- Explore the technical procedures and settings for creating and securing RFMs in ABAP: Part 2 — A comprehensive guide
for SAP programmers and administrators
by Masoud Aghadavoodi Jolfaei, Development Architect, SAP AG
Eduard Neuwirt, Senior Developer, SAP AG
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.
- Improve communication between your C/C++ applications and SAP systems with SAP NetWeaver RFC
SDK: Part 1 — RFC client programs
by Ulrich Schmidt, Senior Developer, SAP AG
Guangwei Li, Senior Developer, SAP AG
SAP NetWeaver 7.1 introduces 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 enable communication with SAP back-end systems ranging from SAP R/3 4.0B to the latest SAP NetWeaver systems. This article is the first in a three-part series that examines the advanced features of SAP NetWeaver SDK and the communication between SAP systems and external C programs. This first installment looks at the design of SAP NetWeaver RFC SDK and explains the ideas behind it.

You will learn how they automatically retrieve and cache structure information, receive calls from multiple SAP systems into one server program, protect the server from unauthorized access, and trigger all kinds of exceptions from the server. You will also find out how the RFC SDK makes it easy for RFC server applications to handle errors and gives the ABAP side of the system meaningful details about any error situations.

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.
- Improve your business processes with quick and easy enhancements to PDF documents: A toolbox
for modifying PDF files
using ABAP
by Cord Jastram, Software Engineer,
Computer Sciences
Corporation, Germany
Forms are the lifeline of modern business, and
the well-known PDF technology enables you to easily
send forms via email, post them on the Internet,
archive them, or print them offline. But what if
you want to quickly modify a PDF document — add encryption,
attachments, or background text, for example — without
having to open Adobe Acrobat and click through the
various buttons and menu items? This article introduces
the PDF Toolbox, an open-source solution that allows
ABAP developers to programmatically modify existing
PDF documents with ease. It takes you through the
components of the solution, walks you through an
example that uses it, and shows you how to enhance
and deploy it.
- Increase the efficiency of your RFC communications with bgRFC — a scalable and transactional
middleware framework
by Wolfgang Baur, Developer,
Omar-Alexander Al-Hujaj, Developer,
Wolfgang Röder, Development Architect, SAP AG
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.
