This alert will deliver a stack-ranked list of parts and supplies used most often which are missing yield data. It will also show you all parts and supply items created in the last thirty days missing yield data. The list will include the 'top ten' most used items, and then all items created in the last thirty days. If an item is not meant to have a yield (for instance, a circuit board) set the yield = 2 so that it will not trigger any of our processes (including this one). Use this with alert ID90, parts below yield.
