Can I use NW SDK client 7.5 for accessing NW 7.4 SAP server?

I have SAP NETWEAVER 7.4 installed on my SAP. Can I use 7.5 client libraries to connect to the server? I have tried to connect to the server using SapNwRfc library, but got an exception "RFC_LOGON_FAILURE with message: 00024error during logon". Any help would be appreciated.

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.
