Это ответ метода. Я хочу выяснить, что означает approved_items.quantity. По предположению это delta, на которую я могу увеличить текущее кол-во товара в поставке, но практичным путем выяснил, что это не так. Я смогу увеличить кол-во товара, только если approved_items.quantity >= approved_items.origin_quantity?
