Hi Sudhir,
Well, you can clear the history of the input fields and do some validations on those fields which will throw some custom error message if the user is trying to enter invalid values.
For clearing the history, you can use the below snippet in PBO
data: rc type i.
  call method cl_gui_frontend_services=>disablehistoryforfield
    exporting
      fieldname                     = 'GW_OBSHEAD-VBELN'
      bdisabled                     = abap_on
    changing
      rc                            = rc
    exceptions
      field_not_found               = 1
      disablehistoryforfield_failed = 2
      cntl_error                    = 3
      unable_to_disable_field       = 4
      others                        = 5.
  if sy-subrc <> 0.
  endif.
