When you order items from the supplier, you can specify the parameters that determine the monitoring thereof, or the dice before the order or upon receipt (you probably know these caracteristics when receiving physical goods).
Once the supplier order is complete, the monitoring parameters are registered and assigned to items in their warehouses.
You can also enter the monitoring criteria such as you have configured in various entries, or, in the corrections of stock.
On the disposal of the item, you can select the batch to which it belongs, or in the customer order, either in an other outgoing, or in a correction of the stock (inventory update).
