        key         = key
      IMPORTING
        destination = pswd.

    CALL FUNCTION 'FTP_CONNECT'
      EXPORTING

Communication error, password error, URL error, software error, authorization error, ... Who knows?

By the way, you don't handle all the exceptions, and you also lose information about the exact reason like tcpip_error, command_error, etc.

Check that the FTP works by using the program RSFTP001. There are other RSFTP* utility programs.
