it's impossible to answer without seeing the data Ed. Inventory is complicated...
basically, (IMO), a good inventory setup IS going to have a transactions table. or 2, or maybe even 3 of them. if inventory goes out, you should always record it, regardless of where you put it. if you have the right fields then in the ''recording'' table, you can easily write the following to see how much of a certain product went out any given week:
Code:
select productname, sum([quantityfield])
from table
group by productname
having [productname] = "criteria section" and datefield between #startdate# and #enddate#
