BDC and BAPI

Hi Experts!!
I wanted to know why we use BDC since we have BAPI's by which we can upload the data too.
Please let me know the reson going for BDC instead of BAPI for any transaction.

Its not that in certain cases BAPIs cannot upload data properly.
In certain cases BAPIs are not available and hence we may make use of BDC to upload data.
BAPIs are faster to load data than a BDC, if both the options exist.
You could google this to get numerous hits on the difference between the two.

  • ABAP interfaces build using BDC and BAPIs can be used/replaced with the XI?

    Hi,
      We have develeloped our interfases using BDC and BAPIs. Now our client has decited to implement XI. Now could you please help in finding whether these interfaces can be used/replaced with the XI.
          If yes, please let us know how?

  • Diffrence between BDC and BAPI's

    Hi all
    can any one tell me when to go with BDC and when to BAPI
    rewards are expected

    Hai Sai
    Check the following Differences B/W BDC and BAPI
    The steps to be followed are :
    1. Find out the relevant BAPI (BAPI_SALESORDER_CHANGE for VA02).
    [for VA01 use BAPI_SALESORDER_CREATEFROMDAT2]
    2. Create a Z program and call the BAPi (same as a Funtion module call).
    2. Now, if you see this BAPi, it has
    -> Importing structures.
    eg: SALESDOCUMENT: this will take the Sales order header data as input.
    -> Tables parameters:
    eg: ORDER_ITEM_IN: this will take the line item data as input.
    Note :
    Only specify fields that should be changed
    Select these fields by entering an X in the checkboxes
    Enter a U in the UPDATEFLAG field
    Always specify key fields when changing the data, including in the checkboxes
    The configuration is an exception here. If this needs to be changed, you need to complete it again fully.
    Maintain quantities and dates in the schedule line data
    Possible UPDATEFLAGS:
    U = change
    D = delete
    I = add
    Example
    1. Delete the whole order
    2. Delete order items
    3. Change the order
    4. Change the configuration
    Notes
    1. Minimum entry:
    You must enter the order number in the SALESDOCUMENT structure.
    You must always enter key fields for changes.
    You must always specify the update indicator in the ORDER_HEADER_INX.
    2. Commit control:
    The BAPI does not run a database Commit, which means that the application must trigger the Commit so that the changes are read to the database. To do this, use the BAPI_TRANSACTION_COMMIT BAPI.
    For further details... refer to the Function Module documentation for the BAPi.

  • Diffrent between BDC and BAPI

    Gurus..
    Please let know what is the diffrent between BAPI and BDC development?

    Hi
    BDC:
    Batch Data Communication (BDC) is the process of transferring data from one SAP System to another SAP system or from a non-SAP system to SAP System.
    Features :
    BDC is an automatic procedure.
    This method is used to transfer large amount of data that is available in electronic medium.
    BDC can be used primarily when installing the SAP system and when transferring data from a legacy system (external system).
    BDC uses normal transaction codes to transfer data.
    Types of BDC :
    CLASSICAL BATCH INPUT (Session Method)
    CALL TRANSACTION
    BAPI stands for Business API(Application Program Interface).
    A BAPI is remotely enabled function module ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
    You can make your function module remotely enabled in attributes of Function module but
    A BAPI are standard SAP function modules provided by SAP for remote access. Also they are part of Businees Objest Repository(BOR).
    BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects. You create business objects and those are then registered in your BOR (Business Object Repository) which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in this case u only specify the business object and its method from external system in BAPI there is no direct system call. while RFC are direct system call Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.
    The following standardized BAPIs are provided:
    Reading instances of SAP business objects
    GetList ( ) With the BAPI GetList you can select a range of object key values, for example, company codes and material numbers.
    The BAPI GetList() is a class method.
    GetDetail() With the BAPI GetDetail() the details of an instance of a business object type are retrieved and returned to the calling program. The instance is identified via its key. The BAPI GetDetail() is an instance method. BAPIs that can create, change or delete instances of a business object type
    The following BAPIs of the same object type have to be programmed so that they can be called several times within one transaction. For example, if, after sales order 1 has been created, a second sales order 2 is created in the same transaction, the second BAPI call must not affect the consistency of the sales order 2. After completing the transaction with a COMMIT WORK, both the orders are saved consistently in the database.
    Create( ) and CreateFromData! ( )
    The BAPIs Create() and CreateFromData() create an instance of an SAP business object type, for example, a purchase order. These BAPIs are class methods.
    Change( )
    The BAPI Change() changes an existing instance of an SAP business object type, for example, a purchase order. The BAPI Change () is an instance method.
    Delete( ) and Undelete( ) The BAPI Delete() deletes an instance of an SAP business object type from the database or sets a deletion flag.
    The BAPI Undelete() removes a deletion flag. These BAPIs are instance methods.
    Cancel ( ) Unlike the BAPI Delete(), the BAPI Cancel() cancels an instance of a business object type. The instance to be cancelled remains in the database and an additional instance is created and this is the one that is actually canceled. The Cancel() BAPI is an instance method.
    Add<subobject> ( ) and Remove<subobject> ( ) The BAPI Add<subobject> adds a subobject to an existing object inst! ance and the BAPI and Remove<subobject> removes a subobject from an object instance. These BAPIs are instance methods.

  • Disadvantages of Using BDC over BAPI

    Hello ,
    could you please clear my confusion as why BDC are not supposed to be used for data uploading over bapis.
    What are the advantages and disadvantages between BDC and BAPI
    thanks in Advance
    PAvan

    Hi Pavan,
    BDC is slower because it additionally processes the screens. This is a big disadvantage (could be more than 10 times slower). An advantage on BDC processing is that you can later view an process the data manually.
    With BAPIs (which are not necessarily OO) you have to have some error handling in place if one of the imported data sets fails (sometimes done with restartable jobs, look for example into the documentation of RFBIBL00).
    Also, as already mentioned, changes of the screen layout and/or the GUI status will very likely make your BDC sessions fail (no matter these changes were caused by customising settings or a patch).

  • Screen exit and bapi

    how can we call a subscreen in screen exit.
    how can we do error handling in bapi?differenece between bapi and bdc.
    i will give the 10points to correct answers.
    kiran

    Hi,
      Call subscreen in screen exit:
    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

  • Can anyone list problems/errors when uploading data using BDC's and BAPI's?

    Can anyone list the problems/errors when uploading data using BDC's and BAPI's?

    Hi,
    If you are actually creating a BDC to load data pls be more specific.
    Data format incorrect. Tab delimited/ etc
    Dates in wrong formats
    Currency incorrect formats
    Missing screens
    Wrong transaction code
    File not found,
    Missing Mandatory fields,
    Screen resoultion.
    You should always use refresh for your Bdcdata table.
    Loop at internal table.
    refresh Bdcdata.

  • Help with BDC, user exits and BAPI

    Hello all:
    1) I posted a question before about BDC documentation and people sent me lot of helpful material. Thanks to all of them. I am very new to ABAP coming from VB background and wondering if someone can tell me how to practice one simple BDC program starting from scratch. What do I first need to do to get started? I have Mini WAS 6.20 test version and like to practice BDC programming.
    2) What are user exits and BADI and can anyone provide some documentation and sample code if possible.
    Thanks everyone in advance.

    What is BDC or batch input
    The Batch Input is a SAP technic that allows automating the input in transactions. It lies on a BDC (Batch Data Commands) scenario.
    BDC functions:
    E BDC_OPEN_GROUP : Opens a session group
    E BDC_CLOSE_GROUP : Closes a session
    E BDC_INSERT : Insert a BDC scenario in the session
    E The ABAP statement "CALL TRANSACTION" is also called to run directly a transaction from its BDC table.
    It runs the program RSBDCSUB in order to launch automatically the session. The session management is done through the transaction code SM35.
    The object itself is maintanable through the transaction SE24.
    BDC methods:
    Method
    Description
    Parameters
    OPEN_SESSION
    Opens a session
    SUBRC (Return Code ? 0 OK)
    SESSIONNAME (Session to be created)
    CLOSE_SESSION
    Closes a session
    None
    RESET_BDCDATA
    Resets the BDC Internal Table...
    None. Normally, for internal purposec
    BDC_DYNPRO
    Handles a new screen
    PROGNAME (Name of the program)
    DYNPRONR (Screen Number)
    BDC_FIELD
    Puts a value on the screen
    FIELDNAME (Name of the field)
    FIELDVALUE (Value to be passed)
    CONSTRUCTOR
    Constructor - Initializes NO_DATA
    NODATA (No data character). The constructor is called automatically when the object is created.
    RUN_SESSION
    Launches a session with RSBDCBTC
    None
    CALL_TRANSACTION
    Calls a transaction with the current BDC Data
    MODE (Display Mode)
    UPDATE (Update Mode)
    TCODE (Transaction to be called)
    BDC_INSERT
    Inserts the BDC scenario in the session
    TCODE (Transaction to be called)
    BDC techniques used in programs:
    1) Building a BDC table and calling a transaction,
    2) Building a session and a set of BDC scenarios and keeping the session available in SM35,
    3) Building a session and lauching the transaction right after closing the session.
    BDC using Call Transaction
    BDC using Call transaction involves calling an SAP transaction in back ground from within the ABAP
    program. The process involves building an Internal BDC table containing the screen information needed to
    execute the required transaction and then passing this to the Call transaction command (See code example).
    The full procedure for creating a BDC program is as follows:
    What is the difference between batch input and call transaction in BDC?
    Session method.
    1) synchronous processing.
    2) can tranfer large amount of data.
    3) processing is slower.
    4) error log is created
    5) data is not updated until session is processed.
    Call transaction.
    1) asynchronous processing
    2) can transfer small amount of data
    3) processing is faster.
    4) errors need to be handled explicitly
    5) data is updated automatically
    BATINPUT/DIRECT INPUT
    A: Batch-inputs can not be used to fill the "delivery due list" screen because it is not a dynpro. This is a standard SAP report. A SAP report (check with "System -> Status") may be called using SUBMIT sentence with the appropriate options . It is preferred to call a report than create a Batch-input program.

    For User Exits
    User Exits
    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"

    Creation of Field Exits
    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
    - Before you can begin adding the functionality for a field exit, you must know the corresponding data element.
    - 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 eF1f for field-level help.
    Click on the eTechnical infof pushbutton (or press eF9f) 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
    - The transaction to create field exits is CMOD.
    - You can use the menu path Tools -> ABAP/4 Workbench -> Utilities -> Enhancements -> Project management.
    - From the initial screen of transaction CMOD, choose the Text enhancements -> Field exits menu path.
    - 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
    - From the field exit screen of transaction CMOD, choose the Field exit -> Create menu path.
    - After choosing this menu path, a dialog box will prompt you for the appropriate data element .
    - Enter the data element name and click the eContinuef pushbutton.
    - Now, you will be able to create the function module associated to the data elementfs field exit.
    Step 4: Create Function Module
    - You will automatically be taken to the Function Library (SE37) after entering a data element name and clicking the eContinuef pushbutton.
    - In the eFunction modulef 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_<data element>
    - You can add an identifier (an underscore followed by a single character ).
    - The first function module for a data elementfs field exit must be created without an identifier.
    - To create the function module, click on the eCreatef pushbutton, choose menu path Function module -> Create, or press eF5f.
    - 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 eEnterf, you will be able to go ahead and create the function module.
    - 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
    - From the function modulefs attributes screen, click on the eSource codef pushbutton or choose the Goto -> Function module menu path to the code of the function module.
    - Here you will add your desired functionality for the field exit.
    - Remember that field exitfs 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.
    - 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
    - After coding the function module, you must remember to activate it.
    - Use the Function module -> Activate menu path to activate the function module.
    - At this point, you can return to the field exit transaction.
    - You should be able to 'green arrow' back to this transaction.
    - When you return to the field exit transaction, you will see an entry for the newly created field exit.
    - 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.
    - Also, the field exit will not be triggered yet because it is inactive.
    Step 7: Assign Program/Screen
    - This step is only needed if you want to make a field exit local.
    - To make a field exit local, select the field exit and click on the eAssign prog./screenf pushbutton.
    - 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.
    - In the dialog box, you determine which function module gets executed for the field exit by specifying the identifier in the eFld. Exitf field.
    - If this field is left blank, the function module triggered will be 'FIELD_EXIT_<data element>'.
    - If a single-character identifier is entered into the field, the function module triggered will be 'FIELD_EXIT_<data element>_<identifier>'.
    Step 8: Activate Field Exit
    - The field exit must be active for it to be triggered by the system.
    - Activate the field exit by choosing the Field exit -> Activate menu path.
    - After assigning the field exit to a change request, its status will change to eActivef 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

  • Diff b/w BDC and LSMW

    hi
    i want know what is the difference between BDC and LSMW and which is best also tell me BDC and LSMW using for which type data (like master or transactional data)
    thanka in advance
    deepak

    Hi deepak,
    LSMW and BDC are vastly different.
    BDC (Batch Data Communication) is a technology used for data transfer. it is meant for transferring data thru SAP transactions itself. when u use BDC for data transfer, the sequence of steps is the same as when u use standard sap transaction screens for data upload. the only difference is that u can use different options for foreground/background processing.
    LSMW on the other hand is a tool that helps migrate data from a legacy system (non-sap system ) to SAP system. it offers u various options to use either batch input, direct input, BAPIs or idocs. it involves a series of some 17-18 steps to migrate data.
    BDC:
    Batch Data Communication (BDC) is the process of transferring data from one SAP System to another SAP system or from a non-SAP system to SAP System.
    Features :
    BDC is an automatic procedure.
    This method is used to transfer large amount of data that is available in electronic medium.
    BDC can be used primarily when installing the SAP system and when transferring data from a legacy system (external system).
    BDC uses normal transaction codes to transfer data.
    Types of BDC :
    CLASSICAL BATCH INPUT (Session Method)
    CALL TRANSACTION
    BATCH INPUT METHOD:
    This method is also called as ‘CLASSICAL METHOD’.
    Features:
    Asynchronous processing.
    Synchronous Processing in database update.
    Transfer data for more than one transaction.
    Batch input processing log will be generated.
    During processing, no transaction is started until the previous transaction has been written to the database.
    CALL TRANSACTION METHOD :
    This is another method to transfer data from the legacy system.
    Features:
    Synchronous processing. The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.
    Updating the database can be either synchronous or asynchronous. The program specifies the update type.
    Transfer data for a single transaction.
    Transfers data for a sequence of dialog screens.
    No batch input processing log is generated.
    For BDC:

    LSMW:
    The LSM Workbench is an R/3-based tool that supports You when transferring data from non-SAP systems ("Legacy Systems") to R/3 once or periodically.
    The tool supports conversion of data of the legacy system in a convenient way. The data can then be imported into the R/3 system via batch input, direct input, BAPIs or IDocs.
    Furthermore, the LSM Workbench provides a recording function that allows to generate a "data migration object" in an entry or change transaction.
    The main advantages of the LSM Workbench:
    • Part of R/3 and thus independent of individual platforms
    • A variety of technical possibilities of data conversion:
    • Data consistency due to standard import techniques:
    Batch input
    Direct input
    BAPIs (Business Application Programming Interfaces)
    IDocs (Intermediate Documents)
    The import technique to be used in an individual case depends on the business object.
    • Generation of the conversion program on the basis of defined rules
    • Clear interactive process guide
    • Interface for data in spreadsheet format
    • Creation of data migration objects on the basis of recorded transactions
    • Charge-free for SAP customers and SAP partners

  • BDC Using BAPI

    Hi All,
    Pls Send me sample code for using Bapi in a Bdc Program to upload Flat file
      (non-SAP)   Data into SAP R/3 .
    Rgds
    Rafi .

    Hi
    You can straight use a BAPI and upload the data into SAP like how you do using a BDC program.
    see the doc
    BAPI - BAPIs (Business Application Programming Interfaces) are the standard SAP interfaces. They play an important role in the technical integration and in the exchange of business data between SAP components, and between SAP and non-SAP components. BAPIs enable you to integrate these components and are therefore an important part of developing integration scenarios where multiple components are connected to each other, either on a local network or on the Internet.
    BAPIs allow integration at the business level, not the technical level. This provides for greater stability of the linkage and independence from the underlying communication technology.
    LSMW- No ABAP effort are required for the SAP data migration. However, effort are required to map the data into the structure according to the pre-determined format as specified by the pre-written ABAP upload program of the LSMW.
    The Legacy System Migration Workbench (LSMW) is a tool recommended by SAP that you can use to transfer data once only or periodically from legacy systems into an R/3 System.
    More and more medium-sized firms are implementing SAP solutions, and many of them have their legacy data in desktop programs. In this case, the data is exported in a format that can be read by PC spreadsheet systems. As a result, the data transfer is mere child's play: Simply enter the field names in the first line of the table, and the LSM Workbench's import routine automatically generates the input file for your conversion program.
    The LSM Workbench lets you check the data for migration against the current settings of your customizing. The check is performed after the data migration, but before the update in your database.
    So although it was designed for uploading of legacy data it is not restricted to this use.
    We use it for mass changes, i.e. uploading new/replacement data and it is great, but there are limits on its functionality, depending on the complexity of the transaction you are trying to replicate.
    The SAP transaction code is 'LSMW' for SAP version 4.6x.
    Check your procedure using this Links.
    BAPI with LSMW
    http://esnips.com/doc/ef04c89f-f3a2-473c-beee-6db5bb3dbb0e/LSMW-with-BAPI
    For document on using BAPI with LSMW, I suggest you to visit:
    http://www.****************/Tutorials/LSMW/BAPIinLSMW/BL1.htm
    what is BAPI?
    BAPI stands for Business API(Application Program Interface).
    A BAPI is remotely enabled function module ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
    You can make your function module remotely enabled in attributes of Function module but
    A BAPI are standard SAP function modules provided by SAP for remote access. Also they are part of Businees Objest Repository(BOR).
    BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects. You create business objects and those are then registered in your BOR (Business Object Repository) which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in this case u only specify the business object and its method from external system in BAPI there is no direct system call. while RFC are direct system call Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.
    The following standardized BAPIs are provided:
    Reading instances of SAP business objects
    GetList ( ) With the BAPI GetList you can select a range of object key values, for example, company codes and material numbers.
    The BAPI GetList() is a class method.
    GetDetail() With the BAPI GetDetail() the details of an instance of a business object type are retrieved and returned to the calling program. The instance is identified via its key. The BAPI GetDetail() is an instance method. BAPIs that can create, change or delete instances of a business object type
    The following BAPIs of the same object type have to be programmed so that they can be called several times within one transaction. For example, if, after sales order 1 has been created, a second sales order 2 is created in the same transaction, the second BAPI call must not affect the consistency of the sales order 2. After completing the transaction with a COMMIT WORK, both the orders are saved consistently in the database.
    Create( ) and CreateFromData! ( )
    The BAPIs Create() and CreateFromData() create an instance of an SAP business object type, for example, a purchase order. These BAPIs are class methods.
    Change( )
    The BAPI Change() changes an existing instance of an SAP business object type, for example, a purchase order. The BAPI Change () is an instance method.
    Delete( ) and Undelete( ) The BAPI Delete() deletes an instance of an SAP business object type from the database or sets a deletion flag.
    The BAPI Undelete() removes a deletion flag. These BAPIs are instance methods.
    Cancel ( ) Unlike the BAPI Delete(), the BAPI Cancel() cancels an instance of a business object type. The instance to be cancelled remains in the database and an additional instance is created and this is the one that is actually canceled. The Cancel() BAPI is an instance method.
    Add<subobject> ( ) and Remove<subobject> ( ) The BAPI Add<subobject> adds a subobject to an existing object inst! ance and the BAPI and Remove<subobject> removes a subobject from an object instance. These BAPIs are instance methods.

    Bdc to Bapi
    The steps to be followed are :
    1. Find out the relevant BAPI (BAPI_SALESORDER_CHANGE for VA02).
    [for VA01 use BAPI_SALESORDER_CREATEFROMDAT2]
    2. Create a Z program and call the BAPi (same as a Funtion module call).
    2. Now, if you see this BAPi, it has
    -> Importing structures.
    eg: SALESDOCUMENT: this will take the Sales order header data as input.
    -> Tables parameters:
    eg: ORDER_ITEM_IN: this will take the line item data as input.
    Note :
    Only specify fields that should be changed
    Select these fields by entering an X in the checkboxes
    Enter a U in the UPDATEFLAG field
    Always specify key fields when changing the data, including in the checkboxes
    The configuration is an exception here. If this needs to be changed, you need to complete it again fully.
    Maintain quantities and dates in the schedule line data
    Possible UPDATEFLAGS:
    U = change
    D = delete
    I = add
    Example
    1. Delete the whole order
    2. Delete order items
    3. Change the order
    4. Change the configuration
    Notes
    1. Minimum entry:
    You must enter the order number in the SALESDOCUMENT structure.
    You must always enter key fields for changes.
    You must always specify the update indicator in the ORDER_HEADER_INX.
    2. Commit control:
    The BAPI does not run a database Commit, which means that the application must trigger the Commit so that the changes are read to the database. To do this, use the BAPI_TRANSACTION_COMMIT BAPI.
    For further details... refer to the Function Module documentation for the BAPi.
    Bapi to VB(Visual Basic)
    Long back I had used the following flow structure to acheive the same.
    Report -> SM59 RFC destination -> COM4ABAP -> VB.exe
    my report uses the rfc destination to create a COM session with com4abap. com4abap calls the vb.exe and manages the flow of data between sap and vb exe.
    You need to have com4abap.exe
    If com4abap is installed you will find it in sapgui installatin directory , C:\Program Files\SAPpc\sapgui\RFCSDK\com4abap.
    else refer OSS note 419822 for installation of com4abap
    after making the settings in com4abap to point to the vb program and setting up rfc destination in sm59 to point to com4abap session , you can use the following function modules to call the vb code.
    for setting up com4abap and rfc destination please refer to the documentation for com4abap.
    Invoke NEW DCOM session
    call function 'BEGIN_COM_SESSION'
    exporting
    service_dest = service_dest "(this will be a RFC destination created in SM59)

  • Bdc,lsmw,bapi

    hello all,
    please tell me about difference between bdc , lsmw, bapi
    Moderator Message: Search for available information before posting.
    Edited by: kishan P on Dec 28, 2010 4:32 PM

    Hi Karthik,
    All the 3 can be used for the same purpose.
    BDC - was the first provided by SAP for mass data entry in to SAP Database with Screen checks
    LSMW - Originated as a 3rd party tool with many more functionalities and ease of use
    BAPI - Some times the transaction screens changes, in those cases the BDC's fail as they purely refer to the screen elements. BAPI's provide a more consistent way to make entries in SAP systems without referencing the screen elements but still adhering to the underlying business logic, so the data entry is syntactically and semantically correct.
    Hope this helps.
    Regards,
    Gaurav

  • Data migration ALE or idocs and bapis

    hi ,
    thank you guys for the support.
    i am into a data migration project.
    i need the initial setup for the idocs and bapis.
    i dont know anything about these so can u send me the process for the setup and the data migration process too with idocs and bapis.
    i didnt understand when they asked me if we can data migrate with a ALE, is that the same as using idocs and bapis or is it a different approach.
    u can send me at any inofrmation connected to my eamil addr.
    i would really appreciate that.
    thank you.

    Hi,
    Outbound:
    Step 1. Application document is created when transaction is saved.
    2. Message control is invoked.
    3. Messages are processed by system.
    4. Messages are Edited (if desired).
    5. Output (ALE / EDI) is checked
    6. Validate against Message control record from Partner Profile
    7. Application Document is saved.
    8. Entry NAST table is created for every selected output program
    along with Medium & Timing.
    9. Check for Process Immediately .
    If (yes)
    Determine Processing Program from TNAPR Table.
    ELSE
    Execute RSNASTED Program.
    10. Read Partner Profile to determine Process Code.
    11. Process Code points to the Function Module & Invoked.
    12. IDoc is generated.
    13. Check for ALE Request.
    if (Yes)
    Perform Filters, Conversions, Version Changes etc.
    Else.
    IDoc is stored in DATABASE.
    INBOUND:
    Step 1. EDI Subsystem creates an IDoc file from EDI Messages
    2. Subsystem calls Functional Module EDI_DATA_INCOMING from startRFC program.
    3. Data in Control Record is validate against the Partner Profile.
    4. IDoc is generated in Database and syntax check is carried out.
    5. IDoc file is deleted once file read.
    6. Event PROCESSSTATE REACHED is triggered in Idoc Object Workflow.
    7. Check for Process Immediately.
    If NO
    Execute RBDAPP01 Program
    Else
    Read Process Code from Partner Profile
    Process Code Points to Function Module
    Application Document Posted.

    The BAPIs Create() and CreateFromData() create an instance of an SAP business object type, for example, a purchase order. These BAPIs are class methods.
    Change( )
    The BAPI Change() changes an existing instance of an SAP business object type, for example, a purchase order. The BAPI Change () is an instance method.
    Delete( ) and Undelete( ) The BAPI Delete() deletes an instance of an SAP business object type from the database or sets a deletion flag.
    The BAPI Undelete() removes a deletion flag. These BAPIs are instance methods.
    Cancel ( ) Unlike the BAPI Delete(), the BAPI Cancel() cancels an instance of a business object type. The instance to be cancelled remains in the database and an additional instance is created and this is the one that is actually canceled. The Cancel() BAPI is an instance method.
    Add<subobject> ( ) and Remove<subobject> ( ) The BAPI Add<subobject> adds a subobject to an existing object inst! ance and the BAPI and Remove<subobject> removes a subobject from an object instance. These BAPIs are instance methods.

    Bdc to Bapi
    The steps to be followed are :
    1. Find out the relevant BAPI (BAPI_SALESORDER_CHANGE for VA02).
    for VA01 use BAPI_SALESORDER_CREATEFROMDAT2
    2. Create a Z program and call the BAPi (same as a Funtion module call).
    2. Now, if you see this BAPi, it has
    -> Importing structures.
    eg: SALESDOCUMENT: this will take the Sales order header data as input.
    -> Tables parameters:
    eg: ORDER_ITEM_IN: this will take the line item data as input.
    Note :
    Only specify fields that should be changed
    Select these fields by entering an X in the checkboxes
    Enter a U in the UPDATEFLAG field
    Always specify key fields when changing the data, including in the checkboxes
    The configuration is an exception here. If this needs to be changed, you need to complete it again fully.
    Maintain quantities and dates in the schedule line data
    Possible UPDATEFLAGS:
    U = change
    D = delete
    I = add
    Example
    1. Delete the whole order
    2. Delete order items
    3. Change the order
    4. Change the configuration
    Notes
    1. Minimum entry:
    You must enter the order number in the SALESDOCUMENT structure.
    You must always enter key fields for changes.
    You must always specify the update indicator in the ORDER_HEADER_INX.
    2. Commit control:
    The BAPI does not run a database Commit, which means that the application must trigger the Commit so that the changes are read to the database. To do this, use the BAPI_TRANSACTION_COMMIT BAPI.
    For further details... refer to the Function Module documentation for the BAPi.
    Bapi to VB(Visual Basic)
    Long back I had used the following flow structure to acheive the same.
    Report -> SM59 RFC destination -> COM4ABAP -> VB.exe
    my report uses the rfc destination to create a COM session with com4abap. com4abap calls the vb.exe and manages the flow of data between sap and vb exe.
    You need to have com4abap.exe
    If com4abap is installed you will find it in sapgui installatin directory , C:\Program Files\SAPpc\sapgui\RFCSDK\com4abap.
    else refer OSS note 419822 for installation of com4abap
    after making the settings in com4abap to point to the vb program and setting up rfc destination in sm59 to point to com4abap session , you can use the following function modules to call the vb code.
    for setting up com4abap and rfc destination please refer to the documentation for com4abap.
    Invoke NEW DCOM session
    call function 'BEGIN_COM_SESSION'
    exporting
    service_dest = service_dest "(this will be a RFC destination created in SM59)
    importing
    worker_dest = worker_dest
    exceptions
    connect_to_dcom_service_failed = 1
    connect_to_dcom_worker_failed = 2
    others = 3.
    call function 'create_com_instance' destination worker_dest
    exporting
    clsid = g_c_clsid
    typelib = g_c_typelib
    importing
    instid = g_f_oid
    exceptions
    communication_failure = 1 message g_f_msg
    system_failure = 2 message g_f_msg
    invalid_instance_id = 3
    others = 4.
    call function 'com_invoke' destination worker_dest
    exporting
    %instid = g_f_oid
    %method = 'UpdatePDF'
    sntemp = g_v_const_filent
    snsysid = sy-sysid
    snflag = 'N'
    tables
    rssaptable = g_t_pdfdetail1
    %return = g_t_pdfdetail1 "t_test
    exceptions
    communication_failure = 1 message g_f_msg
    system_failure = 2 message g_f_msg
    invalid_instance_id = 3
    others = 4.
    then close the com session , using
    FM delete_com_instance
    FM END_COM_SESSION
