Question on BADI

Hello ABAPers

Just wanted to know a few things on a BADI.

1) In BADI what is the difference between a Definition and Implementation ?

2) Lets take a BADI <i>COM_PARTNER_BADI</i> for partner processing in CRM.

If you go into the details of this BADI, and take three methods namely, DETERMINATION_ADD_IN_1

DETERMINATION_ADD_IN_2

DETERMINATION_ADD_IN_3

Are theses methods alredy coded ? I mean have they been implemented already by SAP ?

3) If yes, what is the enhancement the customer is making ?

4) If anybody could explain these in relation to java, it may be more useful to me as I have java knowledge.

Eagerly awaiting for a response

Jessy

    Hi Jessy,

    BADI is similar to user exit which we use in the previous versions.

    Since ABAP is being made Object orientated, we use the concept of BADI then user exits.

    1) You need to create a implementation first. This is done using transcttion SE19.

    Give the standard BADI name and press create. give a Z or Y name for your implementation.

    Once this is done, use the name which you have given above in EDIT implementation of SE19 screen.

    you can see many method names in this implementation. double click on the method which you want and write the logic.

    2) Those methods are not already coded.

    3) There may be situation wher customer needs to modidy some standard logic.

    for example, let say the customer needs the PO NUMBER field in Sales order in UPPER CASE always. even if the user enters combination, we must convert it to upper case.

    In the above senario, we go for these BADI implementtion. You can check for same methods like change_sales_header (Not exaclty) and write the code here.

    This method will be called automatiically and hence the field will be converted to Uppercase.

    4) Well, in terms of JAVA, i can say that, these methods are like methods defined in interfaces. for example, you implement a EVENT class. so in your program, you write methods/ codes to handle the various types of events like click, double click etc.... These methods (click, double click etc...) are predefined in JAVA. you need to write just the code.

    Hope you understand. Reward points if usefull..

    Regards,

    Niyaz

    Hi,

    1) In BADI what is the difference between a Definition and Implementation ?

    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.

    Thanks.

    Hi

    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.
