How do I quickly and easily view total amount of a given customer's booked orders?

I'm pretty new to OM so forgive me if this is a dumb question.

My users want an easy way to view total dollar amount of Booked orders.  The way I'm currently doing this is to pull up the customer's orders in Order Organizer, then Export to Excel where I sort and subtotal by Status to get the total of Booked orders.  Is there a way to view this data in Oracle?  Or even a report?

Thanks,
