Hi,
Yes it is possible to ship and receive the same license plate. As you shared that one license plate is one item can you confirm if one license plate contains multiple qty of same item or just one qty per license plate.
Below is an example of shipping and receiving same license plate for serialized item when one license plate is 1 qty.
1 - On hand for an item as below
2 - Create a transfer order. In cases where one license plate is one item and one qty make sure you keep packing qty as 1.
3 - In the work templates make sure you flag the 'Packing qty as max" check mark
4 - Release the transfer order to warehouse and you will get two works one for each license plate. As one license plate in this case is one item and one qty.
5 - Start picking on mobile device by scanning original license plate
6 - Ship transfer order so that its status changes to Shipped
7 - Receive original license plates in receiving warehouse.
Let me know if you store multiple qty of same item one same license plate where they all have a unique serial number.
