                  sl_kunnr for a602-kunnr,
                  sl_vtweg for a950-vtweg,
                  sl_datab for a602-datab no intervals no-extension.

Hi,

Try this.

LOOP AT SCREEN.

IF screen-name = 'SL_VTWEG-LOW' OR screen-name = 'SL_VTWEG-HIGH'.

IF SL_KUNNR IS NOT INITAIL.

SCREEN-INPUT = 1.

ELSE.

SCREEN-INPUT=0.

ENDIF.

MODIFY SCREEN,

ENDLOOP.

Give "sl_vtweg for a950-vtweg" a MODIF ID

Eg. sl_vtweg for a950-vtweg MODIF ID B1.

Then you can do:

loop at screen.
  if screen-group1 eq 'B1'.
    screen-invisible = 1.
  endif.
 modify screen.
endloop.

Hello kostonstyle,

Rewrite your code as below to avoid syntax error.

loop at screen.

if screen-name = '%_SL_VTWEG_%_APP_%-TEXT'.

screen-visible = 0.

modify screen.

endif.

endloop.

Writing this statement in the event at selection screen on sl_kunnr will not meet your requirement as this event is triggered only when you execute the report.

You need to assign a user-command to sl_kunnr. See F1 for help.

Then write the above code in at selection-screen output event.

/spoonfeed

AT SELECTION_SCREEN OUTPUT.

IF NOT sl_kunnr[] is initial.

* Do your stuff

ENDIF.

I'm sure there are other ways, but honestly i cba to look them up.

Try it this way:

select-options:   sl_matnr for mara-matnr obligatory,
                  sl_vkorg for a950-vkorg," obligatory no intervals no-extension,
                  sl_kunnr for a950-kunnr,
                  sl_vtweg for a950-vtweg,
                  sl_datab for a950-datab no intervals no-extension.



at selection-screen output.

 if sl_matnr[] is not initial.
  loop at screen.
    if screen-name CS 'SL_VKORG'.
       SCREEN-ACTIVE = 0.

       MODIFY SCREEN.

    endif.
  endloop.
endif.

With luck,

Pritam.

You cannot change the screen in the AT SELECTION-SCREEN ON.. event. You have to do it in AT SELECTION-SCREEN OUTPUT. Also, to trigger AT SELECTION-SCREEN OUTPUT, the user has to press enter after a value is entered in the selection screen. You can try something like this.



DATA: kunnr_entered TYPE c.

select-options:   sl_matnr for mara-matnr obligatory,
                  sl_vkorg for a602-vkorg obligatory no intervals no-extension,
                  sl_kunnr for a602-kunnr,
                  sl_vtweg for a950-vtweg,
                  sl_datab for a602-datab no intervals no-extension.

AT SELECTION-SCREEN ON sl_kunnr.
  IF sl_kunnr IS NOT INITIAL.
    kunnr_entered = 'X'.
  ELSE.
    CLEAR kunnr_entered.
  ENDIF.

AT SELECTION-SCREEN OUTPUT.
  IF kunnr_entered = 'X'.
    LOOP AT SCREEN.
      CHECK screen-group1 = 'KUN'.
      screen-active = 0.
      MODIFY SCREEN.
*-- even if the value is entered, clear it
      CLEAR sl_vtweg[].
    ENDLOOP.
  ELSE.
    LOOP AT SCREEN.
      CHECK screen-group1 = 'KUN'.
      screen-active = 1.
      MODIFY SCREEN.
    ENDLOOP.
  ENDIF.

CHECK screen-group1 = 'KUN'.

You forgot to add the MODIF ID KUN.

and this code

AT SELECTION-SCREEN ON sl_kunnr.
  IF sl_kunnr IS NOT INITIAL.
    kunnr_entered = 'X'.
  ELSE.
    CLEAR kunnr_entered.
  ENDIF.

is just waste of time, because the content of sl_kunnr can be checked in the PBO directly. Anyway, it was worth 6 points...

Re: Dynamic Selection Screen

It's a selection screen. Given the requirements, how do you want to check the contents of the select-option in the PBO and act upon them?

But i agree, it's a bit silly to set an indicator that the select-option is filled.

edit: on second thought, perhaps you meant the SELECTION_SCREEN OUTPUT when you wrote PBO.

there are no tricks needed, it is possible to do it directly, just have a look at my solution above and give it a try! (of course the PBO has to be triggered through a USER-COMMAND, but it is necessary in any case)

Aahh that post!

While i was posting my first reply, you already hit submit. Hence my reply was a minute later.

And trust me, with 13 years of experience i don't think i need to try it out.

yes!

by simple report programming:

AT SELECT-SCREEN OUTPUT - this is PBO for the (automatically generated) selection screen

AT SELECTION-SCREEN ON ... - these are PAIs for the (automatically generated) selection screen

but I believe this is clear-cut for you with 13 years of experience
