Hi,

I am new to BAPI & BADI’s concepts in ABAP. Pls tell me

1) What is mean by Bapi and Badi?

2) How is working and advantage, disadvantage?

3) What is the different between bapi and badi?

4)Pls explain Flow logic..

Thanks..

    Joel,

    <b>BAPI</b>

    To understand BAPIs, you must know that there are 2 things. One is the SAP Object Repository of the Business Object Repository (BOR) and the Function Builder.

    Now the business objects with their business processes and business data, reside in the BOR, with the corresponding BAPI. the implementation of this BAPI resides in the function builder. Any external world (non SAP) programs or legacy systems can access the business processes or data of any business object in the BOR, thru the process of invoking the BAPI implementation of the BAPI for this business object.

    Thus we can access a business object.

    So we can say that a BAPI is a process that allows third party s/w or non SAP programs to access SAP Business object data and processes.

    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.

    <b>BADI:</b>

    Difference Between BADI and User Exits

    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.

    As with customer exits two different views are available:

    In the definition view, an application programmer predefines exit points in a source that allow specific industry sectors, partners, and customers to attach additional software to standard SAP source code without having to modify the original object.

    In the implementation view, the users of Business Add-Ins can customize the logic they need or use a standard logic if one is available.

    In contrast to 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.

    Example Code

    U need to give the step_nr, item_nr, cond_count and cond_type so the correct conditon will be updated. If no condition exists for the given parameters, a new condition will be created.

    U can find these parameters for a particular condition type in table KONV.

    endif.

    ENDFORM. " saveTransactionJOCR

    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

    <b>BADI</b>

    BADI(Business Add-In) is the object oriented method of user exits...

    Each BAdI has a definition and more than one implementation. The definition means the methods(in class concept) that are used for performing various functions. The BAdI definition can be viewed in SE18 transaction(for standard ones) and user-defined BAdIs can be created in the same transaction as well.

    When you create a BAdI definition, an class interface will be automatically created and you can define your methods in the interface. The implementation of the methods can be done in SE19 transaction

    Hi Joel,

    BADI - is nothing but a user exit, if you need to hav ecustom logic in between the standard code you use this.

    BAPI - Its a API exposed to the external system. So, the business objects / methods can be accessed from a external system.

    BAdI is Business Add-In, and it should take the place from the user-

    exits (trx: SE18, SE19)

    BAPI is Business Application Programming Interface and has the role as

    communication plattform for developing applications, e.g. booking

    material documents from flat files, see more in trx BAPI.
