SAP 连接FTP服务器上传文件示例（先决条件和解决办法）
原文链接：https://code84.com/257785.html
1.先决条件
1.确保在系统种实施了note：1605054的代码更正
---------------------关于第一点的报错补充 start----------------------
abap ftp 提示：用户 & 没有访问计算机 & 的权限 或者提示：REC到程序SAPFTP失败
项目中，在没有升级到EHP6 on HANA时，FTP上传程序正常运行，升级后，遇到了以下问题，历经磨难，终于得以解决，分享一下，供用到的兄弟做个参考
升级后，提示：用户 & 没有访问计算机 & 的权限，比较了一下代码：升级后的函数FTP_CONNECT增加了一些校验，需要在透明表SAPFTP_SERVERS中维护ftp地址和端口，上网查了一些资料，说是要打note，basis下载后，最后版本支持到740，而目前用的是750，索性写段代码直接把表给维护了，代码如下：
DATA:lt_sapftp_servers TYPE TABLE OF sapftp_servers WITH HEADER LINE.
lt_sapftp_servers-ftp_server_name = ‘’. "ftp服务器地址
lt_sapftp_servers-ftp_server_port = ‘’. "ftp服务器端口
lt_sapftp_servers-description = ‘’.
APPEND lt_sapftp_servers.
CLEAR lt_sapftp_servers.
MODIFY sapftp_servers FROM TABLE lt_sapftp_servers.
IF sy-subrc EQ 0.
MESSAGE ‘成功’ TYPE ‘I’.
ENDIF.
或者直接SM30去视图 SAPFTP_SERVERS_V 里维护（看下面第三点）
如果你的GUI升级到750，对不起，还可能能遇到一个SAPFTP的问题，SAPFTP.exe必须用最新的，否则，会提示：”RFC 到程序 SAPFTP 失败“的错误
下载地址(要钱的)：http://download.csdn.net/download/champaignwolf/10048563
注意：下载到本地后， C:\Program Files (x86)\SAP\FrontEnd\SapGui 下面找到SAPftp.exe 进行替换（解决SAP750客户端REC到程序SAPFTP失败）
---------------------关于第一点的报错补充 end----------------------
2.确保通过SM59创建了RFC连接：可通过执行标准程序RSFTP005，自动创建两个名为SAPFTP和SAPFTPA的TCP/IP的RFC连接
3.确保表SAPFTP_SERVERS允许连接指定FTP；设置*表示允许所有FTP连接：可通过SM30视图：SAPFTP_SERVERS_V维护表SAPFTP_SERVERS
4.确保FTP服务器网络可达，服务端口正常开启并可访问
5.在程序 RSFTP002 先测试连接

5.科普一下ABAP 把内表转换成其它格式的函数
就是把内表转换成二进制，有以下方法可以使用：
SAP_CONVERT_TO_CSV_FORMAT
SAP_CONVERT_TO_TXT_FORMAT
SAP_CONVERT_TO_TEX_FORMAT
SAP_CONVERT_TO_XLS_FORMAT
SAP_CONVERT_TO_XML_FORMAT
SCMS_TEXT_TO_BINARY
SCMS_XSTRING_TO_BINARY
