How to merge two MDX query results having different measures and filters? - ssas

Question

Let's start by saying that I'm a total newbie on MDX, I need to merge two (or more) query results into one pivot.
The queries will have the same dimensions on ROWS and COLUMNS, but different measures and filters (normally a time period).
Here is an example
Query 1:
SELECT
NON EMPTY {{[stores].[storecountry].[storecountry].Members}} ON COLUMNS,
NON EMPTY {{[SalesTypes].[Description].[Description].Members}} *
{[Measures].[TransactionValue], [Measures].[TransQty]} ON ROWS
FROM [Model]
WHERE ({[dDates].[Date].[Date].&[2016-01-05T00:00:00] : [dDates].[Date].[Date].&[2016-01-12T00:00:00]})
Result of query 1:
CA US
Regular Sale TransactionValue 761 16
Regular Sale TransQty 8 233
Return TransactionValue 156 4
Return TransQty 1 45
Query 2:
SELECT
NON EMPTY {{[stores].[storecountry].[storecountry].Members}} ON COLUMNS,
NON EMPTY {{[SalesTypes].[Description].[Description].Members}} *
{[Measures].[DiscountPerc]} ON ROWS
FROM [Model]
WHERE ({[dDates].[Date].[Date].&[2015-03-12T00:00:00] : [dDates].[Date].[Date].&[2015-06-02T00:00:00]})
Result of query 2:
CA US
Regular Sale DiscountPerc 40 % 59 %
Return DiscountPerc 32 % 43 %
Expected result after merging
CA US
Regular Sale TransactionValue 761 16
Regular Sale TransQty 8 233
Regular Sale DiscountPerc 40 % 59 %
Return TransactionValue 156 4
Return TransQty 1 45
Return DiscountPerc 32 % 43 %
Is it achievable without manually merging the AdomdClient.CellSet from the calling application?
Thank you!

Answer 1

I'd use calculated members:
with
Member [Measures].[TransactionValueReport] as
Aggregate(
{[dDates].[Date].[Date].&[2016-01-05T00:00:00]:[dDates].[Date].[Date].&[2016-01-12T00:00:00]},
[Measures].[TransactionValue]
)
Member [Measures].[TransQtyReport] as
Aggregate(
{[dDates].[Date].[Date].&[2016-01-05T00:00:00]:[dDates].[Date].[Date].&[2016-01-12T00:00:00]},
[Measures].[TransQty]
)
Member [Measures].[DiscountPercReport] as
Aggregate(
{[dDates].[Date].[Date].&[2015-03-12T00:00:00]:[dDates].[Date].[Date].&[2015-06-02T00:00:00]},
[Measures].[DiscountPerc]
)
Select
Non Empty [stores].[storecountry].[storecountry].Members on 0,
Non Empty [SalesTypes].[Description].[Description].Members * {[Measures].[TransactionValueReport],[Measures].[TransQtyReport],[Measures].[DiscountPercReport]} on 1
From [Model]
