When you have a parent and a child database you can run reports on both locations by heading into the Corporate admin section and running the Corporate reports.
First start by clicking the Corporate Admin link.
Next you will find the Reports section and click on Corporate Reports Home.
You will then see your options for the Corporate call center report , the Corporate detailed marketing and detailed sales reports.
These are customizable reports that you can then use to build the reports you need to report on all of your locations.
