Summary:

Need to be able to set 'minimum shelf life days' for onhand lots pegging to demands.

It is a common practice in medical device companies to ship only the material that has atleast x amount of shelf life left. some times it is also dependent on the demand type. Demand from Distributors must use lots that have atleast 2 years of shelf life versus demand from end customers (that should have minimum of 6 months of shelf life left). With that said, it becomes important for supply planning engine (unconstrained or constrained) to consider it while planning supplies. An org-item level and demand class level attribute combined with planning engine might be useful to satisfy this
