Year ago Calculation along with Current Year Calculation

[Cognos10x]

Hi Guys, I am really stuck at revenue calculations for Year ago. When the user select a range of calender dates for instance Mar 1 2009 to Mar 31 2010. He wants to see revenue for that time period and also Previous years calculations ie. Mar1 2008 to Mar 31 2009.

I tried _add_years(?calender_date?,-1) with if and case statements but I am not getting Year ago calculations, but I get 0.  Do you have any thoughts about this ?

Hey,
I am not sure if this is the best way, but how we do it in our environment is as follows:
- Do not filter the query by the date range (this is important!) - the filters should be embedded in the calculation:
- You will need to define 2 metrics:
1. Selected Date Revenue:
IF (date between ?startdate? and ?enddate?)
THEN (revenue)
ELSE (0)
2. Selected Date Prev Year Revenue:
IF (date between _add_years(?startdate?,-1) and _add_years(?enddate?,-1))
THEN (revenue)
ELSE (0)
**assuming you have two prompts for start and end date
You can then do year over year growth...etc.

I Tried this by just putting in the calculation rather than in filters for prompts but I am getting 0 even for current select
