all item fulfilments where status = shipped?

For some reason, we don't want our third party warehouse manager to edit the IF. That's why, the accounting team creates the IF then the warehouse manager then prints the shipping label to actually ship the orders. Management doesn't want to change the business process so I'm stuck.

Wouldn't it be any fulfillment that has tracking numbers? In theory someone could hand key in a tracking number although that seems much less likely with the shipping integration enabled. Type=Fulfillment & Tracking Numbers is not empty seems like it would get you there, but I've not validated.

Thanks but I don't think that would work for us. Our inefficient process is Accounting generates the IF, the warehouse actually ships the items based on IFs. So an IF does not actually represent an actually shipped item, sometimes it is shipped the next day.
