Remote function call (RFC) is the de facto protocol of choice of SAP developers, system architects, and administrators, and is the basis of nearly all major integration points in an SAP system landscape. You’ve probably used RFC to call function modules on other SAP systems, or used one of SAP’s standalone RFC libraries. But did you know that there are other SAP-supplied RFCs that optimize system resources and performance? This article, the first in a two-part series, takes you on a brief tour of the five RFC types available with SAP Basis 4.0B and higher, and teaches you how to use them in your ABAP programs.
