ssas calculated member with several member properties - ssas

Question

I'm wondering if there's any better way in writing a calculated member like this:
(
[Measures].[Number of accounts]
,[Account Status].[Account Status].&[Anonymous]
,[Account Status].[Account Status].&[Closed]
,[Account Status].[Account Status].&[Closed due to Fraud]
,[Account Status].[Account Status].&[To be closed]
,[Account Status].[Account Status].&[<unknown>]
)

Answer 1

This is a tuple - and a very efficient way of locating a part of the cube:
(
[Measures].[Number of accounts]
,[Account Status].[Account Status].&[Anonymous]
,[Account Status].[Account Status].&[Closed]
,[Account Status].[Account Status].&[Closed due to Fraud]
,[Account Status].[Account Status].&[To be closed]
,[Account Status].[Account Status].&[<unknown>]
)
...BUT it needs to be a specific point in the cube - but you've included several members from the same hierarchy [Account Status].[Account Status] so this is not a single point in your cube and it will therefore error.
Here is an example of a valid tuple:
WITH
MEMBER [exampleTuple] AS
(
[Measures].[Internet Sales Amount]
,[Date].[Calendar Year].&[2007]
)
SELECT
[exampleTuple] ON 0
,{
[Product].[Category].[Bikes]
,[Product].[Category].[Clothing]
} ON 1
FROM [Adventure Works];
So this gives back internet sales but only for the year 2007:
If I do what you've done and add say another member from the year hierarchy into the tuple then it gets confused as unsure which bit of the cube I'me referring to - 2006 or 2007!
WITH
MEMBER [exampleTuple] AS
(
[Measures].[Internet Sales Amount]
,[Date].[Calendar Year].&[2007]
,[Date].[Calendar Year].&[2006]
)
SELECT
[exampleTuple] ON 0
,{
[Product].[Category].[Bikes]
,[Product].[Category].[Clothing]
} ON 1
FROM [Adventure Works];
gives:
double-clicking on the word #Error tells us the exception:
Exactly the exception we'd expect.
A way around this exception is to pre-aggregate the members from the same hierarchy into a single member so the processor knows exactly which part of the cube space to go to:
WITH
MEMBER [Date].[Calendar Year].[All].[2006+2007] AS
Aggregate({[Date].[Calendar Year].&[2007],[Date].[Calendar Year].&[2006]})
MEMBER [exampleTuple] AS
(
[Measures].[Internet Sales Amount]
,[Date].[Calendar Year].[All].[2006+2007]
)
SELECT
[exampleTuple] ON 0
,{
[Product].[Category].[Bikes]
,[Product].[Category].[Clothing]
} ON 1
FROM [Adventure Works];
Now we get what we want:
We can then use this initial aggregation to do whatever we want - you mention excluding some member - this is possible:
WITH
MEMBER [Date].[Calendar Year].[All].[2006+2007] AS
Aggregate
(
Except
(
[Date].[Calendar Year].[Calendar Year].MEMBERS
,{
[Date].[Calendar Year].&[2007]
,[Date].[Calendar Year].&[2006]
}
)
)
MEMBER [exampleTuple] AS
(
[Measures].[Internet Sales Amount]
,[Date].[Calendar Year].[All].[2006+2007]
)
SELECT
[exampleTuple] ON 0
,{
[Product].[Category].[Bikes]
,[Product].[Category].[Clothing]
} ON 1
FROM [Adventure Works];

Answer 2

Do you mean creating a calculated measure or calculated dimension member?
Are you able to use EXCEPT or negation syntax?
Something like
(Measures.Number of accounts,Except{Status A,Status B}
or replace the word EXCept with a minus sign.
