Product description
From the Publisher
Written by two leading experts and approved by SAP's ABAP Language Group, ABAP Objects provides an in-depth and comprehensive introduction to SAP application programming for Release 4.6. The focus is on ABAP Objects, which is treated here not as an add-on, but as an integral part of the ABAP language.
An indispensable guide for novice and experienced programmers alike, ABAP Objects includes coverage of these essential topics:
The new ABAP Workbench and the most important features of the ABAP language.
The fundamentals of ABAP programming, including the ABAP runtime environment.
The core ABAP language elements.
The two ABAP programming models - classical and object-oriented - and their relevant statements.
Advanced concepts of OO programming with ABAP Objects.
Programming the SAP user interface.
Database access with OpenSQL.
ABAP glossary and a complete list of system fields.
The book also includes two CDs carrying a fully-operational SAP Basis System, which contains all the example programs from the book. The examples can also be found the publisher's website, along with a FAQ for the CDs.
From the Inside Flap
From SAP
ABAP, the programming language of SAP for business applications, is a language with a long-standing tradition. Having started off over 20 years ago as a reporting language in the mainframe world and having developed between 1985 and 1995 into a complete 4GL with SQL integration and language support for dialog and transaction programming, ABAP is now a modern object-oriented, statically typed yet flexible, portable and universally applicable programming language offering particular support for control- and web-based applications. However, ABAP is more than just a language. It is embedded within a complete development environment with all the editors, tools and repositories needed for large and complex software development projects. A large number of services contained in SAPs application server middleware infrastructure can also be addressed readily and independently of a particular platform. I am delighted that the two authors, Horst Keller and Sascha Krüger, have taken it upon themselves to portray the object-oriented basic structure of modern ABAP alongside the full scope of the programming concepts developed over time in ABAP. Within a single book they offer the reader the distinct advantage of being able to find descriptions of both the new concepts of object-oriented development with ABAP Objects and the older technologies of earlier releases a knowledge of which remains essential due to the volume of ABAP code still in existence. I hope that this book will bring all readers further joy and success in programming in ABAP.Walldorf, August 2000Andreas BlumenthalDevelopment Manager ABAP LanguageSAP AGFrom SHS Informationssysteme AG
Dear ReaderAs a member of the board of SHS Informationssysteme AG it is a particular pleasure for me that our employee Sascha Krüger has found time in his busy schedule to publish the present book on ABAP Objects together with Dr Horst Keller. Practical and customer-driven implementation based on a thorough theoretical grounding in technological developments as well as dedication is the sole basis for any successful project. In the past SAP has played a significant part in the development of standard ERP software and will, in particular through mySAP.com, continue to do so in the future. From the position of our company, SAPs development in CRM (Customer Relationship Management) with new technological and strategic market orientation is of particular interest in this respect. Following the ERP boom of the past two decades, thesecustomer-oriented systems are now in widespread use throughout companies above all in the telecommunications industry with its enormous growth in new customers. Anyone wishing to be successful in this kind of market must come to terms with the SAP Basis technology in order to integrate CRM systems in their existing IT landscape. As many leading companies implement the SAP System, this requires innovative concepts. Not least through the use of EAI (Enterprise Application Integration) tools, object-orientation is being increasingly established as the standard in integration. With ABAP Objects, SAP is intensifying its support of object-oriented (outbound) development and thereby allowing the seamless integration of different object models such as DCOM and CORBA. The present book by Dr Horst Keller and Sascha Krüger is an introduction to the new world of ABAP Objects and will give you an understanding of how to start with or change to a new programming model. Our wish for both authors is that this book will soon become the standard for the new type of object-oriented development under SAP and will become an indispensable resource in practical applications.Munich, August 2000Dr Stefan MöllerSHS Informationssysteme AGMember of the Board
From the Authors
In recent years the ABAP programming language has undergone an enormous development, the latest stage of which has been the gradual introduction of ABAP Objects between Releases 4.0 and 4.6. Of the books concerned with ABAP currently available on the market, only a few really get to grips with the new language concept. Those that refer to ABAP Objects do so only in terms of a supplement to existing material. This situation therefore led us to write the present book on ABAP Objects. As, however, ABAP Objects cannot be considered in isolation from ABAP as a whole, it developed into a comprehensive description of the ABAP programming language based on the current Release 4.6. If you compare the current scope of the language with that of Release 3.0, for which the last official ABAP book KRE96 was written, you will find many other new additions apart from the introduction of ABAP Objects. These include the integration of the ABAP type concept into the ABAP Dictionary, the introduction of new internal tables, the possibility of using GUI controls and not least the redesigned ABAP Workbench, to name but a few. All these new concepts have finally transformed ABAP from a language focused on generating lists and processing transactions to a universally applicable programming language. This development required us to present ABAP from a universal standpoint, with less emphasis on the earlier programming paradigms of reporting and dialog programming. In this context, it has been helpful that the book has been written jointly by an SAP employee and an external consultant. The insider view from a member of the ABAP Language Group, with precise ideas as to how ABAP should be used, has blended well with the view of an external user with a knowledge of ABAP gained from training seminars, previous publications and daily experience. We have used the synergy effect resulting from these different viewpoints to provide you with a thorough and yet practical guide to ABAP Objects. Certainly, we could not have successfully concluded this project without the direct and indirect contribution of many people in drawing up and checking the manuscript. We are grateful to the following colleagues from the "ABAP and GUI" department of SAP who despite their many duties found time to proof-read the sections on their specialized subjects: Thomas Bareiß, Adrian Görler, Mathias Hanbuch, Rolf Hammer, Peter Januschke, Ulrich Koch, Andreas Neubacher, Helmut Prestel, Andreas Simon Schmitt, Werner Schuster, Christoph Stöck, and Ralf Wendelgass. In particular we thank Mrs Kerstin Gebhard from the ABAP Training Development department who read large parts of the manuscript and was always on hand to provide constructive criticism. We would like to thank the students Wolfgang Kiess and Torben Simon for creating the ABAP system field overview and proof-reading some of the chapters. Jürgen Heymann kindly provided us with the object-orientation literature references. We would also like to thank anyone else we have not mentioned but who has suggested improvements along the line. We have Michael Demuths initiative to thank for the fact that the accompanying CDs contain an SAP Basis system including the example programs from this book. Andrea Fritsch entered the examples into the system and created the template. Jürgen Krüger supported us with the downloadable files for the transport request for the example programs. For the program for generating training data we used an ABAP training template from Thilo Buchholz. Lastly, we would like to thank also Tomas Wehren and his team from Galileo Press, in particular Iris Warkus, for their cooperation. For the English edition we would especially like to thank Gabriele Buchner, Michèle Coghlan, and Julie Plummer from Product Management (Development Platforms) for their indispensable commitment during our technical editing of the translated text. Horst Keller would also like to thank the Development Manager of the ABAP Language Group, Andreas Blumenthal, for all his support with the project in providing all the necessary resources and many useful hints. Above all he is indebted to his wife Ute for her patience and encouragement over the many evenings and weekends he spent working on the book. Sascha Krüger would like to thank Stefan Möller, board member of SHS Informationssysteme AG, and the manager of the Cologne office, Frank Pensel, for their support. He would also like to thank his SHS project team for their excellent cooperation which allowed him to spare the time for writing this book. Particular thanks go to his wife Katja who continued to support his authoring commitments throughout, despite the restrictions it placed on their private life.Horst KellerWalldorf, August 2000Sascha KrügerCologne, August 20000201750805P04152002

I DID HAVE PROBLEMS!!!
1)installing the CDs. I am using Windows XP and had coupla glitches.
1) you should add the ip address and computer name to the /etc/hosts file on your computer. It can be found in the system32 folder.
2) You probably need to copy the contents of the Data CD(2) to hard disk (incase you dont have 2 CD drives. And specify the location of the data files during instalation.
2) Problem creating Objects: I did have problems creating Objects..It was frustrating for a while. Then I figured out the solution after some online research.
a) Try to apply the patch then comes with the CD.
b) renaming my files to start with z_ solved the problem
To be fair, perhaps not having previous SAP experience and the basic knowledge that comes with it is hindering my understanding.
This book was first written in German in late 2000 and only recently translated into English. Perhaps there has been something lost in the translation.
I think it's fabulous.
However, when SAP introduced the object oriented ABAP I was totally lost. And I choose this book as a guide to learn ABAP OO, after going through all the chapters and examples I am getting to understand OO much better now. The attached CDs are not only useful to learn object oriented coding, I also utilize it to learn workflow by myself.
It's a nice book as a starting point to learn ABAP OO!
A well structured content and a simple approach to explain the new ABAP concepts are probably the best ways to describe the book. The CDs contain a complete SAP System which is a great way to get lot's of practise.
The software that comes along with the book, does not work with windows-xp if xp has all of the latest upgrades and patches from microsoft!?!!?.
The so called "Object list" will not show!
There are patches available for MiniSAP to cure this problem, but it is impossible to get the patches to minisap witout a licence, and you don't get a licence along with minisap!!!!????
What a waste off money and time! I should have read these reviews before buying the useless book and software!
Shame on the SAP comunity and on the authors of this book!!!
Amazon.com should warn buy'ers with "up to date XP" on their computer!

感覚で翻訳しながら、動作検証等をしました。
何よりも重要なのは、付属のCD-ROMにて、
R/3の基本的な開発・テストが出来る点です。
環境は、WINDOWS 2K/XPです。
通常業務のモジュールは使用出来ませんが、ABAP言語を
動作させながら検証できるので、
学習用としては十分購入価値はあると思います。
※おまけ情報※
R/3バージョン46D相当です。
テキストエレメント等での日本語(全角)は使用不可。
(文字が化ける。但し、ABAPソース上は使用可能)
