I really don't think the last couple of reviewers knew what they wanted, when they bought this book.
I've just completed the first SAP course "SAPTEC", and found this a great reference.
It gives you info on most of the basic transaction codes that were covered in SAPTEC, and even gives steps on how to install the trial version of Netweaver.
Although it doesn't mention the few little pitfalls you will get when trying to do so.
For a start, Netweaver 7.01 ABAP trial version, requires a lower java jre then most people will have installed.
Also it states that you need the JRE, but you will actually need to install the JDK 1.5
Apart from this, and adding the relevant path variables in, you can get the trial version running fairly easily.
Once this is installed, you have free reign to play with and familiarise yourself with the basic transactions shown in the book.
Basic things that are missing, are things like, howto set up roles with a new user.
This is useful if you have installed the trial version.
The sections on specific SAP modules I can't comment on, but as an introduction and a reference following the first course, it's pretty good.
Well worth the money!
