[development-axapta] Need some help with getting data about sales orders that have already shipped.

[Sean Miller]

I'm working on a report that will compare the Requested Ship Date to 
the actual ship date for sales orders.
I know where to get the Requested Ship Date, but I can't seem to figure 
out where to find the date that an order was actually shipped.
Anyone know which table I need to look in to find this?
How do I determine whether a sales order line has already been shipped 
or not?
