Threshold feature guarantees a minimum number of units of the assets in the inventory always. Whenever the actual number of units of the category assets drops below this threshold value system will notify. Inventory keepers must know how long it takes to receive orders and how many units will sell in a period of time to determine the correct value for setting the alert.
Go to the CONFIG > Threshold > Edit Threshold. Value of Threshold can be managed here.
Go to the Send alert to > As per general settings.
