Our company has a lot of warehouses with a lot of inventory. An example of a location would be A01A1, A01A2, A01A3, A01A4 where A01 would be a floor space and inventory would be stacked 4 high on top of each other. My question is what if A01A3 gets left out during inventory count? How can I query to find these missing locations? Hope this makes sense. Thank you.
