You need to add the below code in one of the userexit so as that it trigger accordingly.

if sy-tcode = <display>.

loop at screen.

if screen-name = <field-name>.

screen-input = 0.

endif.

modify screen.

endloop.

endif.

hii

you can use like

CASE sy-ucomm.
  WHEN 'DISPLAY'.--->your Button name
    LOOP AT SCREEN.
      IF screen-name CS 'p_docno'-->here like this you can write for all your screen elements by using AND addition.
        screen-enable = 0.
        MODIFY SCREEN.
      ENDIF.                           " IF screen-name CS 'p_docno'.
    ENDLOOP.                           " LOOP AT SCREEN.
  
  WHEN 'CHANGE'..--->your Button name

    LOOP AT SCREEN .
      IF screen-name CS 'p_docno'.
        screen-enable = 1.
        screen-input = 1.
        MODIFY SCREEN.
      ENDIF.                           " IF screen-name CS 'p_docno'.
    ENDLOOP.                           " LOOP AT SCREEN .
  
ENDCASE.

hi,

Use case endcase.

Firstly you will have to put the fields you want in display and change mode in the screen painter (SE51)and then use that group name in the screen-group1 parameter.

Case sy-ucomm.

when 'DISPLAY'.

LOOP AT SCREEN.

IF screen-group1 = 'DIS'.

screen-input = '0'.

MODIFY SCREEN .

ENDIF.

ENDLOOP.

when 'CHANGE'.

LOOP AT SCREEN.

IF screen-group1 = 'CHA'.

screen-input = '1'.

MODIFY SCREEN .

ENDIF.

ENDLOOP.

Endcacse

Hope this helps you

hi,

You can keep this piece of code in the PBO (PROCESS BEFORE OUTPUT) since you have to modify the screen attributes as soon as you click on the particular pushbutton so that you can further do the changes on to the screen as per your need.
