Hello Nayan,
It should have only one level. This is a sample data. The Level 2 should not exist. The other records have already data and are ok. Let say we have Pallets on the floor in a warehouse. One Station has two Rows and fortheen positions deep.
Look into this web site for an example:
http://palletsincorporated.com/Products/products.htm
<pre lang="css">Lgvcs.StationPositions
