Inventory items can be set to notify for re-order when a minimum of that item is reached. Items are kept at various locations, but the minimum amount for re-order applies to the total amount of that item in the system. It does not notify if a particular location needs re-stocked. Please make the minimums per stock location rather than per inventory item. Currently, I have to make a different item entry for each building in order for re-order notification to be useful.
