The Inventory > Order tab does show a list of all ORDERS so you can see how many orders were placed and see the bottom line totals in the grid's footer. However, I think I understand what you're really asking for here is to see a list of the ITEMS on all of the orders.
We can use the SQL Workbench to get a list of the Items. Copy and paste the following SQL statement and run it:
--------------------
select Item_Number, Description, sum(Qty_Ordered) as Quantity from Item where Order_ID in (select Order_ID from Order where Order_Date between '2012-9-1' and '2013-5-1') Group by Item_Number
--------------------
Note: Since you wanted to see all the ITEMS order LAST YEAR, I used an example date range of 9/1/2012 to 5/1/2013, if your starting and ending dates are different you can adjust accordingly, but you have to keep the date format of 'yyyy/mm/dd' as shown above.
Note: The Quantity column is the Order Quantity and therefore does not take into account Package Quantity, but this should be ok as long as you are aware of it.
