In 2007 as part of SAP NetWeaver 7.10, SAP has introduced a new software development kit (SDK) for remote function call (RFC) communications:
SAP NetWeaver RFC SDK. It is the successor to the well-known "classic" RFC SDK for SAP R/3, and you can use it in C/C++-based applications to communicate with SAP back-end systems ranging from SAP R/3 4.0B to the latest SAP NetWeaver systems. The following article has originally been published in 2007 by SAP Professional Journal and appears here with permission of the publisher, Wellesley Information Services. It takes a deeper look at the design of SAP NetWeaver RFC SDK and explains the ideas behind it.
The first part describes how
- metadata (data types, structure definitions, descriptions of function module signatures) is handled by the NW RFC SDK
- data (fields, structures, tables) is handled by the NW RFC SDK
- C/C++ programs can send RFC requests into the ABAP back-end system
- C/C++ programs can process the response or various exceptions returned by the ABAP back-end system
