Adopt database change in Crystal Reports

Problem

After I add/update fields in the database, the change is not adopted by "Database Fields" in the Field Explorer panel.  

Solution

Go to "Database" menu item and click "Verify Database" to refresh the database. This solution works with Crystal Reports 2008.
