Field for product Shelf Life
It doesn't appear there is a field or table column for 'shelf life' in the product manager. it would be great if there was a field so we can more easily maintain our more perishable inventory.
CMS does have two user-defined fields for products that may fit the bill. See my example here - http://screencast.com/t/ybZ8Dc0kLAF
On a related note, CMS also allows you to set an expiration date on inventory lots during the receiving of purchase orders. See - http://screencast.com/t/uGJySAeymxKD
Noting this expiration date field is not currently available in Stock Manager to be set for inventory received manually (not through Purchasing). That would seem to be a reasonable enhancement for us to make if it was needed.
