The Product Active switch determines whether a product is available for the picking process or not. For example, seasonal products, raw materials or other goods that are not currently to be sent out can be deactivated. In this case, the storage is still occupied, but the products cannot be released for picking.
Please note that the switch has no direct connection to the settings in your online shop, but only affects the handling in the warehouse. In order to avoid error messages when releasing the shipments for fulfillment, please make sure that all products for sale in your shop are set to active.
