for your newly created fields.
    Select the group box from the list. An entry will come with “U” padded with the custom subscreen prepared by you.
    Then, save and come out.
    Assign the new Layout to Asset Class
    Now, go to tcode AOLK and assign tab layout YSUB for asset class 1000.
    Save and come out.
    Test the Exit
    Everything is over. Now, go to transaction code AS01/02/03 or AS91 to deal with an asset of asset class 1000. You will see your new fields added to the screen. Add values to them…save. Then, enter into the tcodes again to see whether the values entered by you are being displayed or not.

    Hi,
       You have to create SAPLXM02 0111  which is already getting called by the calling screen SAPLMEGUI 0014 so once you create this screen it should automatically come on the PR creation screen.

  • Screen Exits and Menu Exits

    Hi all,
    Can anyone help me with a step-by-step procedure or tutorial to create
    a) Screen exit
    b) Menu Exit...?
    Thanks and regards
    Shiva

    Hi Shiva,
    Check this...it will help u to create menu exit...
    Creating Customer-Specific Menus
    Menu exits allow you to add your own functions to the pulldown menus in standard R/3 transactions. To take advantage of a menu exit, you first need to create a project as described in the section Creating an add-on project. Then, you must include the SAP enhancement package that contains the menu exit you want to use in your project. From the main screen of the Project management transaction, proceed as follows:
    Select Enhancement components and choose Change.
    The system lists all customer exits contained in the enhancements included in your project.
    Place the cursor on the menu exit you want to add your own function to.
    Choose Edit component.
    The system displays technical information about the menu entry. It also displays two input fields where you can specify a language and the text you want your menu item to have.
    Enter the name of your menu function (such as Special order method) in the field New text.
    Choose Save text.
    Your special menu function will not appear in the pulldown menu of the corresponding standard transaction until you activate your enhancement project.
    Specifying a menu text and activating your project are not the only steps you need to take to make your own menu item work. After you carry out these steps, your menu item will appear, but it will not call a corresponding function. To attach your menu entry to its corresponding function, you need to create a function module for the function module exit associated with your menu text. This function module exit is part of the same SAP enhancement that contains the menu exit you used. Creating Customer-Specific Function Modules tells you more about how to use function module exits.
    Procedure for Creating MENU Exits:
    1) To get into Area Menu Maintenance Screen Type SE43 T.Code in Command
    Line.
    2) In Area Menu Paramenter type 'S000' (S triple Zero)
    3) Then Press Change Icon in Application Tool Bar. Then It may ask for
    Access Key [or] it may display "Specify Processing mode" window. If it ask
    for the Access Key Check for the availability of OSS Note and apply to open
    Standard SAP Menu to include MENU Exits. Otherwise, if it display "Specify
    Processing mode" window with Three Push Button. In which select "Change" and
    proceed further.
    4) Then it will display "Information" window with the following information
    "Caution : The Original Language of the structure is German (editing lang. :
    English) ". Then press "Enter Key to proceed further.
    5) Then you will get into "Edit Area Menu S000".
    6) for eg:- Expand Tools Menu.
    7) Then Press ABAP Workbench <Icon>.
    8) Then you will get into ABAP Workbench Menu Tree.
    9) Then Expand Utilities Menu.
    10) In the last line you will find one MENU EXIT Provision to include your
    own menu. "Node Text Not Found" This text can be change by double Clicking
    that. There you can find the T.Code. Here for Eg:- "+DW4".
    11) for eg: - Here change the Text to "Sample Menu Exit" and then note down
    the T.Code "+DW4".
    12) Then Save with Change Request Number and come out of Transaction SE43.
    13) Then Goto Transaction SE93.
    14) Then type T.Code "+DW4" and press Create.
    15) Then proceed further to create transaction called "+DW4".
    I hope this could help you in Creating Menu Exit...

  • DIfference Between User Exits, Screen Exits, Menu Exits And BADI

    Could any one let me know the exact/practical dIfference Between User Exits, Screen Exits, Menu Exits And BADI. ? And why BADIs are more proned to use?

    Hi,
    User Exits:
    A user exit is a three character code that instructs the system to access a program during system processing.
    SXX: S is for standard exits that are delivered by SAP.   XX represents the 2-digit exit number.
    UXX: U is for user exits that are defined by the user.  XX represents the 2-digit exit number
    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.
    BADIs:
    Business Add-Ins are a new SAP enhancement technique based on ABAP Objects. They can be inserted into the SAP System to accommodate user requirements too specific to be included in the standard delivery. Since specific industries often require special functions, SAP allows you to predefine these points in your software. 
    And why BADIs are more proned to use?
    In contrast to above customer exits, Business Add-Ins no longer assume a two-level infrastructure (SAP and customer solutions), but instead allow for a multi-level system landscape (SAP, partner, and customer solutions, as well as country versions, industry solutions, and the like). Definitions and implementations of Business Add-Ins can be created at each level within such a system infrastructure.
    SAP guarantees the upward compatibility of all Business Add-In interfaces. Release upgrades do not affect enhancement calls from within the standard software nor do they affect the validity of call interfaces. You do not have to register Business Add-Ins in SSCR.
    The Business Add-In enhancement technique differentiates between enhancements that can only be implemented once and enhancements that can be used actively by any number of customers at the same time. In addition, Business Add-Ins can be defined according to filter values. This allows you to control add-in implementation and make it dependent on specific criteria (on a specific Country value, for example).
    All ABAP sources, screens, GUIs, and table interfaces created using this enhancement technique are defined in a manner that allows customers to include their own enhancements in the standard. A single Business Add-In contains all of the interfaces necessary to implement a specific task.
    The actual program code is enhanced using ABAP Objects. In order to better understand the programming techniques behind the Business Add-In enhancement concept, SAP recommends reading the section on ABAP Objects.

    Ferry Lianto

  • Menu Exit  & Screen Exit Implementation Step by Step Implementation Needed:

    Thanks for your help in Advance.

    Hi Sudha,
    Screen exits are exits that allow you to use a reserved part of the screen (A subscreen) to display or input data.
    It is determined be SAP where the sub screen will be displayed.
    The syntax is: CALL CUSTOMER-SUBSCREEN
    The screen exit is not processed untill the corresponding subscreen has been created in an enhancement project, and the project has been activated.
    Note:
    Function codes are only processed in the main screens flow logic
    You are not allowed to enter a name for the subscreens command field
    You are not allowed to define GUI stauses
    You are not allowed to enter a value for Next screen
    The global data of the program is not available for the subscreen. Data for the subscreen is provided by function modules. These function modules belongs to the same function group as the subscreen
    Subscreens are edited with transaction CMOD. When you activate a project containg subscreens, the calling screen is regenerated and the subscreen is displayed next time you display the calling screen
    The developer must create the subscreen and the corresponding PBO and PAI modules
    How to identify screen exits
    Look after CALL CUSTOMER-SUBSCREEN in the screenprogram of the screen you want to modify.
    Use transaction CMOD menu Utillities -> SAP enhancements to search for screen exits
    MENU EXITS
    Menu exits allow you to add your own functionallity to menus. Menu exits are implemented by SAP, and are reserved menu entries in the GUI interface. The developer can add his/her own text and logic for the menu.
    Function codes for menu exits all start with "+"
    Example
    We want to create a new menu item in the Office menu. The text for the menu should be "Run ZTEST", and the menu will
    run report ZTEST.
    Goto transaction SE43 Area Menu Maintenance
    In Area Menu Paramenter type 'S000' (S triple Zero)
    Select Change and ignore all the warning screens
    Expand the office menu. In the buttom of the office tree you will find a menu named "Customer function"
    Double click on the text. In the pop-up screen change the text to "Run ZTEST". Note that the trsnaction code is +C01
    Goto transaction SE93 and create transaction +C01 that calls report ZTEST.
    Now you will se the menu displayed in the office tree. If you delete transaction +C01 again, the new menu will dissapear.
    USER EXITS
    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 <3 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 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 craete a salesorder. Note that Sold-to-party now automatically is "2155"
    Please check if the thread given below would be of any help.
