BusinessObjects has been great and fairly easy for me to use, but I have had problems understanding how to put formulas in my reports. In this book is a great chapter on how to use formulas. It is very thorough and easy to understand. At first I just looked up the formulas that were in reports that were created for me. Now that I understand how to use them I am able to put formulas in reports myself. The rest of the book seems pretty good, but I have to admit that I have not had time to really look at the rest.
