Hide/Show parameter based on another parameter

[Former Member]

Hi All,

Is there a way to hide the parameters initially on the screen and only showing them when another field is selected?

For example, when I click on "range" then I want to to display two fields....start date and end date.

Thanks,

~Mark

Hi Mark

In the selection screen

you can use the code

AT SELECTION-SCREEN OUTPUT.

IF pa_equip <> 'X'.
LOOP AT SCREEN.
IF screen-group1 = 'I1'.
screen-active = 0.
MODIFY SCREEN.
ENDIF.
ENDLOOP.
ENDIF.

IF pa_logic <> 'X'.
LOOP AT SCREEN.
IF screen-group1 = 'I2'.
screen-active = 0.
MODIFY SCREEN.
ENDIF.
ENDLOOP.
ENDIF.

You will get many examples if you search the forum.

Hi Mark

If the click you are referring to is on a check box or radio button, yes we can do it. But if selection are to be invoked when you click on label, i think it may not be possible.

An example on a possible scenario is:

parameters: p_rd1 radiobutton group rad1 default 'X' user-command but,
            p_rd2 radiobutton group rad1,
            p_text type char128 obligatory.

at selection-screen output.

  loop at screen.
     if screen-name CP '*P_TEXT*'.
        if not p_rd1 is initial.
           screen-active = 1.
           screen-required = 1.
        else.
           screen-active = 0.
           screen-required = 0.
        endif.
        modify screen.
     endif.
  endloop.

Thanks for your reply Eswar.

This code will hide the entire screen and not the specific fields? How do I hide just the fields?

Mark in my example above am doing the manipulations only to parameter P_TEXT.

Check another example:

PARAMETERS: p_chb AS CHECKBOX USER-COMMAND chb,
            p_file TYPE localfile.

AT SELECTION-SCREEN OUTPUT.

  LOOP AT SCREEN.
    IF screen-name CP '*P_FILE*'.
      IF p_chb IS INITIAL.
        screen-active = 0.
      ELSE.
        screen-active = 1.
      ENDIF.
      MODIFY SCREEN.
    ENDIF.
  ENDLOOP.

To have a better feel, execute in a temporary program.

Thanks I got it. I missed online.

So initially when the checkbox is not checked the other field does not appear, then when I make it checked can I make the field appear dynamically?
