Why is this small code giving me error? Dynpro (screen programming ques)

Former Member — Mon, 17 Dec 2007 21:44:40 GMT

Hello all,

I wrote this code for dynpro and there is an error .. Could you please see this and tell me where is it?

Code::

REPORT z_sm_test_dynpro .

DATA sy_ucomm_1 TYPE sy-ucomm.

DATA ok_code_1 type ok_code.

DATA ok_code_2 type ok_code.

*call the screen you want

CALL SCREEN 2000.

*event PBO starts

process before output.

*module for holding code of PBO

MODULE status_2000 OUTPUT.

Gui status is set: For details doubleclick 'STATUS_1'

SET PF-STATUS 'STATUS_1'.

*set the titlebar

SET TITLEBAR '100'.

*that is all for PBO

ENDMODULE.

*optional to tell this event below

PAI event starts.

process after input.

*module for holding code of PAI

MODULE user_command_2000.

ok_code_1 = ok_code.

*Question: why clear it?

CLEAR ok_code.

*do things based on input

CASE ok_code_1.

when 'BACK' or 'EXIT' or 'CANCEL'.

leave program.

when others.

output = save_ok.

endcase.

*thats all for PAI

ENDMODULE.

Thanks,

Charles.

Well, it would sure help if you would tell us the error.

OK - I think I see. You have to put the PAI and the PBO statments in the screen, not the report. If you just double click on the screen number, you will be able to do this.

Hi,

the only error I found is this...

the type OK_CODE does not exist in your program. you will need to declare OK_CODE in the screen first.

use the following declaration in ur program

data: ok_code_1 type sy-ucomm,

ok_code type sy-ucomm.

in PAI.

ok_code_1 = ok_code.

case ok_code_1.

endcase.

Note: OK_CODE should be declared inthe screen element list.

It would be more clear if you could mail the details of the error.

Regards,

Vamsi.

copy and paste the fo.. code in se38.

DATA sy_ucomm_1 TYPE sy-ucomm.

DATA ok_code_1 type ok_code.

DATA ok_code_2 type ok_code.

*call the screen you want

CALL SCREEN 2000.

*event PBO starts

*process before output.

*module for holding code of PBO

MODULE status_2000 OUTPUT.

*Gui status is set: For details doubleclick 'STATUS_1'

SET PF-STATUS 'STATUS_1'.

*set the titlebar

SET TITLEBAR '100'.

*that is all for PBO

ENDMODULE.

*optional to tell this event below

*PAI event starts.

*process after input.

*module for holding code of PAI

MODULE user_command_2000.

ok_code_1 = sy-ucomm.

*Question: why clear it?

*CLEAR ok_code.

*do things based on input

CASE ok_code_1.

when 'BACK' or 'EXIT' or 'CANCEL'.

leave program.

when others.

*output = save_ok.

endcase.

after this double click on screen 2000. and uncomment modules, active it.

and again come back to se38 and double click on pf_status, set req. tools there and activate it.

hi,

do this..

DATA sy_ucomm_1 TYPE sy-ucomm.

DATA ok_code_1 type sy-ucomm.

DATA ok_code_2 type sy-ucomm.

u get error because ok_code is not an abap dictionary type..

Hello all,

I have this ques.. Kamini above said that the element OK_code is not a data dictionary type so you cannot define variable of this type. But it is an element in the dictionary, so it should work.. eg MATNR is an element but still the code below works:

*code::

REPORT z_test1.

DATA a type MATNR.

a = '2242'.

WRITE: 'a holds', a.

Thanks,

Charles.

Hi Charles,

Here u r declaring A type matnr.

Matnr is a data element which is type CHAR with length 18.

so ur code is same as A type C.and ur moving 2242 into A.

after that u r printing.

I think u got my point.

Hello Charles

The flow logic of a standard screen looks like:


PROCESS BEFORE OUTPUT.
  MODULE STATUS_0100.
*
PROCESS AFTER INPUT.
  MODULE USER_COMMAND_0100.

The modules can be coded within your report again.

A typical USER_COMMAND module looks like:


  TRANSLATE gd_okcode TO UPPER CASE.


  go_grid->check_changed_data( ).

  CASE gd_okcode.
    WHEN 'BACK' OR
         'END'  OR
         'CANC'.
      SET SCREEN 0. LEAVE SCREEN.



    WHEN OTHERS.
  ENDCASE.


  PERFORM handle_changed_data.
  PERFORM validate_output.
  CALL METHOD go_grid->refresh_table_display
*      EXPORTING
*        IS_STABLE      =
*        I_SOFT_REFRESH =
    EXCEPTIONS
      finished       = 1
      OTHERS         = 2
          .
  IF sy-subrc <> 0.
*     MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*                WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.


  CLEAR: gd_okcode.  " Define as TYPE sy-ucomm (I prefer TYPE ui_func).

At the end of the USER_COMMAND module we always clear the ok_code because we do not want to have a preset ok_code at the next display of the screen.

Uwe

Hello,

Uwe, you are using gd_okcode and I used OK_CODE but the question is how do I define/declare this variable and where? If the right way is DATA ok_code TYPE sy-ucomm. then how will SAP know that this is the variable to be populated with the Function code from the screen?

One more thing.. Can we paste any screenshot in the posts here (eg to illustrate a question or answer)

Thanks,

Charles.

Hi,

Use this way

data : gd_okcode like sy-ucomm. "<<<<<<<<

gd_okcode = sy-ucomm. "<<<<<<<<

CASE gd_okcode.

WHEN 'BACK' OR

'END' OR

'CANC'.

SET SCREEN 0. LEAVE SCREEN.

WHEN OTHERS.

ENDCASE.
