I need to use this code, but It does not work in PAI. I want to disable a numc field when I push a button in PAI but it makes me nothing.

loop at screen.

if screen-name = ''.

screen-input = 0.

endif.

modify screen.

endloop.

What I should do?

thanks.

Write your code in PBO.

loop at screen.

if screen-name = '<name of the field you want to disable>'.

screen-input = 0.

modify screen.

endif.

endloop.

Hi,

Are you passing screen-name = 'screenstructure-fieldname'

to this?.

and write this logic at PBO event.

<b>then change code like below:</b>

Loop at screen.

if screen-name = 'AUX'.

screen-input = 0.

modify screen.

endif.

Endloop.

<b>whenever an event is fired from PAI , the execution of the code control goes from PAI to PBO. so if you put the code in PBO , this code will execute when screen re-displayed . if you put in PAI , first object will be disabled , if you press 'ENTER' then again it will enabled.</b>

Hi,

Instead of screen-name = ' ' try using the field name of numc field you want to disable.

Cheers,

Ensure the field name is all caps.

screen-name = 'FIELDNAME'.

It is a field whose name is 'aux'. It does not have structure associated.

As suggested by Ravi put your logic in PBO module

loop at screen.

if screen-name = 'AUX'.

screen-input = 0.

modify screen.

endif.

endloop.

You might want to read the documentation about how the screen elements work before coding.

Hi,

You need to do it in PBO because this is the event that occurs prior to displaying the screen. When you set screen-input = 0 in the PAI, the values are taken from the screen layout definition for the field causing the screen-input to be set to 1. You can override this during PBO. One way to "connect" your PAI 'SAVE' function to the PBO "loop at screen" is to use a flag variable.

Example:

PBO module

  
  IF my_flag = 'X'.
    LOOP AT SCREEN.
      IF screen-name = 'AUX'.
        screen-input = 0.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
  ENDIF.

PAI module:


...
  when 'SAVE'.
    if my_flag is initial.
      my_flag = 'X'.
    endif.
