File open error at ftp even the file is not open.....

Question

Hi,
i get the error File open with the fm GUI_UPLOAD while uploading the XML file from FTP server.
What is interesting is that i did not open the file, furthermore i closed all the windows else that sap window,
but still i get the file open error.
We create the xml file when created a new delivery. And this xml file is sent to a bukrs's ftp and they also sent the same xml after some validations done.
When it arrives to our ftp server i make it post goods issue automatically but from yesterday i got the file open error, it was working fine just before today.
What could be the problem?
Hint: Yesterday and previous day files still work fine but files created today are faulty.
Thanks.

Thanks for replies.
My code is that:
call function 'HTTP_SCRAMBLE'
    EXPORTING
      source      = gv_password
      sourcelen   = slen
      key         = gv_key
    IMPORTING
      destination = gv_password.
  describe field gv_password length gv_pwd_len in character mode.
  call function 'FTP_CONNECT'
    exporting
      user            = 'HHH\GrupMMM'
      password        = gv_password
      host            = '10.10.10.10' "assume that is the host
      rfc_destination = 'SAPFTPA'
    importing
      handle          = gv_handle
    exceptions
      not_connected   = 1
      others          = 2.
  if sy-subrc eq 0.
    "concatenate 'put' ld_full_path '[' ld_full_path ']'
    *gv_com = 'lcd C:\MMM\RETURN_FILES'.*
    clear mtab_data.
    free mtab_data.
    call function 'FTP_COMMAND'
      exporting
        handle        = gv_handle
        command       = gv_com
      tables
        data          = mtab_data
      exceptions
        tcpip_error   = 1
        command_error = 2
        data_error    = 3
        others        = 4.
    if sy-subrc eq 0.
    endif.
When i get the list of the return files i get data of each file via gui_upload.
CALL FUNCTION 'GUI_UPLOAD'
        EXPORTING
          filename   = filename
          filetype   = 'BIN'                             
        IMPORTING
          filelength = totalsize
        TABLES
          data_tab   = xml_table[]
        EXCEPTIONS
          FILE_READ_ERROR = 1
          FILE_OPEN_ERROR = 2
          NO_BATCH = 3
          GUI_REFUSE_FILETRANSFER = 4
          INVALID_TYPE = 5
          NO_AUTHORITY = 6
          UNKNOWN_ERROR = 7
          BAD_DATA_FORMAT = 8
          HEADER_NOT_ALLOWED = 9
          SEPARATOR_NOT_ALLOWED = 10
          HEADER_TOO_LONG = 11
          UNKNOWN_DP_ERROR = 12
          ACCESS_DENIED = 13
          DP_OUT_OF_MEMORY = 14
          DISK_FULL = 15
          DP_TIMEOUT = 16.
However i get the open error for all files created today.
By the way, how can i use open dataset instead of ftp commands? How can i see the files at apllication server?
i get the files via IP of the FTP but how can i get files from application server?
Thanks.
