The Inventory Value Report shows the current value of Inventory Items by Inventory Location. The Inventory Value report doesn’t include Items with an Inventory Type of Non-Stock, Service or Consignment. A Negative Extended Cost would mean the Quantity on Hand for that particular product is below zero.
If your facility has negative Quantity on Hands for some products, we recommend doing a Physical Count for those items so you can see the “true” value of your inventory.
