Reports are automatically saved against the client(s) they have been created for, and can be accessed at any time by clicking write / view report from the main dashboard. To view the reports belonging to a client, search for the client using the client search and add them to the Selected Client(s) List.
You can then access the client's report library by clicking on the view reports link to the right. The number in brackets to the right of the view reports link indicates how many reports are saved within that client's report library. On clicking the link, you'll be directed to that client's Report Library. To view / edit / download the report click the report builder link for that report.
