We can either...
1. Delete an order and move packaged items (new IDs) back to inventory
Option 1: Delete an order without un-packing (keep IDs)
To delete an entire order and keep all converted IDs, go to Edit > Delete Order:
Now, all New IDs are still packaged and available on the Inventory page!
Option 2: Delete the order after un-packing weight back to the parent
If we don't want to keep the converted IDs, we'll un-convert our packaged item and then delete the order.
1. Go to Delete > Un-Convert (or Un-Pack):
2. Now go to Edit > Delete Order:
Now your weight is returned to your parent lot and is available for use on the inventory page!
