We started writing "SAP BW: A Step-by-Step Guide" in 2000. At the beginning, it was only for fun, trying to find something to do in hotel after a long day on project. Addison-Wesley published the book in 2002. Since then, we have been excited about the warm response and constructive feedback from the SAP community. Now we are an SAP partner and will have the software to upgrade the book to the latest release. Thank you all for the patience.

With the good experience, we decided to write another book on application of Service Level Management (SLM) to ERP project management. This time we will write in Chinese first. We see the urgency to improve the success rate of ERP implementations in China.
