Title: No help at all..only theoretical nonsense & impractical e.g.
Review: How can you write a book about ALE, EDI and IDOC and not explain the fundamental concepts of IDOCs properly? The IDOC section has been relegated to the last few pages with no clear explanation. The ALE is sketchy at best, and the EDI is more than half of the book with mostly useless info. The cover claims to cover 4.X but there is no coverage at all - the info is still 3.0 - no mention of the expanded EDIDD record structure of 4.X at all! You have to go from page to page to find anything - no clearly defined structure of the info. Unmethodical and illogical sequence.
Is the review positive or negative?
