How can a report of all Accounts with Opportunities be created?

 Using the Accounts with Opportunities report type is the best way to create a report of all Accounts with Opportunities. A report type defines the set of records and fields available to a report based on the relationships between a primary object and its related objects. The Accounts with Opportunities report type includes accounts that have at least one related opportunity, and allows fields from both objects to be displayed in the report. Using the Accounts report type would not work, because it would include accounts that do not have any related opportunities. Using the Opportunities report type would not work, because it would not include account fields in the report.
