This is the list of all the production lots you recorded. When you select a lot, you can get the traceability of the products contained in lot. By default, the list is filtered on the serial numbers that are available in your warehouse but you can uncheck the 'Available' button to get all the lots you produced, received or delivered to customers.

Click to add a reordering rule.

You can define your minimum stock rules, so that OpenERP will automatically create draft manufacturing orders or request for quotations according to the stock level. Once the virtual stock of a product (= stock on hand minus all confirmed orders and reservations) is below the minimum quantity, OpenERP will generate a procurement request to increase the stock up to the maximum quantity.
