SSAS 2012 Multidimensional DW has
Measures: Line total,
Dimension with hierarchy: [Division] - [Sales
Person].
I am trying to make set of top 2 salespersons by divisions.
This code sample gives me the correct result in SSMS:
with set [f] as
Generate(
{ [Sales Person].[Hierarchy].[All] . children },
[Sales Person].[Division].CurrentMember *
TopCount(
EXISTING [Sales Person].[Sales Person Id].children
,2
,[Measures].[Line Total]
)
)
SELECT [Measures].[Line Total] ON COLUMNS,
[f]
ON ROWS from [Adventure Works]
it's working fine. It will give me top 2 by division.
However, if i want to make named set in cube based on previous MDX thus:
create dynamic set CURRENTCUBE.[f] as Generate(
{ [Sales Person].[Hierarchy].[All] . children },
[Sales Person].[Division].CurrentMember *
TopCount(
EXISTING [Sales Person].[Sales Person Id].children
,2
,[Measures].[Line Total]
)
)
it will give me no error but this named set will not show in the browser. Validation of the MDX code in the calculations tab passes ok.
You say it won't show in the browser, have you allocated it a display folder? If not, it may not be where you expect to see it.
Can you use it in an MDX query OK?

Please consider this scenarios:
I have a cube with one Fact table and one measure called SalesAmount . Now I want to create a measure based on these 2 Selects:
Select 1:
Select [Measures].[SalesAmount]
From MyCube
Where [Product].[Color].[Gray]
and Select 2:
Select [Measures].[SalesAmount]
From MyCube
Where [Dates].[Calendar Year].&[2015]
The problem is in Add Calculate Member there is a box for simple formula. How can I create a measure for Select 1 + Select 2?
Thanks
I am not sure where are you looking at this Add Calculate Member option, but you could try something like this (Adventure Works database).
with member measures.[MyMeasure1]
as
([Measures].[Internet Sales Amount], [Date].[Calendar].[Calendar Year].&[2006])
member measures.[MyMeasure2]
as
([Measures].[Internet Sales Amount], [Product].[Color].&[Grey])
member measures.[MyMeasure12]
as
measures.[MyMeasure1] + measures.[MyMeasure2]
select {[Measures].[Internet Sales Amount], measures.[MyMeasure1], measures.[MyMeasure2] , measures.[MyMeasure12]} on 0
from [Adventure Works]
You can also create those members from Visual Studio Data Tools - in Calculations tab:
I got a cube with cadastral information of some neighborhoods of a city. One of the measures is 'cadastral value': the value of the land of a neighborhood.
Now, the city is divided into districts and a district, into neighborhoods (hierarchy with two levels).
The question is: I need to calculate the percentage that the value of each neighborhood represents compared with the parent (the district) and with the total (city), and also the same about the district compared with the city.
How can I do it?
I tried:
WITH MEMBER
[Measures].[Percentage] AS
([Nbh].[Nbh].[Nbh],[Measures].[Cad value].CurrentMember
/[Nbh].[Nbh].[Nbh],[Measures].[Cad value].CurrentMember.Parent)
SELECT
{[Measures].[Percentage]} ON 0,
[Nbh].[Nbh].[Nbh].AllMembers ON 1
FROM Cadastre
Where the dimensions are:
Nbh : Neighborhood
Cad value: Cadastral value
What I get is "error" in every result value, and the explanation is "Current member () : argument (0) type mismatch: expected:'level|hierarchy|dimension', got:'measure'"
What am I doing wrong?
WITH MEMBER [Measures].[Percentage] AS
([Nbh].[Nbh].[Nbh],[Measures].[Cad value].CurrentMember
/[Nbh].[Nbh].[Nbh],[Measures].[Cad value].CurrentMember.Parent)
There are two problems with this:
One, you are using a static set to compute the value of calculated member namely:
[Nbh].[Nbh].[Nbh]
This is NOT [Nbh].[Nbh].CURRENTMEMBER
Second and the bigger mistake: Using the currentmember on a measure. You can't do that. You can use Measures.CURRENTMEMBER but that's about it. It's best used on hierarchies which are used on axes.
That said, your approach is almost legit. You need to fetch the measure value for the parent.
This should work:
WITH MEMBER
[Measures].[Percentage] AS
DIVIDE
(
[Measures].[Cad value],
([Nbh].[Nbh].CURRENTMEMBER.PARENT,[Measures].[Cad value]) //Cad value for parent
)
SELECT
{[Measures].[Percentage]} ON 0,
[Nbh].[Nbh].[Nbh].AllMembers ON 1
FROM Cadastre
Try the following:
WITH MEMBER [Measures].[Parent %] AS
IIF(
[Nbh].[Nbh].CURRENTMEMBER IS [Nbh].[Nbh].[All]
,1
,[Measures].[Cad value] /
(
[Measures].[Cad value],
[Nbh].[Nbh].CurrentMember.Parent
)
), FORMAT_STRING = 'Percent'
SELECT
{[Measures].[Parent %]} ON 0,
[Nbh].[Nbh].[Nbh].AllMembers ON 1
FROM Cadastre;
Including the IIF is a defensive measure. If you switch to showing AllMembers of the complete hierarchy then the All member will be included. Here is an example using AdvWrks:
WITH
MEMBER [Measures].[Parent %] AS
IIF
(
[Product].[Subcategory].CurrentMember
IS
[Product].[Subcategory].[All Products]
,1
,
[Measures].[Internet Sales Amount]
/
(
[Measures].[Internet Sales Amount]
,[Product].[Subcategory].CurrentMember.Parent
)
)
,FORMAT_STRING = 'Percent'
SELECT
NON EMPTY
{[Measures].[Parent %]} ON 0
,NON EMPTY
[Product].[Subcategory].ALLMEMBERS ON 1
FROM [Adventure Works];
The above returns the following:
Without the IIF the expression is the following:
WITH
MEMBER [Measures].[Parent %] AS
[Measures].[Internet Sales Amount]
/
(
[Measures].[Internet Sales Amount]
,[Product].[Subcategory].CurrentMember.Parent
)
,FORMAT_STRING = 'Percent'
SELECT
NON EMPTY
{[Measures].[Parent %]} ON 0
,NON EMPTY
[Product].[Subcategory].ALLMEMBERS ON 1
FROM [Adventure Works];
We get the following because of lack of foresight:
The error is certainly because of this statement is incorrect:
WITH MEMBER
[Measures].[Percentage]
AS ([Nbh].[Nbh].[Nbh],[Measures].[Cad value].CurrentMember/[Nbh].[Nbh].[Nbh],[Measures].[Cad value].CurrentMember.Parent)
Try to make it like this
WITH MEMBER
[Measures].[Percentage]
AS ([Nbh].[Nbh].[Nbh],[Measures].[Cad value])/([Nbh].[Nbh].[Nbh],[Measures].[Cad value])
I recently started encountering strange problem as shown in image below. While browsing a SSAS cube, the Dimension Names appear blank.
Dimension: I have [Date].[Calendar Month].[Month]
Measure: [Services in 3 days]
After I run a query like
Select [Date].[Calendar Month].[Month] on 0 From [Service Cube]
then the Dimension Member Names show up in cube browser with different value for measure.
Any clues?
That's because you have blank members in [Date].[Calendar Month] hierarchy. To check 'em out, run the below MDX query:
WITH SET BlankMonth AS
FILTER([Date].[Calendar Month].CHILDREN, [Date].[Calendar Month].currentmember.MEMBERVALUE = '')
SELECT [Measures].[Services in 3 days] ON 0,
BlankMonth ON 1
FROM [Service Cube]
I am trying to select the top 10 products by internet sales from the Adenture Works cube (the cube I managed to compile with the Analysis Services Tutorial), I managed to do the cube perfectly, now I need to add a filter to add a specific product line and a given month and I don't know how to build the query...
I have this working:
with
set productNames as head(order({[Product].[Model Name].children}, [Measures].[Internet Sales-Unit Price], desc), 10)
select [Measures].[Internet Sales-Unit Price] on 0,
productNames on 1
from [Analysis Services Tutorial]
I added the filter and the result is the same...
with
set productNames as head(order(
filter({[Product].[Model Name].children},[Product].[Product Model Lines].[Product Line].&[R] )
, [Measures].[Internet Sales-Unit Price], desc), 10)
select [Measures].[Internet Sales-Unit Price] on 0,
productNames on 1
from [Analysis Services Tutorial];
Note: I can't use the hierarchy, because on my production database (which is not adventure works) I don't have hierarchies setup for the given problem.
Take a look at this query:
SELECT
[Measures].[Internet Sales Amount] ON COLUMNS
, TOPCOUNT([Product].[Product Line].&[R]*[Product].[Model Name].[Model Name],10,[Measures].[Internet Sales Amount]) ON ROWS
FROM
[Adventure Works]
The FILTER function is designed to filter a set of members that conform to a particular condition e.g. having Sales greater than £1000. It is not suitable for filtering a set by other dimensions or attributes. For this you can use the CROSSJOIN as I have done above (the *) and also the NONEMPTY function.
I hope that helps,

I have a simple olap cube - one set of measures and some unexciting dimensions.
I've add one calculation to get the "percent of total" sales against the gross sales measure. The code for this calculation is:
([Dim Stores].[Store Name].CurrentMember, [Measures].[Gross Sales])
/
([Dim Stores].[Store Name].Parent, [Measures].[Gross Sales])
This works.
Within the store dimension, there is a hierarchy called 'By State' where the stores are contained within.
Two questions please:
1. Any idea why the calculation would not work when I use the the 'By state' hierarchy i.e. the same calculation grouped by the next level up?
The state problem aside, any idea why my grand total shows an error even when I just use the Store Name?
TIA!
In poking around, I found a template within the "calculation tools" called "Percentage of Total". Using it, I translated my calculation to this:
Case
// Test to avoid division by zero.
When IsEmpty
(
[Measures].[Gross Sales]
)
Then Null
Else ( [Dim Stores].[By State].CurrentMember, [Measures].[Gross Sales] )
/
(
// The Root function returns the (All) value for the target dimension.
Root
(
[Dim Stores]
),
[Measures].[Gross Sales]
)
End
It worked!
