Defining a form in a BADI method ???

Former Member

Hi everyone,

There is a possibility to define a form and call it in a method of an BADI interface ?

Thanks & regards

Hello Hassan

Although you obviously have found a possibility to call a routine within a method this is not ABAP-OO like.

Assuming that the routine is <i>custom-defined</i> (not a routine in a SAP standard program) then you should simply place the coding (of the routine) into a <b>private method</b> of the class which implements the BAdI.

Regards

Uwe

Hi,

If you are asking about creating routines like below

FORM subroutine_test.

ENDFORM.

and want to use PERFORM in a badi implementation its not possilbe.

Since BADI implementaiton is nothing but a global class and in a global class you cannot create local subroutines and use PERFORM to call them.

But you can use PERFORM to call routines of a different program.

Like this PERFORM routine_name IN <program_name>.

I have found the solution :

You can put the FORM routine in a subroutine pool(a separate program) and then call it within your METHOD like this.

perform some_form in program ZSUB_POOL.

You can create this subroutine pool using SE38, and selecting the appropriate program type.

Hi,

YES you are right as I have given in my first post.

We cannot create local routines but we can call routines from any other program (Which can be in a subrotuine pool, or function pool or module pool).

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

Also do refer,

http://sap.ittoolbox.com/groups/technical-functional/sap-dev/custom-badi-implementation-324215

We can have multiple implementations for BADI

that property of BADI makes it different from user exits

see the BADI 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,

The solution :

perform sub_routine in program program_name

don't work for forms that have parameters using/changing !!!

There is a solution to call forms with they parameters?

Thanks & regards
