I've never written a review before, but this book is so bad I feel obligated to save others from being ripped off. (I'm shipping mine back). The book is very weak. Not only are there few pages, but the type is probably 20pt, and there is much white space. Further, there is no substance as these are only answers to questions that were likely sent to a support desk. (An example from pg 34: "how is the ABAP Authority-check used?". There is a two sentence answer, and the rest of the page is empty. If this is any indication of the quality of other sapcookbook.com books, I'd advise to stay away from all of them.
