# Stock Lot Shelf Life Expiration Date

The stock_lot_sled module adds two fields on lot of products:

> - Shelf Live Expiration Date

> - Expiration Date

And it defines on the product the default time for those fields and on the stock configuration the Shelf Live Delay.

When the shelf life of a lot expires in less than the configured shelf life delay, it is no more used to compute the forecast quantity of the stock.
