Hi Alexandra,
If you want to remove paper from the picking process, you need some other way to assign Work to the user's scanner.
Another would be to use mobile device menu items configured to do
System directed work processing.
But you still have the problem that when the items arrive at the packing area, the packer needs to know which shipment they are for. To solve this, you can use the Target License plate Id. You may need to adjust your picking process slightly to accommodate. One way to do it is to give your pickers pre-printed 'license plate' labels. And you need to configure the picking flow to ask for a Target license plate Id.
At the start of the picking process, the user will be asked to scan the Target LP Id. They reach for a pre-printed label, scan it, and stick the label on to the item they have picked (or onto whatever they using to carry the items they have picked to the packing area - for example, onto the pallet or trolley or whatever it is they are using).
At the packing area, you'll notice that the Pack screen asks for a 'License plate or shipment'. The packer scans the LP label for the items, and the Pack screen will find the shipment it belongs to, and then the packing process will proceed as normal.
For shipments which are Picked but not Packed, you could look at Shipment status.
Waved means work has been created but not started.
Assuming your Container packing policy has the Container release policy field set to Make available at final shipping location, a Loaded shipment is one where all items have been packed into containers and the containers are Closed.
Meaning your In progress Shipments might be the one's you are interested in.
Or for another approach, at Warehouse management > Setup > Packing > Packing station setup, make sure you have Create packing work enabled for all your packing locations. Then, when you look at the Work details screen, you can see any Open or In progress work with Work order type = Sales order or Packing, and you can see the Shipment Ids.
And if you are looking around a packing area and you can see some unpacked License plates, you can filter the Work details screen by Target license plate Id to see which Shipment the License plate belongs to.
