Your data is one of your most valuable assets, so you protect it by separating it into systems with varying levels of security, depending on the sensitivity of the information. But what if processes running in lower-level security areas need to access data stored in higher-level security areas? This article shows you how to use SAP NetWeaver Process Integration (PI) 7.0 in conjunction with a security gateway to ensure the safe transfer of data between high and low security domains. PI serves as a flexible and transparent integration platform while the security gateway acts as a firewall, enabling data to cross domain boundaries without compromising security.

Although new communication protocols such as HTTP, HTTPS, and SOAP have gained traction in recent years, remote function call (RFC) remains the most trusted and widely used for connecting ABAP systems. This is the second article in a two-part series that helps you create better performing and more robust ABAP applications using RFC. The first installment introduced key RFC concepts and discussed the five RFC types. This second installment explores more advanced topics. It shows you how to design and develop remote function modules (RFMs) that fulfill performance and security expectations, and how to properly maintain RFC destinations for effective network communication.

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.
