SAP RFC APIs: "Classic" RFC Library and NetWeaver RFC SDK

To enable different computer systems where one of them is SAP to communicate each other so called Remote Function Call (RFC). The RFC is the standard SAP interface for communication between SAP systems. RFC calls a function to be executed in a remote system.

Initially there was only an RFC library which is called now "classic" RFC Library (see my very old blog http://blog.maruskin.eu/2011/11/where-to-download-librfc32dll-rfc.html) is obsolete and replaced by SAP NetWeaver RFC Library.

Later the SAP NetWeaver RFC Library was introduced that is used to interface SAP systems starting from release R/3 4.0B (in case of NW RFC SDK 7.20) and from release 4.6C (in case of NW RFC SDK 7.50) and above including the newest one (NW 75).
Both the things classic and NetWeaver are doing basically same thing. Using the SDK a function in different programming languages can be written that can read/write data out/to SAP system. The newest version (NetWeaver) of course supports the latest technologist such as:  dynamic meta data retrieval, support of all SAP single code pages, new binary protocol (basXML) reduce of data volume when using complex parameter types (nested data types).

Below see overview of different versions and patch levels o of the SAP NetWeaver RFC Library SDK:
