Alternative to IF Historical Period? formulas
It seems like almost every model I've taken over has relied heavily on something to the effect of:
IF Historical Period? THEN Actuals ELSE Forecast
I've seen some really **** formulas that have separate business logic for historical and forecast periods nested within the two conditions. Generally, this issue is easy enough to simplify by breaking out the business logic into multiple line items then applying the historical IF/THEN in one line item.
The thing I've had trouble simplifying with this type of formula is historical overrides. Essentially you need to add something else that checks for overrides before the historical period such as:
IF Override? THEN Override Value ELSE IF Historical Period? THEN Actuals ELSE Forecast
This can get overly complicated pretty quickly when you have to add in other business logic.
I'm wondering it there is a better way to approach using Actuals/Snapshots in historical periods than using an IF/THEN statement like above?
