BAdI error : type of EXIT_REF1 cannot be converted to the type of EXIT_REF

[Former Member]

Hi all,

The below was the posted earlier for BAdI. Ihave followed all the steps. And i have written the below code. Syntactically it is not showing any errors, but when i am activating i am getting error

like " The type of EXIT_REF1 cannot be converted to the type of EXIT_REF". where i am doing the mistake..??

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.

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. "" The type of EXIT_REF1 cannot be converted to the type of EXIT_REF"

call method exit_ref1->lineselection

EXPORTING

i_carrid = wa_spfli-carrid

i_connid = wa_spfli-connid.

clear wa_spfli.

Thanks in advance

You are trying to assign a class instance (object) to an interface reference variable.

Just create an interface reference and use this reference variable to get the instance of the BADI.

DATA: lf_var TYPE REF TO IF_XXXX.

call method cl_exithandler =>get_instance

EXPORTING

exit_name = <badi name>

CHANGING

instance = lf_var

Call method if_var -> <methd name>

Exporting

Changing

Hello

Assuming that exit_ref (ZCL_IM_IM_LINESEL) implements interface IF_EX_BADISPFLI1 then the following coding might work:

data: exit_ref type ref to ZCL_IM_IM_LINESEL,
"exit_ref1 type ref to ZIF_EX_BADISPFLI1.
lo_intf     TYPE REF TO if_ex_badispfli1.

...
at line-selection.
check not wa_spfli-carrid is initial.
create object exit_ref.
lo_intf ?= exit_ref.
