Product Review
Targeted at the SAP R/3 developer, SAP R/3 ALE and EDI Technologies provides working examples of using and customizing this industrial-strength, enterprise-level package.
The book begins with a quick introduction to Application Linking Enabling (ALE) and the Electronic Data Interchange (EDI) in the SAP R/3 package. By using SAP tools, ALE/EDI developers can query data, move it around within distributed systems, and even create reports with third-party tools. The powerful SAP R/3 package contains data fields that can automate virtually any manufacturing or business scenario. The author introduces Intermediate DOCuments (IDOCs), which provide message-based delivery of data.
Further sections investigate master data distribution (which involves requesting IDOC for particular fields). Throughout the book, the author enumerates the steps required within SAP R/3 to generate data (including screen shots of the R/3 tool at work). He also covers both outbound and inbound processing and how to customize IDOC messages. (This can be done to improve performance, for instance.)
Later the book turns to EDI and explains how to generate electronic reports (such as invoices), as well as how to submit data into R/3 via EDI. The book offers tips and techniques for optimizing data processing within distributed systems and features an appendix listing R/3 message codes and IDOC types (which all go by short mnemonic codes).
Written for the reader who already understands the basics of SAP R/3 but wants to learn more, this book can fill a useful niche for the enterprise developer who wants to see this powerful package at work. --Richard Dragan

Customer Reviews & Comments
I've read both the Arvind Nagpal and Rajeev Kasturi books, and I conclude that the Nagpal book is much better for me, a person who has been doing SAP EDI for several years. I do not know either of these authors. I do not have anything to do with the publishers. I bet this is more than many of the reviewers here can say! I know that sheer bulk is not what we are buying here, but let's do some numbers to examine one aspect of the comparison. The Kasturi book starts with 388 pages. Well over 100 pages in the back are tables out of SAP that we can print any time we want (or save a tree and just pull up a screen). Since I've worked with SAP EDI for a few years, I didn't expect a lot of things to be new to me in the first 3 or 4 chapters, but man, there was nothing even moderatly interesting to me in the early part of the book. That left about 150 pages in the middle that, I'll admit, I only skimmed. But the per-page cost of those few possibly valuable pages is quite high! There was a strong ALE / example flavor to the book. As if someone wrote about a few of their favorite implementations. Now, the Nagpal book starts with quite a few more pages (786). There is NOT a huge section of this book dedicated to stuff I could print out of or look up in SAP. Yes, some of this stuff is 'light' too. And again, I'll admit to skimming a lot of it that I didn't have a pressing need to know right now. And yes, there are quite a few print-screens in the book (but I LIKE print-screens). The bottom line is that I, a person who's been using SAP-EDI quite a while, found the Nagpal title MORE INTERESTING, INFORMATIVE, and found it had MORE INFORMATION than the Kasturi book. --Dale--
