When you try to close the container in the WHS packing form, you receive the following error message:
"License Plate already exists in another location.
Update has been canceled.
Container XXX did not close."
Microsoft has evaluated this issue, and will not be issuing a fix at this time.
The work around is when more than one line exists that has the same license plate (LP) in the same container, you can apply a container ID which is different from one of the LP IDs in the container.
