Year Ago Measure group by problem.

Question

Hi,
In my report I have two measures Revenue and Revenue Year Ago.
Revenue Year ago is calculated based on the Ago functionalty and the time dimension level is "Year"
AGO(Fact.Revenue, TimeDimnesion."Year", 1).
The problem is that the column measure Revenue Year Ago is not getting added up to display data when we select based on the time dimension.
e.g.
Dimnesion Month-Code Revenue Revenue Year Ago
A Jan-10 100 90
A Feb-10 200 160
B Feb-10 250 200
In my report I want to display the Dimension, Revenue and Revenue Year Ago for the month of 'Jan-10' and 'Feb-10'
so that automatic group by happens for the measures like this.
Dimnesion Revenue Revenue Year Ago
A 300 250
B 250 200
But this is not happening when I apply the filter for Month-Code in ('Jan-10' and 'Feb-10') and the result what OBIEE gives is null value for Revenue Year Ago.
Dimnesion Revenue Revenue Year Ago
A 300 NULL
B 250 200
But when I remove the Month-Code filter it gives the correct result.
So is there something that I am missing out. Please advice.
TimeDimnesion Hierarchy is Total(Grand Total) -> Year (Year Id, Year Code) -> Qtr (Qtr Id, Qtr code) -> Month
(Month-Id,Month-Code) -> Detail (Day-Id, Day-Code)

Answer 1

if you can give a small test case to play around, it
might be helpfule.
put the data in the table and show the output you
desire.An example-
STORE
StoreID StoreName Location
s1 ABC NY
s2 XYZ LA
PRODUCT
ProdID ProdName
p1 foo
p2 moo
TRANSACTION
TransID Fiscal_Yr StoreID ProdID Rating Price
t1 2002 s1 p1 A 10
t2 2002 s1 p1 A 80
t3 2002 s1 p2 A 15
t4 2002 s1 p1 B 20
t5 2003 s2 p1 B 50
If the query below is executed-
SELECT t.Fiscal_Yr, s.StoreName, p.ProdName, t.Rating, SUM(t.Price) Revenue
FROM STORE s, PRODUCT p, TRANSACTION t
WHERE s.StoreID = t.StoreID
AND p.ProdID = t.ProdID
GROUP BY t.Fiscal_Yr, s.StoreName, p.ProdName, t.Rating
ORDER BY t.Fiscal_Yr, Revenue DESC
then, we get
Fiscal_Yr StoreName ProdName Rating Revenue
2002 s1 foo A 90
2002 s1 foo B 20
2002 s1 moo A 15
2003 s2 foo B 50
But, irrespective of different ratings for the same product, the revenue should be added and I should get rating as listed in the first transaction for that product for a particular store and Fiscal_Yr. So, my desired result should be-
Fiscal_Yr StoreName ProdName Rating Revenue
2002 s1 foo A 110
2002 s1 moo A 15
2003 s2 foo B 50
