Some of the codes in the book are inaccurate for the current edition of SAP. However. The book itself is an excellent resource for individuals who are just beginning to use/learn SAP or users who have been given access to components of SAP at they haven't had access to before. The book is easy to read with enough screen captures of the system to get a feel for SAP, even if you don't have access to the system when you are reading the book.
