This is the most expensive SAP book on the market, and I can't understand why, except perhaps because it is the only one covering FI decently. There's no content on CO, and it's based on an old version of SAP. Nevertheless, it provides some helpful insights. But the price is outrageous and not justified--on what basis does it rate as the most expensive SAP book on the market? The publisher should stop gouging and start discounting, since the book's worth is just like yesterday's paper, good for a few days and in special cases, but worthless to many, to be superceded by newer entries (unless it is destined to be a classic, which it ain't). Buy under protest!!
