Dealing with "committed" inventory

Does anyone have parts inventory for sale that also deals with this confusing "committed" inventory column?  Can we shut down committed because it just seems to cause more confusion than for little benfit it gives?

Or, how do we deal with this committed column? It's so puzzling as we'll show e.g. 500 on hand, but have a backorder of 12 that ends up in committtted (along with other non invoiced sales orders) thanks for any guidance
