Function Module to edit the ALV Output

  I have an ALV report output.I need the edit values based on some conditions in the ALV output and 
  save the changes. Is there any function module to edit the output and proceed further.

First create the field catalog of the field that you want to edit in this way
WA_fieldcat-fieldname  = 'MENGE'.
  WA_fieldcat-qfieldname = 'MEINS'.
  WA_fieldcat-seltext_m  = 'PO Quan.'
  WA_fieldcat-edit = 'X' .
Secondly you keep a custom button like 'SAVE' in the toolbar and  also try to keep a checkbox in your ALV.
for checkbox you have to keep a following code snippet in your finallly displayed interanal table:
chk(1)    TYPE c, and in the fieldcatalog you have to write following piece of code
  WA_fieldcat-fieldname = 'CHK'.
  WA_fieldcat-seltext_m = 'CheckBox'.
  WA_fieldcat-checkbox = 'X'.
  WA_fieldcat-edit = 'X' .
  WA_fieldcat-input = 'X'.
  WA_fieldcat-tabname = 'IT_FINAL'.
  WA_fieldcat-col_pos = 1.
then you have to set the parameter i_callback_user_command           = 'USER_COMMAND'
of FM REUSE_ALV_GRID_DISPLAY.
Then write a subroutine like the following one to handle the SAVE operation
FORM user_command USING I_r_ucomm LIKE sy-ucomm
                  rs_selfield TYPE slis_selfield.
DATA:l_cntr TYPE i.
CASE I_r_ucomm.
WHEN '&ZXZ'.
      CLEAR l_cntr.
      CLEAR WA_final.
      LOOP AT IT_final INTO WA_final.
        IF WA_final-chk = 'X'.
          l_cntr = l_cntr + 1.
        ENDIF.
      ENDLOOP.
      IF l_cntr GT 1.
        MESSAGE i011.
      ELSEIF l_cntr = 1.
           READ TABLE IT_final INTO WA_final WITH KEY chk = 'X'.
           MODIFY IT_final FROM WA_final TRANSPORTING menge
          WHERE chk = 'X'.
          CLEAR WA_final.
          PERFORM disp_alv. <<<This is to display the refreshed alv after saving your data
     endif.
ENDCASE.
ENDFORM.
