The new SAP NetWeaver remote function call (RFC) software development kit (SDK) provides a reliable and highly efficient communications protocol for exchanging data between C/C++-based applications and SAP systems. This article, the final installment in a three-part series, looks at some advanced SAP NetWeaver RFC SDK topics, including how to handle transactional RFC (tRFC) and queued RFC (qRFC), construct hard-coded metadata descriptions, handle RFC callbacks, and use single sign-on (SSO) and Secure Network Communication (SNC). You will also find out how the iDocClient and iDocServer programs work and how to test them.

Ulrich Schmidt

Ulrich Schmidt joined SAP in 1998 after working in the field of computational algebra at the Department of Mathematics, University of Heidelberg. Initially, he was involved in the development of various products used for the communication between SAP R/3 systems and external components. These products include the SAP Business Connector, which translates SAP’s own communications protocol RFC into the standard Internet communications protocols HTTP, HTTPS, FTP, and SMTP, as well as pure RFC-based tools, such as the SAP Java Connector and RFC SDK. Ulrich gained insight into the requirements of real-world communications scenarios by assisting in the setup and maintenance of various customer projects using the above products for RFC and IDoc communications.
