Hi Moni,

Please check the following code

CASE sy-ucomm.
    WHEN 'SELECTALL'.
      DO w_lines TIMES.
        READ LINE sy-index FIELD VALUE w_check.

        IF w_check EQ space.
          checkbox = 'X'.
          MODIFY LINE sy-index FIELD VALUE w_check FROM w_check.
        ENDIF.  
                       
      ENDDO.                           

    WHEN 'DESELECT'.
      DO w_lines TIMES.
        READ LINE sy-index FIELD VALUE w_check.
          checkbox = ' '.
          MODIFY LINE sy-index FIELD VALUE w_check FROM w_check.           
      ENDDO.       

    WHEN 'REFRESH'.
      DO w_lines TIMES.
        READ LINE sy-index FIELD VALUE w_check.

        IF w_check EQ 'X'.
          CLEAR checkbox.
          MODIFY LINE sy-index FIELD VALUE w_check FROM w_check.
        ENDIF.

hi,

try the below code in AT USER-COMMAND Event.

AT USER-COMMAND.

Case Sy-ucomm.

when 'SELECTALL'.

loop at itab into wa.

wa-chkbox = 'X'.

modify itab from wa.

endloop.

When 'DESELECTALL'.

loop at itab into wa.

wa-chkbox = space.

modify itab from wa.

endloop.

When 'REFRESH'.

Rebuild the internal table.

endcase.

chkbox is the char field of length 1 for checkbox

Hi Moni,

Try this simple LOOP (at the event AT USER-COMMAND):

FIELD-SYMBOLS: <fs> type itab. 

LOOP AT itab ASSIGNING <fs>. 
  IF sy-ucomm = 'SELECTALL'. 
    <fs>-checkbox = 'X'. 
  ELSEIF sy-ucomm = 'DESELECT'. 
    CLEAR: <fs>-checkbox.          checkbox = ' '. 
  ELSEIF sy-ucomm = 'REFRESH'. 
    <fs>-checkbox = <default>.   " set your default value (either X or space) 
  ENDIF. 
ENDLOOP.

Using the ASSIGN clause you have NOT to MODIFY your itab table! Because <fs> points directly to the current line.

Try it and have success,
