From Char Gust of Microsoft via the Dynamics GP Newsgroup, here's some reporting hints for Dynamics GP 10 due early next year:
"With Dynamics GP 10, we will be adding several new options for getting data out of the system, including pre-defined refreshable Excel reports and about 100 SQL Reporting Services reports. We have prioritized the reports that are highly used, often customized. We hope these new reporting options will alleviate some of the concerns noted here. "
