What does the "Remove Zero Quantity Costing Tiers" utility actually do?  I believe it removes any tier in the ItemCost file that has a quantity on hand of zero and a date prior to or equal to the date chosen in the utility BUT does this remove the ability to find out what happened to a particular lot?  If I run this utility, can I still find out what customers received a particular lot of product?

Thank you,
