SAP連接FTP服務器

SAP系統中連接FTP服務器需要配置表SAPFTP_SERVERS,在這個表中添加ftp服務器及端口，然後使用如下代碼連接ftp服務器

   
   constants cons_key type i  value 26101957.

    data:lv_pwd(64)   type c,
         lv_handle    type i,
         lv_length    type i,
         lv_pwdlen    type i.

    lv_pwd = is_ftpinfo-password.
    lv_pwdlen = strlen( lv_pwd ).

*密碼加密
    call function 'HTTP_SCRAMBLE'
      exporting
        source      = lv_pwd
        sourcelen   = lv_pwdlen
        key         = cons_key
      importing
        destination = lv_pwd.

    do 3 times." 連接三次，以爲一次可能會不成功

      call function 'FTP_CONNECT'
        exporting
          user            = is_ftpinfo-username
          password        = lv_pwd             "PASS WORD
          host            = is_ftpinfo-host
          rfc_destination = 'SAPFTPA'        "DEFAULT
        importing
          handle          = ev_handle
        exceptions
          not_connected   = 1
          others          = 2.

      if sy-subrc = 0.
        exit.
      endif.
    enddo.

    rv_subrc = sy-subrc.
