This is not so much a review as a response to those who feel this is just a list of Tcodes and doesn't provide much other useful information. In point of fact you could just run SE93 and install a tool like RBE to get a complete (humongous) list of TCodes and frequency of usage. The point of a book like this is to provide a starting point standard transactions grouped by module/functional area. The descriptive title SAP provides is occasionally cryptic - and often "Germish" (an English/German hybrid) - but with this book you have a starting point to find transactions to test. No one who is a serious user of SAP should ever take a TCode and just blithely run it thinking they know what it's going to do, without first checking it out. This is just a starting point. Going through folders of menus is time consuming and wont list all the transactions that are available. Sometimes the new "N" version of TCode doesn't have the functionality that the old one had. So is this a book like this the greatest thing since sliced bread? No. Will it tell you exactly how to configure an area, create master data, make transactions, correct errors? Absolutely not. But if you are willing to hack about a bit and try different transactions, this could make a good starting point for you. Bear in mind that your friendly local ABAP programming group has probably been busy putting in custom programs with custom TCodes, so make sure to run SE93 for all Z* or Y* transactions to see how YOUR system has been locally customized. It's a rare shop that has no custom Tcodes. So how good is this book, use it for what it for, and pick up others for more in depth treatments. Caveat Emptor - make sure you check out the any technical books before you buy. Amazon's "look inside" feature should give you a good idea if the content is solid and concise, or a random philosophical walk with no real content to tell you how to actually "do it" (and why).
