Cartesian Product in BI Reports

Question

Hi Experts,
I have following tables
Dim: Population table
Year, Gender, Age Range, Population
2008 MALE <1 100
2008 MALE 1-20 300
2008 MALE 20+ 500
And, Fact Employee table
Employee Id, Year joined, Gender, Age range
120 2008 MALE 20+
121 2008 MALE 20+
122 2008 MALE 1-20+
123 2008 MALE 1-20+
Now, when i joined my Dim and fact across year,gender, age range. (But franly, speaking it is some thing N:N rather than 1:N)
And, when i tried to create report as Year joined, year, Population , total no. of employees
Each Year joined column in fact is multiplied across dim (instead of only one year - which is resulting in cartesian)
How to avoid.. this one ?
I knew, how to resolve this issue on answers. But, it should be done dynamically.

Answer 1

Since you know how to fix this using Answers; I would suggest fix it in answers->run the report-> get the BI generated Physical SQL query. Study the Physical SQL query and try to put it in RPD.
That would be the easiest way to do.
Mark if helps :)
