Hey Sayandeep,
  In the Flow Logic Process Before Output (PBO) create one module or in Module status_0101 write this code.
V - Change
A - Display
H - Create
if i_trtyp = 'A'.
    loop at screen.
      if screen-name = 'Screen Field Name'.
        screen-input = 0.
        modify screen.
      endif.
    endloop.
  else.
    loop at screen.
      if screen-name = 'Screen Field Name'.
        screen-input = 1.
        modify screen.
      endif.
    endloop.
  endif.
Note: Try to avoid hot coding the transaction Code.
