Plan item breakdowns The total cost in a budget plan is divided into smaller units called breakdowns. The breakdowns are taken from the Unit Cost in Local Currency field of the plan item. After the plan is promoted to a forecast, these values are used to calculate the value in the forecast's Amount field. You can override this amount in the plan item breakdown record with a new amount of your own. The application automatically calculates plan item breakdowns when you save the plan item. Note: Plan item breakdowns support all fiscal calendar types. See Fiscal calendars for more information.
