    Hi,

    IMPLEMENTATION OF BADI DEFINITION

    1) EXECUTE tcode se18.choose menuitem create from the implementation menubar.

    2) Specify aname for implementation ZIM_LINESEL

    3) Specify short desc.

    4) Choose interface tab. System proposes a name fo the implementation class.

    ZCL_IM_IMLINESEL which is already generarted.

    5) Specify short desc for method

    6) Dbl clk on method to insert code.

    7) Save , check and activate the code.

    Regards,

    Satish

    Business Add-Ins

    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 (SMOD/CMOD Page 40), 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-system infrastructure (SAP and customers), but instead allow for multiple levels of software development (by SAP, partners, and customers, and 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. In Release 4.6A, program and menu enhancements can be made with Business Add-Ins. 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

    DEFINING THE BADI

    1) execute Tcode SE18.

    2) Specify a definition Name : ZBADI_SPFLI

    3) Press create

    4) Choose the attribute tab. Specify short desc for badi.. and specify the type :

    multiple use.

    5) Choose the interface tab

    6) Specify interface name: ZIF_EX_BADI_SPFLI and save.

    7) Dbl clk on interface name to start class builder . specify a method name (name,

    level, desc).

    Method level desc

    Linese;ection instance methos some desc

    8) place the cursor on the method name desc its parameters to define the interface.

    Parameter type refe field desc

    I_carrid import spfli-carrid some

    I_connid import spefi-connid some

    9) save , check and activate…adapter class proposed by system is

    ZCL_IM_IM_LINESEL is genereated.

    IMPLEMENTATION OF BADI DEFINITION

    1) EXECUTE tcode se18.choose menuitem create from the implementation menubar.

    2) Specify aname for implementation ZIM_LINESEL

    3) Specify short desc.

    4) Choose interface tab. System proposes a name fo the implementation class.

    ZCL_IM_IMLINESEL which is already generarted.

    5) Specify short desc for method

    6) Dbl clk on method to insert code..(check the code in “AAA”).

    7) Save , check and activate the code.

    Now write a sample program to use this badi method..

    Look for “BBB” sample program.

    “AAA”

    data : wa_flights type sflight,

    it_flights type table of sflight.

    format color col_heading.

    write:/ 'Flight info of:', i_carrid, i_connid.

    format color col_normal.

    select * from sflight

    into corresponding fields of table it_flights

    where carrid = i_carrid

    and connid = i_connid.

    loop at it_flights into wa_flights.

    write:/ wa_flights-fldate,

    wa_flights-planetype,

    wa_flights-price currency wa_flights-currency,

    wa_flights-seatsmax,

    wa_flights-seatsocc.

    endloop.

    “BBB”

    &----


    *& Report ZBADI_TEST *

    *& *

    &----


    REPORT ZBADI_TEST .

    tables: spfli.

    data: wa_spfli type spfli,

    it_spfli type table of spfli with key carrid connid.

    *Initialise the object of the interface.

    data: exit_ref type ref to ZCL_IM_IM_LINESEL,

    exit_ref1 type ref to ZIF_EX_BADISPFLI1.

    selection-screen begin of block b1.

    select-options: s_carr for spfli-carrid.

    selection-screen end of block b1.

    start-of-selection.

    select * from spfli into corresponding fields of table it_spfli

    where carrid in s_carr.

    end-of-selection.

    loop at it_spfli into wa_spfli.

    write:/ wa_spfli-carrid,

    wa_spfli-connid,

    wa_spfli-cityfrom,

    wa_spfli-deptime,

    wa_spfli-arrtime.

    hide: wa_spfli-carrid, wa_spfli-connid.

    endloop.

    at line-selection.

    check not wa_spfli-carrid is initial.

    create object exit_ref.

    exit_ref1 = exit_ref.

    call method exit_ref1->lineselection

    EXPORTING

    i_carrid = wa_spfli-carrid

    i_connid = wa_spfli-connid.

    clear wa_spfli.

    There are two steps in User Exit / BADI creation.

    1} Identify the User Exit suitable for the requirement and that is available in the system:

    Code SE18 is used to Identify the BADI available.

    Look for the string 'CL_EXITHANDLER' in the standard program. This is a class which has a method 'GET_INSTANCE' which is used to trigger BADI's from the Standard Program. The interface parameter for this static method 'EXIT_NAME' is used to pass the BADI to the method.

    Open Standard Program and do a global search 'CL_EXITHANDLER'.

    SE18 > give the BADI name found through above search.

    CUSTOMER_ADD_DATA > which has a method SAVE_DATA.

    2} Implement the User Exit identified through above process.

    T.Code SE19 is used to Implement BADI.

    SE19 > give the implementation name > Give the Definition name as CUSTOMER_ADD_DATA and the Short Text.

    Reward points if useful.
