You create time periods with detail required by financial models. You can combine periods of years, weeks, months, quarters, and halves for historical and forecast data. You can create period-to-date periods, trailing periods, and, for transactions reporting, deal periods and subperiods.
The Time Periods dialog box enables editing time period structure and settings. You can select last historical periods, add or delete periods, change time details, change period labels, select periods to display, and insert periods-to-date or subperiods.
