I've been recently looking into ways of tracking changes of consumables such as Printer Toners, and also Company Resources.
I would like to see a Consumables Option within SDP to track stock levels of a consumable. For example when a Toner is changed, I'd like to assign the Toner to the relevant Printer asset. Then when stock is running low, an automated e-mail sent to the person who procures the Printer consumables.
