Query: Book for SAP Version 4.0; needs updating

Bought the book in March 2002 and much to my surprise, this book deals with R/3 Version 4.0. Given the CATT tool and workbench went through a major overhaul in versions 4.5 and 4.6 (including the addition of a new, simplified transaction), this should be recognized. If your buying this for the tool, be aware.
