=====Why do I have negative inventory showing on my reports?=====
On certain reports, CATS will show negative inventory or open units or weight. In this wiki page, we will discuss the causes of this negative inventory and how to fix them.

====What Causes Negative Inventory?====
  - **Overbought/Oversold Items** - If you have more units and/or weight on the invoice than is on the contract item, CATS will show negative inventory.
  - **Allocation of Items with Differing Bag Weights** - If you have allocated a sale item with more weight than is on the purchase item, then you will see negative inventory in CATS.
