You can give the search help of the application server file.Then u dont have to do any explicit validetion...

You can refer to below code to get the F4 help for application server:

PARAMETERS:  p_phys  RADIOBUTTON GROUP g1.                  " appln server file

PARAMETERS: p_ifile  TYPE   dxfile-filename LOWER CASE.

*---------------------------------------------------------------------
* AT SELECTION SCREEN ON VALUE REQUEST
*---------------------------------------------------------------------
AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_ifile.
  PERFORM help_input_file USING p_locl CHANGING p_ifile.

___________________________________________________

FORM help_input_file  USING    p_phys_file   TYPE c

                      CHANGING p_source_path TYPE any.

    CALL FUNCTION 'F4_DXFILENAME_4_DYNP'
      EXPORTING
        dynpfield_filename = 'P_IFILE'
        dyname             = sy-repid
        dynumb             = sy-dynnr
        filetype           = 'P'
        location           = 'A'.


ENDFORM.                    " help_input_file

Hi Navneeth ,

Try this.

SELECTION-SCREEN BEGIN OF BLOCK b1 WITH FRAME TITLE text-001.

PARAMETERS:file LIKE rlgrap-filename .

SELECTION-SCREEN END OF BLOCK b1.

DATA: v_file_name TYPE string,

v_file_name = file.

CALL METHOD cl_gui_frontend_services=>file_exist

EXPORTING

file = v_file_name

RECEIVING

result = v_return

EXCEPTIONS

cntl_error = 1

error_no_gui = 2

wrong_parameter = 3

not_supported_by_gui = 4

OTHERS = 5.

IF sy-subrc <> 0.

MESSAGE a000 WITH v_file_name text-001.(Specify valid file path)

EXIT.

ENDIF.

IF v_return IS INITIAL.

MESSAGE a000 WITH v_file_name text-002.("Invalid Filename ")
