screen-input?

[Former Member]

Hi, Guru:

I have a question on SCREEN-INPUT. In the PAI, I set one field SCREEN-INPUT to 0. but once click one button. In the PBO, Its value automatically always change to 1.

Is there any place to setup, I want to write code to change it.

Thanks in advance !

You must always set the screen attributes in the PBO, not the PAI.

Hi,

You have to use <b>MODIFY SCREEN</b> statement, whenever you change any atrribute of screen field.

So it is like.

LOOP AT SCREEN.
   IF SCREEN-NAME = 'XYZ'.
      SCREEN-INPUT  = '1'.
   ENDIF.
   MODIFY SCREEN.
ENDLOOP.

Let me know if you still have a issue.

Hi, RS:

Thanks for your help, actullay I want to toggle for this field. but it always disable

when it display on the screen. my code as the following:

loop at screen.

• if screen-group1 = 'GR1'.

if screen-name = 'V_CURRENT_TERM-FACILITY_NAME'.

if screen-input = 0.

screen-input = 1.

elseif screen-input = 1.

screen-input = 0.

endif.

modify screen.

endif.

endloop.

If the field has been statically defined in screen painter as an input field, then it will have this value everytime the PBO is fired. So you need only to change the INPUT value when required.

Hi, Rich:

my field is input field. but when I debug it.

SCREEN-REQUIRED = 0. Is that ok or I should set SCREEN-REQUIRED to 1.

Thank you again.

[RichHeilman]

The REQUIRED field is simply to make it obligatory, but doing this is a little buggy. If you turn this off, you will not be able to turn it off without a value being entered. This will not help your requirement.

You requirement is to simply turn a field on/off depending on a click off a button, example... change/display right?

Hi, RIch Heilman:

You are right. I just make a field enable or disable when click a button.

It's simple. but It's not working. I really don't know what happened.

thank you for your help.

[RichHeilman]

If this is your requirement, here is how to proceed. Create a simply flag variable in your TOP include or at the top of the program

data:  toggle type c.

Now in your PAI, for the specific button or icon, you will want to toggle the value of this field.

case sy-ucomm.
    when 'CHG'.
        toggle = 'X'.
    when 'DSP'.
        toggle = space.
endcase.

Then in your PBO, you will want to check this value and make the feild input or output accordingly.

Loop at screen.
   if screen-name = 'YOUR_FIELD'
      and toggle = space.
      screen-input = 0.
      modify screen.
  endif.
endloop.
