The document discusses scheduling in Convergent Invoicing (CI) or BRIM. It explains that scheduling helps determine the target date for billing billable items and distribute the system load. Billing cycles can influence the target billing and invoicing dates. Regardless of billing cycles, dates can be adjusted using grace periods, periods, or custom calendars. Three examples are provided to illustrate how the system determines target dates for billable items created on different dates based on the configuration.
