          You can determine the periodicity of the data to be displayed in Demand Planning Workbench, using the  option. The data is displayed in the associated buckets based on the selected periodicity. These are the available periodicities:
         
         - All
 - Years
 - Quarters
 - Months
 - Weeks
 - PWeeks
 - Days
 - CAll
 - CYears
 - CQuarters
 - CMonths
 
The available periodicity, forecast, and history horizons are defined on the System Settings screen. The periodicity used by default, is set on the System Settings screen. The data displayed in Demand Planning Workbench is based on the selected periodicity. For example:
- If a calendar periodicity is selected (for example, CYears), data is displayed based on the Gregorian calendar.
 - If a non-calendar periodicity is selected (for example, Years), data is displayed based on the system calendar as defined in the initialization wizard.
