As an outsider, I'm confused over how little detail means you can't do anything. If you have the store number and the date, you have the truck(s) that went to that store. You have the trucks, so you have the items on the truck. You have a list of items, you can match it to the items or pictures of items to narrow down further. Then with the list and the items on the list highlighted, you can find who was on shift the day and time the truck was packed, so you can narrow further to who touched what items.
Is it that you need a lot of detail, or it's too much of a pain to take the steps to find out who was hands on that truck?
