ABAP/4: Programming the Sap R/3 System

Author: Bernd Matzk

Many of the introductory SAP books currently on the market provide only a brief overview of ABAP. In ABAP/4 Programming the SAP/3 System, Bernd Matzke builds on this information to look in depth at the programming language at the heart of the SAP R/3 system.

This new and fully updated edition of the definitive guide to ABAP/4 aims to make the fundamentals of this evolving programming language accessible to anybody developing or maintaining an SAP R/3 system. Starting with the basic principles, it explains the essential characteristics of ABAP/4 and the SAP programming concept.

With this book you will learn how to:

· Master the ABAP/4 commands in order to analyze existing standard applications and write new programs
· Understand function modules to use program code from other applications
· Create your own programs and construct your own test environments with an expansive set of examples designed to build up knowledge and programming skills

NEW! Covers new concepts affecting the development environment and program, in line with R/3 Release 4.6
NEW! Covers features of completely redesigned user interface
NEW! Reference section covering ABAP commands in Release 4.6B
NEW! CD-Rom containing source code of all examples plus SAP transport files with examples

The sample programs in this book were developed on a 4.6B-system but can also run on other versions of the R/3 system.

Computer Networking Lab Manual Package

Author: James F Kuros

Computer Networking provides a top-down approach to this study by beginning with applications-level protocols and then working down the protocol stack. Focuses on a specific motivating example of a network-the Internet-as well as introducing students to protocols in a more theoretical context. New short "interlude" on "putting it all together" that follows the coverage of application, transport, network, and datalink layers ties together the various components of the Internet architecture and identifying aspects of the architecture that have made the Internet so successful. A new chapter covers wireless and mobile networking, including in-depth coverage of Wi-Fi, Mobile IP and GSM. Also included is expanded coverage on BGP, wireless security and DNS. This book is designed for readers who need to learn the fundamentals of computer networking. It also has extensive material, on the very latest technology, making it of great interest to networking professionals.
