Reporting Periods

A reporting period defines a time range with a start and end date. The start date and end date do not have to match with billing periods defined by external billing system. Reporting period is the smallest time interval for hierarchy versioning. In other words, changes made to hierarchies within a period will not be tracked or versioned. Only the changes made across different periods will be versioned.
