Need Data Modeling help

 

Hi All,

 

I have a scenario based question.

 

Fact 1

Measure Column A, Column B (Dimensional data point), FK_Dim1, FK_Dim2, Column M

 

Fact 2

Measure Column C, Column F(Dimensional Data point) , FK_Dim1, FK_Dim2

 

Dim 1

Column D (Category)

 

Dim 2

Column E

 

I want to create a detail report with the following

Column D, Column E, Column B, Column F

 

Now Column B should display data only for a particular category present in Column D (e.g. Headcount). So when my Category is Headcount , column B is applicable. 

And when Category is Attrition, Column F should display data and Column B should be null.

 

Any help in modeling this scenario would be appreciated.

 

Note: I have gone through this video but this dint help.

Just to add, I want to avoid creating a Union query or Merging both the Fact as this is just a sample of my requirement. Ideally I need similar logic with 5-6 Facts. And each Fact has different set of columns.

 

 

Regards,

Akash

    For your requirement, I think you can only create a calculated column in each Fact table with SWITCH() function to assign BLANK() based on Category column values.
