Capture Fcode at selection screen.

[Former Member]

hello all,

here is my problem,

i have created a report in which on one parameter i have created custom F4 Help.

code snippet:

SELECTION-SCREEN: BEGIN OF BLOCK B1.
PARAMETERS: P_EXNUM TYPE J_1IEXCHDR-EXNUM  OBLIGATORY.
SELECTION-SCREEN: END  OF BLOCK   B1.

at this parameter p_Exnum F4 help is been assigned.

"most importantly i wanted to restrict the selection so i created a

"selection screen with few parameters & select-options on it.

"selection screen is been called as a pop up window.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_EXNUM.
  CALL SELECTION-SCREEN 100 STARTING AT 004 006 ENDING AT 85 014.
  BREAK PPUSER.
  IF S_WERKS[] IS INITIAL AND S_MATNR[] IS INITIAL AND
    S_KUNAG[] IS INITIAL AND S_KUNWE[] IS INITIAL AND
    P_BUDAT[] IS INITIAL AND P_EXYEAR[] IS INITIAL.
    MESSAGE 'Enter Help Parameters' TYPE 'S' DISPLAY LIKE 'E'.
    RETURN.
  ENDIF.

this is how i created the selection-screen:

SELECTION-SCREEN: BEGIN OF SCREEN 100 TITLE TEXT-004.
 SELECT-OPTIONS : S_WERKS FOR J_1IEXCHDR-WERKS,
 S_MATNR FOR J_1IEXCDTL-MATNR,
 P_BUDAT FOR J_1IEXCHDR-EXDAT.
 SELECTION-SCREEN: END OF SCREEN 100 .

what i want:

there are few buttons on selection screen. like execute, cancel(cross button), check, save(varient save buttuon).

the problem is after filling pop up selection screen, when i press execute, i debugging, sy-ucomm is empty.

i want to capture the F-Code of the buttons on selection screen and wanted to code accordingly.

say:

if user press execute : and if all selection screen parameters are initial.
"throw error msg.
endif.

plz suggest how the achieve the same.

You will get the value of Function code (SY-UCOMM) in the event AT SELECTION-SCREEN, where you are supposed to do the validation.  Since you are using two selection screens, you have to check the screen number (SY-DYNNR) for carrying out appropriate validation according to the screen.

By default if you call it with CALL SELECTION SCREEN, only foru buttons gets displayed like "execute" , "variant", "Check syntax", "cancel". Try to create a function module which internally calls the selection screen, it will be better.Create separate includes for selection screen declaration and selection screen events.

After the call just check sy-subrc = 0 , then its execute button clicked.

at selection-screen on value-request for p_exnum.

  call function 'CALL_F4'

       importing

         result = it_result.

Function CALL_F4.

CALL SELECTION-SCREEN 100 STARTING AT 004 006 ENDING AT 85 014.

if sy-subrc <> 0.

MESSAGE i112 RAISING cancelled.

else.

....................................

endif.

endfunction

Kesav,

If I am not mistaken, OP want to capture the function code selected in the selection screen(popup) which is called from ON-VALUE request event.  I think, that is possible only from the event AT SELECTION-SCREEN.

For example, if save button is selected then SY-UCOMM will hold the value 'SPOS'.

AT SELECTION-SCREEN.
   IF sy-dynnr = '0100'.   "Selection screen in popup"
      IF sy-ucomm = 'CRET'   "Execute Button"
         ..... validations.
      ENDIF.
   ENDIF.

Vinod,

You got it correct and I got it wrong ...

[Aashish28]

Hiii,

         Just put break point AT SELECTION-SCREEN. than check sy-ucomm and sy-dynnr value you will find value

CRET - Execute

NONE - Check

SPOS - Save

thats my reply to all of u.

infact its a question.

at selection-screen on value request for p_exnum.

after pressing F4 at paramter p_exnum , only the entire code in above event is calling.

as soon as system detects the end of code in the event :

at selection-screen on value request for p_exnum.

Control flow exits i.e. comes back to initial selection-screen of Report.

in short Event At selection screen is not getting triggered!

and i guess u all are saying to capture the F- Codes at this event.

for the convenience i am posting my entire code just before the event START-OF-SELECTION.

Take a look. (Actually this report finally calls a Smartform).

"This is from where control flow exits.

i stronly want to these F-Codes at this event.

the code which is to be written is for this event only(F4 Help).

to be honest i am also in dilemma that why AT SELECTION SCREEN IS is not getting triggered?

[kesavadas_thekkillath]

AT SELECTION-SCREEN." while pressing F4 this event is not getting triggered"

It will not trigger on F4, it will trigger on "Execute" or "Enter".

[Aashish28]

Hiii,

AT SELECTION-SCREEN." while pressing F4 this event is not getting triggered : - Yes when you press execute or enter - at selection-screen will trigger .otherwise write code on -

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_EXNUM.

Just Try this -

TABLES :J_1IEXCHDR,mara.


     SELECTION-SCREEN: BEGIN OF BLOCK B1.

     PARAMETERS: P_EXNUM TYPE J_1IEXCHDR-EXNUM  OBLIGATORY.

     SELECTION-SCREEN: END  OF BLOCK   B1.


     SELECTION-SCREEN: BEGIN OF SCREEN 100 TITLE TEXT-004.

     SELECT-OPTIONS : S_WERKS FOR J_1IEXCHDR-WERKS,

     S_MATNR FOR mara-MATNR,

     P_BUDAT FOR J_1IEXCHDR-EXDAT.

     SELECTION-SCREEN: END OF SCREEN 100 .

     AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_EXNUM.

      CALL SELECTION-SCREEN 100 STARTING AT 004 006 ENDING AT 85 014.
     AT SELECTION-SCREEN.

       if sy-ucomm = 'CRET'.

       IF S_WERKS[] IS INITIAL AND S_MATNR[] IS INITIAL.

*        S_KUNAG[] IS INITIAL AND S_KUNWE[] IS INITIAL AND
*
*        P_BUDAT[] IS INITIAL AND P_EXYEAR[] IS INITIAL.

         MESSAGE 'Enter Help Parameters' TYPE 'E' .

         RETURN.

       ENDIF.

       elseif sy-ucomm = 'ONLI' .

          MESSAGE 'First Screen message' TYPE 'E' . " Write your logic here
      

      else.

          MESSAGE 'First Screen message' TYPE 'E' . " Write your logic here       

       endif.

Yes, Kesav is right.  AT-SELECTION screen will be executed only if you select the function codes CRET (Execute) & NONE (Check) in the selection screen (POPUP).  Ideally, your validations should be in AT-SELECTION SCREEN, as there any many restrictions/limitations in using MESSAGE statement in event POV.  http://help.sap.com/abapdocu_731/en/abenabap_message_dialog.htm

Only when user select close button on selection-screen (POPUP), AT-SELECTION screen event will not be triggered. For this scenario, you may have to do appropriate validations in AT SELECTION-SCREEN event of default selection screen.

Dear,

Please give fcode to screen PB and in screen user command save it to variable and use it to your selection screen validation part if needed use import export.
