Is an input period

A relative reference in @if statements.

Use in time period structures containing aggregate or year-end periods: months, quarters, halves. Use this function with accounts convertible into calculated accounts: memo accounts, ratio accounts, and covenant accounts.


  • True—if the period is an input period

  • False—if not


If 2006 is in quarters with an aggregate year end, this formula:

@if(@isinput, 1, 2)

returns 1 for each quarter of 2006, and 2 in the year end 2006.
