SAP NetWeaver Remote Function Call (RFC)
Software Development Kit (SDK)

The SAP NetWeaver RFC SDK offers a C/C++ interface for connecting to SAP systems from release R/3 4.6C up to today's SAP S/4HANA systems. It allows to develop programs that call ABAP functionality (RFC clients) as well as programs that can be called from ABAP (RFC servers).

The most important features of the SAP NetWeaver RFC SDK are:

  • Working with the native RFC protocol
  • Large protocol functionality - for example, all relevant features of RFC in SAP systems are also supported by the SAP NetWeaver RFC SDK
  • High performance
  • High flexibility

The SAP NetWeaver RFC SDK is thread-safe. This enables the user to write powerful multi-threaded RFC applications.

The SAP NetWeaver RFC SDK is not compatible with the "classic" RFC Library. Existing applications using the classic RFC Library need to be adjusted if you want to convert them to the SAP NetWeaver RFC SDK.
