We miss the ability to search for a product in all orders, not just active orders (Inbound stock). If we, for example, have a customer complain on a product and we need to contact our supplier about it, they want to know the order information. Now we manually have to check though all orders to see when and how it was ordered. A search for products in all orders would be really be helpful - in many other ways too.
Atum staff suggested that we should use Multi-Inventory batch tracking functionality, but we had some performance issues with Mutli and don't want to use it. We are just fine with PO Pro and to search for a product among all orders seems like a basic thing for any order system.
