Need to use readline

Question

Hi all,
I have a report output, in this output, the amount field is input on, so i can change the value for amount in output.
If i change the amounts in one or two lines in output, the subtotal value should be changed simultaneously. For this i need to capture the lines that are changed with amount and i need to do calculation again in the program and the subtotal line in the output should be modified accordingly.
Pls let me how to do this
Thanks

HI Saravana,
Put this code in sy-ucomm .This code will give u the changed values in the internal table which u have used for diaplaying the gird.
DATA temp1(9) TYPE n.
DATA: tem_qty LIKE mseg-menge.
  DATA: seltab     TYPE TABLE OF rsparams,
        seltab_wa  LIKE LINE OF seltab.
*DATA:rs_selfield TYPE slis_selfield.
  it_plafc[] = it_plaf[].
  IF ref_grid IS INITIAL.
To get a reference to the actual ALV if is not referenced yet
    CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
      IMPORTING
        e_grid = ref_grid.
  ENDIF.
  IF NOT ref_grid IS INITIAL.
To get all data changed
    CALL METHOD ref_grid->check_changed_data.
  ENDIF.
After this u once again call the function for dispalying the grid .
The new grid will show all the changed values in the grid with totals and subtotals..
