FTP with standard table of string.

Hi Experts,

I need help in transferring a standard internal table of type string to an FTP server.

I connect to the FTP successfully and the file is created but it is empty!

here is the part of the code I am using:

 data: itab_file type standard table of string.


 call function 'FTP_R3_TO_SERVER'
    exporting
      handle         = mi_handle
      fname          = '1.tmp'
      character_mode = 'A'        "not working
      character_mode = 'X'         "not working 


    tables
      text           = itab_file[].      "not working
      text           = itab_file.        "not working

Thanks.
