All Planning and Consolidation reports and input schedules use custom functions to retrieve, send, and display data. These functions are commands that are used with cell references and values in formulas to make a report behave in a certain way, providing power and flexibility to reports and input schedules.
You can insert functions into reports and input schedules to build formulas. You use the formulas to create or modify reports and input schedules.
You use the Insert function option on the action pane to insert functions.
