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.

1Have you checked [this](https://support.sap.com/en/product/connectors/nwrfcsdk.html)?. Scroll down to the documentation section. – tomerpacific Mar 07 '23 at 07:59

Yes I have, and I have assumed that it could have something to do with necessary authorizations, but I also need to know whether is it safe to use the newer version (7.5) of SDK against the older one (7.4) on the server? – kidbabic Mar 07 '23 at 09:04

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.
