This app is only available in the Enterprise and Cloud Editions.
This app implements planning capabilities for items with a limited shelf life. These items go to waste when they are kept too long in inventory, and thus create an challenge for planners.
The app extends the data model with extra fields to store the shelf life of items, the expiry date of inventory, scrap orders and the required shelf life for demands.
The app highlights situations to the planner where inventory is expected to expire. It can also automatically generate scrap orders or propose other actions to resolve waste situations.
See this example for a detailed example of these features.
