The first recommendation I would make is invest $2500 in yourself and send yourself to live training with a reputable education partner for Crystal Reports. Their material is the best on the market and the Education Partner's Instructor usually brings life experiences to the classroom. You learn, experiment and cement how Crystal works. I would recommend taking the first 2 classes (4 days) one month, wait two months and then take the third class.
Second there is a book, not an XI book but a good book by Annette Harper - "All In One CRCP" that should be in everyone's library.
Third the book you mention is a good tool, but I would suggest Annette's first, then that one.
I have read or reviewed almost every CR book out there and both of these books are good, but Annette's is best. And that is my humble opionion.
Thanks so much!
