BADI's

[Former Member]

I'm new to ABAP. Can any one help me out in knowing me--

1. what is BADI

2.How to start it and why do we use it.

3. Steps included in BADI

Hi

BADI can be used for multiple implementations

that is the difference between user exit and Badi.

which-ever thing you execute that related code will be executed.

see the Badi's doc

<b>Business Add-Ins</b>

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

Line selection instance methods some description

😎 place the cursor on the method name description 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.

BAdI 1

This BAdI is only required if the BAPI has an ExtensionIn parameter. This BAdI allows the customer to check all the data that is passed on to the BAPI, including the ExtensionIn parameter. The BAdI must have the following parameters:

All BAPI import parameters and tables are passed on as an import. In particular, the ExtensionIn parameter must be available in the BAdI.

The BAdI must return the Return parameter as an export, to allow the BAPI to report any errors that occurred in the BAdI.

If required by the application, additional parameters can also be passed on to the BAdI as import or export.

Business Add-Ins (BAdIs)

Each BAPI function module must contain a maximum of two extra BAdIs in addition to the exits provided by the application. The first BAdI must enable customers to check all the data that is transferred to the BAPI. In particular, the content of the ExtensionIn parameter should be checked before its contents are processed further in the BAPI. The second BAdI is provided whenever the customer is allowed to perform additional processing activities (such as writing to additional tables, reading additional values, or selecting data by additional criteria). If the customer has enhanced the export parameter of the BAPI, the second BAdI should be used to fill the ExtensionOut parameter.

Please reward if useful.

HI Shori,

Regarding BADI I have a query. In your previous reply, u mentioned that ' If required by the application, additional parameters can also be passed on to the BAdI as import or export'. Could you please tell me the way to do this.

I want to pass some additional parameters to BADI. How can I do this?

Whether it is possible or not?

Many thanks in Advance.
