[AccessD] Inventory Question

I am doing a donation in and out database for a local food charity as my
Katrina help.
 
Inventory comes in on pallets. It is then broken down to boxes and units per
box. Boxes * units per box = indiv items.
 
Why am I keeping track of pallets if they do not effect  inventory count?
