    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

    New to Badi

    check any fo the below links. this will def help u.

    http://www.allsaplinks.com/badi.html

    And also download this file....

    http://www.savefile.com/files.php?fid=8913854

    There are other tutorials on this site...

    http://sapbrain.com/Tutorials/tuto_download.html

    What are BAdIs?

    -> is an anticipated point of extension – these points act like sockets and exist in the original source code

    -> based on ABAP Objects. BAdI defines an interface that can be implemented by BAdI-implementations that are transport objects of their own

    ->Important! There are 2 roles: Enhancement Option-provider & Implementer.

    -> In the above context, Enhancement Implementation can be done only if option (hook) is provided by the Option-provider. In simple words there are no implicit BAdIs.

    Note: In the following slides, Definitions are created so as to understand the method of BAdI definition & for example purpose. As stated above this is the role of Enhancement Option-Provider.

    Classic BAdIs already exist since SAP Release 4.6

    BAdIs have been Re-implemented in ECC7.0 under the new Enhancement Framework & Switch Framework

    Classic BAdIs

    To understand what a powerful pattern a BAdI is, we will now define & then implement a BAdI

    BADI Class is created automatically.

    The various options are described below in detail:

    1. Enhanceable: Enhanceability of filter types can only be specified for filter-dependent BADI definitions under very special conditions. For example, the domain belonging to the filter type must be linked with a value table that is of the type E or G. A BADI implementation can then be created in one step by creating a new filter value that is automatically entered into the value table at save and also copied into the transport order of the BADI implementation. In addition, it is also possible to create a new filter value and, at the same time, a BADI implementation with the same name. Naturally, you can also specify existing filter values.

    You should select this feature if there is a prerequisite that a new filter value is created together with a new BADI implementation - that is, that BADI implementations are not created solely with existing filter values, although this, too, is possible.

    2. Multiple-Use

    3. Filter-Dependent

    Instance Methods can access all of the attributes of a class and can trigger all events of a class. Static Methods can only access static attributes and static events.

    Exceptions:

    Events:

    Events can be defined in classes or in interfaces. Corresponding methods can trigger these events with the RAISE EVENT statement. Each class (or interface) that is going to handle the corresponding event must implement a relevant handler method, and register it using the SET HANDLER statement. When an event occurs, the system calls all of the handler methods registered for that event.

    Like method definitions, events have a parameter interface. The only difference is that events may only have EXPORTING parameters.

    BADI : Businees Add IN's

    Business Add-Ins are SAP enhancement technique based on ABAP Objects.

    Where the SAP standard program is not going to fullfill the client requirement , we are going to add our own program to SAP standard program, without changing the standard prog.

    Each Business Add-In has

    – at least one Business Add-In definition

    – a Business Add-In interface

    – a Business Add-In class that implements the interface

    Each BADI has two different Views.

    1.Definition view

    2.Implementation view

    T.C for BADI Definition is SE18.

    T.C for BADI Implementation is SE19.

    There are multiple ways of searching for BADI.

    • Finding BADI Using CL_EXITHANDLER=>GET_INSTANCE

    • Finding BADI Using SQL Trace (TCODE-ST05).

    • Finding BADI Using Repository Information System (TCODE- SE84).

    1. Go to the Transaction, for which we want to find the BADI, take the example of Transaction VD02. Click on System->Status. Double click on the program name. Once inside the program search for ‘CL_EXITHANDLER=>GET_INSTANCE’.

    Make sure the radio button “In main program” is checked. A list of all the programs with call to the BADI’s will be listed.

    The export parameter ‘EXIT_NAME’ for the method GET_INSTANCE of class CL_EXITHANDLER will have the user exit assigned to it. The changing parameter ‘INSTANCE’ will have the interface assigned to it. Double click on the method to enter the source code.Definition of Instance would give you the Interface name.

    2. Start transaction ST05 (Performance Analysis).

    Set flag field "Buffer trace"

    Remark: We need to trace also the buffer calls, because BADI database tables are buffered. (Especially view V_EXT_IMP and V_EXT_ACT)

    Push the button "Activate Trace". Start transaction VA02 in a new GUI session. Go back to the Performance trace session.

    Push the button "Deactivate Trace".

    Push the button "Display Trace".

    The popup screen "Set Restrictions for Displaying Trace" appears.

    Now, filter the trace on Objects:

    • V_EXT_IMP

    • V_EXT_ACT

    Push button "Multiple selections" button behind field Objects

    Fill: V_EXT_IMP and V_EXT_ACT

    All the interface class names of view V_EXT_IMP start with IF_EX_. This is the standard SAP prefix for BADI class interfaces. The BADI name is after the IF_EX_.

    So the BADI name of IF_EX_CUSTOMER_ADD_DATA is CUSTOMER_ADD_DATA

    3. Go to “Maintain Transaction” (TCODE- SE93).

    Enter the Transaction VD02 for which you want to find BADI.

    Click on the Display push buttons.

    Get the Package Name. (Package VS in this case)

    Go to TCode: SE84->Enhancements->Business Add-inns->Definition

    Enter the Package Name and Execute.

    Here you get a list of all the Enhancement BADI’s for the given package MB.
