Problem in Dloading O/P

Question

Hi all,
I am trying to save a Classical report output as a excel file using CALL METHOD. wat i want is to give functionality to the user so he can select his own path to save the excel file. I was successful till that. but after it is saved, i am unable to open it. But if i copy and save the same excel i am able to open and see the output in excel. Can any one tell wat might be wrong??
I would hav copied the code but its too big to post it in the thread.
Also please tell me wat Call methods to be applied to download and save the O/P as excel.
I am using
  DATA: NAME TYPE STRING,
        PATH TYPE STRING,
        FULLPATH TYPE STRING,
        EXT TYPE STRING,
        FILTER TYPE STRING,
        SIZE TYPE I,
       GUIOBJ TYPE REF TO CL_GUI_FRONTEND_SERVICES,
        UACT TYPE I
        SHEET TYPE OLE2_OBJECT.
  CONDENSE V_FILE NO-GAPS.
  EXT = 'xls'.
  CALL METHOD CL_GUI_FRONTEND_SERVICES=>FILE_SAVE_DIALOG
    EXPORTING
      DEFAULT_EXTENSION = EXT
      DEFAULT_FILE_NAME = NAME
      FILE_FILTER       = FILTER
    CHANGING
      FILENAME          = NAME
      PATH              = PATH
      FULLPATH          = FULLPATH
      USER_ACTION       = UACT.
  V_FILE = FULLPATH.
  CALL METHOD CL_GUI_FRONTEND_SERVICES=>DIRECTORY_EXIST
    EXPORTING
      DIRECTORY            = V_FILE
    RECEIVING
      RESULT               = W_RESULT
    EXCEPTIONS
      CNTL_ERROR           = 1
      ERROR_NO_GUI         = 2
      WRONG_PARAMETER      = 3
      NOT_SUPPORTED_BY_GUI = 4
      OTHERS               = 5.
  IF SY-SUBRC EQ 0.
    CONCATENATE 'Excel Saved at' V_FILE 'successfully' INTO MSG SEPARATED BY SPACE.
    MESSAGE MSG TYPE 'I'.
  ENDIF.
*Save excel speadsheet to particular filename
  CALL METHOD OF SHEET 'SaveAs'
                  EXPORTING
                            #1 = V_FILE     "filename
                            #2 = 1.                          "fileFormat
Save Excel document
CALL METHOD OF SHEET 'SAVE'.
Quits out of Excel document
  CALL METHOD OF SHEET 'QUIT'.
Closes visible Excel window, data is lost if not saved
  SET PROPERTY OF APPLICATION 'visible' = 0.
Thank you.
Best regards

If I understand well what you say, you just don't use the correct technology : if your report displays a classic output (I understand it's a "list" based on WRITE abap statement?), you can't juste use OLE (call method of) to convert and save the list to an excel file. You must use CL_GUI_FRONTEND_SERVICES=>GUI_DOWNLOAD method, passing an internal table with comma separated values.
