Aggregating from different level

Mon, 28 Dec 2015 12:47:34 GMT

Hi all,

I have an issue with a Sum of diferent values for a dimension that is a lower level respect fact table.

My fact table don't include a dimension that I need for work with:

FACT TABLE
Id_Person	Age	Gender	Affected
1	3	Male	1
2	1	Female	1
3	14	Male	1
4	33	Male	1
5	20	Female	1
6	45	Male	1
7	67	Male	1
8	74	Female	1

Dimension:

DIMENSION TABLE
Dimension	Sum (Affected)	Condition
Dim1	3	<15
Dim2	2	>15 & Female
Dim3	2	>65
Dim4	8	ALL
Dim5	8	ALL
…	…	…
Total	8

Although 'Dimension' is not included in Fact Table, it is possible work with it joining this dimension by different conditions like Age and Gender. I need obtain something like this, but additionally I need work with multiple values for this dimension:

Expressions
Selected Dimension	Sum(Affected)
Dim1;Dim2	5
Dim2;Dim3	3
Dim1;Dim2;Dim3	6
Dim1;Dim2;Dim4	8
Nothing in Selector	8

I try to get this result:

Expedted
Dimension	Cost	Affected people
Total	6000	8
Dim1	1000	3
Dim2	1000	2
Dim3	2000	2
Dim4	1500	8
Dim5	500	8

with a Set Analisys like:

Sum({<$(PARAM Excluded Dimensions) >} $(PARAM Conditions) FT_AFFECTED_PEOPLE))

where:

$(PARAM Excluded Dimensions) are Dimensions including 'Dimension'. I need this clause for obteining the correct value.

$(PARAM Conditions) is a CASE expression that add filtering condition for fact.

FT_AFFECTED_PEOPLE is a simple registrer count from Fact Table.

With this solution I can obtain the Total Count of affected people but don't get the value of each dimension:

Solution1
Dimension	Cost	Affected people
Total	6000	8
Dim1	1000	0
Dim2	1000	0
Dim3	2000	0
Dim4	1500	0
Dim5	500	0

This solution works fine for a text box with a totalizer, but in a Pivot Table with 'Dimension' is not a fine solution.

Other solution that I tried are Aggregator by 'Dimension' and modify script for get a field with a value for each value of 'Dimension', but I can't get a correct solution.

What can I do for get correct solution avoiding cross join between Dimension and Fact Table?

Thank you in advance.

Perhaps the attached example helps. If not, please explain why.

Many thaks Gysbert!

It is not a perfect solution, because Totals do not work correctly, but for me it is fine.

Now, I have a problem with my data because Fact Table is concatenating some local tables and expression don't work fine because a table has checked dimension. Anyway, it's another issue.
