Cl_gui_frontend_services= gui_download - wrong behaviour with Windows UAC

Question

Hello,
we are using the method cl_gui_frontend_services=>gui_download to store files on the presentation front end (Windows Vista with UAC).
When the user has no windows rights to the target directory and UAC is active, then the method gui_download stores the file in other directory (C:\Users\<USER_NAME>\AppData\Local\VirtualStore\Windows) and returns with sy-subrc = 0.
In our opinion this is a critical problem but SAP doesn't want to correct it.
What do you think about it?
regards,
Kris

Hello kpsgoutam ,
thank you for your post but it's not an answer for my question. I know how to use 'gui_dowload'. The problem is, it works wrong with UAC and target directory, where you have no rights to write the file.
Consider following code:
REPORT ztest.
DATA:
" to reproduce the problem the UAC must be active
" and you can't have write rights to the target directory
  lv_filename TYPE string VALUE 'c:\windows\test.txt',
  lt_data     TYPE TABLE of string,
  lv_data     TYPE string,
  lv_outlen   TYPE i.
lv_data = 'Some test content'.
APPEND lv_data TO lt_data.
CALL METHOD cl_gui_frontend_services=>gui_download
  EXPORTING
    filename                  = lv_filename
  IMPORTING
    filelength                = lv_outlen
  changing
    data_tab                  = lt_data
  EXCEPTIONS
    file_write_error          = 1
    no_batch                  = 2
    gui_refuse_filetransfer   = 3
    invalid_type              = 4
    no_authority              = 5
    unknown_error             = 6
    header_not_allowed        = 7
    separator_not_allowed     = 8
    filesize_not_allowed      = 9
    header_too_long           = 10
    dp_error_create           = 11
    dp_error_send             = 12
    dp_error_write            = 13
    unknown_dp_error          = 14
    access_denied             = 15
    dp_out_of_memory          = 16
    disk_full                 = 17
    dp_timeout                = 18
    file_not_found            = 19
    dataprovider_exception    = 20
    control_flush_error       = 21
    not_supported_by_gui      = 22
    error_no_gui              = 23
    others                    = 24.
WRITE: / 'sy-subrc =', sy-subrc. " error: with active UAC the sy-subrc is 0
