How to provide date and time stamp to the extracted file.

Question

I 'm downloading data from DB to Flat file using GUI_DOWLOAD. whenever it is executed it is creating with a file name.
if i rerun the program the file is overwriting with the same name.
now based on the requirement how many times i executed, that many times file should be individually created and should be added with date and time stamp.
like
if when i executed  at the very first time it should saved with filename, date and time.
say "Address.txt 04/05/2007 07:55:10"
When i executed it for second time it doesn't overwrite the file.
it should create a new file.
like "Address.txt 04/05/2007 07:59:20".
Please guide me the way if possible code.
Thanks in advance.

Hi Vamsi,
               Use FM 'F4_PROGRAM' to take file from the user .
In this case user will enter the file name. u can append date & time to that file path.
Refer this code.
CALL FUNCTION 'F4_FILENAME'
    EXPORTING
      PROGRAM_NAME  = SY-REPID
      DYNPRO_NUMBER = SYST-DYNNR
    IMPORTING
      FILE_NAME     = P_P_FILE.
concatenate P_FILE '04/05/2007 07:59:20' into V_FILE.
CALL FUNCTION 'GUI_DOWNLOAD'
    EXPORTING
      filename                        = v_file
     filetype                        = 'ASC'
      write_field_separator           = 'X'
    TABLES
      data_tab                        = i_tab
  IF sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
        WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.
  IF sy-subrc = 0.
    MESSAGE i002.
  ENDIF.
