If you have ever thought to yourself, "Gee, I sure wish I had a list of all the reports in my AX installation," then your wait is over.
Now you can use this handy report to generate a list all of the reports in your AX 2009 installation. After you import the XPO, you'll see a project called BookOfReportsV1. Within this project there's a report called BookOfReports and an output menu item called BookOfReports.
To run the report, just right-click on the report and select Open.
Many thanks to Jose Lorenzo at Microsoft for providing this code.
