In high-volume process communication scenarios, the most commonly used remote function call (RFC) types are asynchronous RFC (aRFC), transactional RFC (tRFC), and queued RFC (qRFC). However, aRFCs are not guaranteed, and while tRFCs and qRFCs follow the guaranteed “transactional” model in which RFC calls succeed or fail as a group, their scalability is limited. To bridge these gaps, SAP NetWeaver 2004s SP14 introduces the background RFC (bgRFC) type, which improves runtime through efficient, highly scalable, transactional processing of large numbers of sequential function calls. This article explains the most important concepts of bgRFC and shows you how to use bgRFC in your programs to create highly scalable integration solutions.
