SAP ALE, IDOC, EDI, and Interfacing Technology Questions, Answers, and Explanations

I purchased the book to get a flavor of what it would be to develop an interface to SAP. The book provides the reader with a global understanding of how EDI in SAP works. The idea for the project was postponed / abandoned. If the project is resurrected I would search for additional information not available in this book.

The book helped to explain in better detail how some of the concepts unique to SAP software actually work. Worth the price.
