FTP using ABAP

Question

Hi Gurus,
We are trying to read a file from a server (e.g) XYZ.123.com and other details which are provided to us are user name (e.g): Abc123 and Directory (e.g): /123/123/123/123l.
My question is: Do we need a RFC connection to the server if yes then what type of RFC connection? If RFC connection is not required then what we have to do to establish the connection.
Thanks,
Abhishek.

Hi Abhshk, there may be a more modern way but something like this has worked in the past
*-- FTP_CONNECT requires an encrypted password to work
  call 'AB_RFC_X_SCRAMBLE_STRING'
       id 'SOURCE' field mc_password
       id 'KEY' field mi_key
       id 'SCR' field 'X' id 'DESTINATION' field mc_password
       id 'DSTLEN' field mi_pwd_len.
  call function 'FTP_CONNECT'
       exporting
*-- Your SAP-UNIX FTP user name (case sensitive)
         user            = 'unixuser'
         password        = 'unixpassword'
*-- Your SAP-UNIX server host name (case sensitive)
         host            = 'saphost'
         rfc_destination = 'sapsystemrfc'
       importing
         handle          = mi_handle
       exceptions
         not_connected   = 1
         others          = 2.
  check sy-subrc = 0.
  call function 'FTP_COMMAND'
    exporting
      handle        = mi_handle
      command       = 'dir'
    tables
      data          = mtab_data
    exceptions
      tcpip_error   = 1
      command_error = 2
      data_error    = 3
      others        = 4.
