Sams Teach Yourself ABAP/4® in 21 Days



Having taught the ABAP/4 certification course to hundreds of beginners and experienced developers at both at SAP and at other institutions, I know the kind of problems and questions you will have when learning this powerful language. By incorporating all the best techniques that I have encountered into this book, I hope to impart that same learning experience to you as well. To that end, this book is chock full of detailed diagrams, full-screen snapshots, working sample programs, narrated screencams, and step-by-step procedures. All the sample programs are also supplied on the CD-ROM so that you can upload and run them on your own system. In addition, the utilities that I supply to all of my classes are included on the CD-ROM, plus some new ones that I have written specifically for the buyers of this book.
ABAP/4, for all of its simplicity on the surface, is a complex language underneath. Because of that, the beginner is often bewildered by its behavior. By understanding how it works below the surface, you will be able to master this language. By understanding the hows and whys, you will gain an understanding few have in this exciting field.
This book will guide you through the intricacies of the ABAP/4 language and environment one step at a time. After you complete each chapter, you will be presented with exercises to reinforce your learning. Working solutions are provided for all exercises on the CD-ROM.
As experienced programmers know, and beginners soon find out, creating ABAP/4 programs often means creating more than just a program. It frequently involves the creation of development objects to support it. Procedures for creating these objects are all explained in exquisite detail using a list of numbered steps. Each step contains the title of the screens you encounter and the expected responses to each command. All procedures are accompanied by a screencam showing you exactly how it is done. Now, not only can you learn by watching me, but you can fast forward and rewind me as well.
The sheer volume of information needed to master ABAP is a daunting task for most, but I have taken the most vital information that you need and separated it into 21 manageable bites. With the knowledge you gain using this book, you will be able to branch out to complex ABAP/4 tasks with a solid understanding as your foundation.
As you go through the material, if you have problems or questions please visit the Internet site There I will post answers to frequently asked questions, and problems you may encounter that have not been covered. If you find an error in this book, or suspect there may be an error, you can find and post errata there.
I hope you will find using this book as enjoyable as I have found writing it. Cheers. Here's to your ABAP/4 in 21 days!
