Can I use NW SDK client 7.5 for accessing NW 7.4 SAP server?
问题
我在我的SAP上安装了SAP NETWEAVER 7.4。我能使用7.5客户端库连接到服务器吗？
我尝试使用SapNwRfc库连接服务器，但出现异常“RFC_LOGON_FAILURE，消息为：00024登录期间发生错误”。
感谢任何帮助。

"RFC_LOGON_FAILURE with message: 00024error during logon".
Any help would be appreciated.

SAP的RFC协议是向下兼容的。一般来说，您可以在较旧的NetWeaver AS ABAP版本上使用NW RFC SDK 7.50，至少可以向后兼容至真正陈旧的R/3版本4.6。
当然，如果使用一些较新的RFC协议功能（例如WebSocket RFC），那么ABAP后端也必须支持它。可用的RFC功能在协议的内部RFC标头中向合作伙伴发出信号。
如果您遇到RFC_LOGON_FAILURE，这是由于其他原因，取决于后端的配置和所使用的RFC登录参数，而不取决于所使用的NW RFC库版本。
英文:
SAP's RFC protocol is downwards compatible. In general, you can use NW RFC SDK 7.50 also for newer and older NetWeaver AS ABAP releases at least back to the really old R/3 release 4.6.
Of course, if using some newer RFC protocol features (like WebSocket RFC for example), then also the ABAP back-end has to support it. Available RFC features are signaled to the partner in the protocol's internal RFC headers.
If you are getting an RFC_LOGON_FAILURE, this has other reasons and depends on the back-end's configuration and the used RFC logon parameters, but not on the used NW RFC library version.
