Hi
Every BADI by default Implements an INTERFACE which already contains some methods with parameters.
So you have to find the relavenet method based on the related paramters (by checking the fields in that paramters) you have to double click on the method and to write the code.
see the doc
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
😎 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.

Hi Praveen,
First create a instance of a class in your badi.
You can press the pattern button in the badi and then click the ABAP objects radiobutton.give the name of the instance,class and method after that press enter.
Your class will be called.

Hi,
Implementing Business Add-Ins (BADI)
The use of object orientated code within SAP has lead to new method of enhancing standard SAP code called
Business Add-Ins or BADI's for short. Although the implementation concept is based on classes, methods and
inheritance you do not really have to understand this fully to implement a BADI. Simply think of methods
as a function module with the same import and export parameters and follow the simple instructions below.
Steps:
1. Execute Business Add-In(BADI) transaction SE18
2. Enter BADI name i.e. HRPBSGB_HESA_NISR and press the display
button
3. Select menu option Implementation->Create
4. Give implementation a name such as Z_HRPBSGB_HESA_NISR
5. You can now make any changes you require to the BADI within this
implementation, for example choose the Interface tab
6. Double click on the method you want to change, you can now enter
any code you require.
7. Please note to find out what import and export parameters a
method has got return the original BADI definition
(i.e. HRPBSGB_HESA_NISR) and double click on the method name
for example within HRPBSGB_HESA_NISR contract is a method
8. When changes have been made activate the implementation
