@al3xicon - we've experienced ghost inventory top. they appear on certain searches and, in my experience, have been caused by mis-matched lot codes and/or related to some timing issue. What I've done previously is hide the (truly zero-inventory valuation / zero qty really in the system and zero qty on-hand) results using a custom field + criteria.... and then contacted NetSuite so they can figure it out and help remove the item from results.
