Product schedules are features that allow administrators to track revenue or quantity over time for products in opportunities or orders. Product schedules can be either revenue schedules or quantity schedules, depending on whether the product is sold by amount or by quantity. Product schedules can be either standard or customizable, depending on whether they use predefined settings or custom settings.
Line item schedules are records that represent each installment of revenue or quantity for a product over time. Line item schedules are created automatically when a product with a product schedule is added to an opportunity line item or an order product.
One limitation of product schedules is that line item schedules are unavailable in Process Builder and Workflow. This means that administrators cannot use these tools to automate actions based on line item schedules, such as sending email alerts, creating tasks, updating fields, or invoking flows.
