Use to specify a lead or lag time to a period-to-date of the same type. This function enables you to create formulas where you want the period-to-date periods to lag a full period instead of using the value from the previous period.


Assume you define a formula using Oct09:YTD in which the value (V1000) from the previous year, 2008, is used V1000( -1 ). To use a value other than the 2008 period-to-date result, use V1000( @likepd(-1)).
