I am new to MDX and have just started using Named sets to group several members of a dimension.
Whenever I use a SET in a query, the results returned are always detailed out for each individual member of the set. I am looking to get one one for the set.
For example: I have two Measures: Sales Dollars and Shipped Units. The then have a State dimension for each of the 50 states in the United States.
I want to see the Sales and Units measures for 3 specific states and then also for a group (Named Set) of 4 other states.
Example MDX:
With SET [My Favorite States] AS '{[States].[Illinois], [States].[Wisconsin]}'
select NON EMPTY {[Measures].[Sales], [Measures].[Shipped Units]} ON COLUMNS,
NON EMPTY {[States].[Alabama], [States].[New York], [My Favorite States]} ON ROWS
from [cubename]
This returns:
Measures
States Sales Shipped Units
Alabama $100 5
New York $500 20
Illinois $150 15
Wisconsin $900 25
What I want is for the Set to appear as a total on a single line. Similar to:
Measures
States Sales Shipped Units
Alabama $100 5
New York $500 20
My Favorite States $1,050 40
Is there an MDX function that will allow the set of specific members to be treated as a group?
You can use a calculated member to aggregate the separate states:
With Member [States].[My Favorite States] AS 'Aggregate({[States].[Illinois], [States].[Wisconsin]})'
select NON EMPTY {[Measures].[Sales], [Measures].[Shipped Units]} ON COLUMNS,
NON EMPTY {[States].[Alabama], [States].[New York], [States].[My Favorite States]} ON ROWS
from [cubename]

My dataset looks something like this:
County Product Sales
CountyA ProductA 200
CountyA ProductB 150
CountyB ProductA 100
CountyB ProductB 300
CountyC Product A 50
etc...
I am using SSRS within Visual Studio. I am creating the map using the "Report Items" section of the toolbox.
I have the map with my state's counties, I associated the COUNTYNAME field with the County column in my data, but that's as far as I can get. I cannot seem to get the sales numbers to show on the map at all.
I can get the county names to show up on the map as labels, but that's not particularly helpful. If I choose [SUM(Sales)] nothing appears on the report.
Ultimately, I want a map of Product A sales vs Product B sales by county.
Is my dataset insufficient? And if so, what additional data do I need to add? Are there any steps I am missing to get the county associated with the sales column?
I want to define a cube measure in a SSAS Analysis Services Cube (multidimensional model) that calculates ratios for the selection a user makes for a predefined hierarchy. The following example illustrates the desired behavior:
|-City----|---|
| Hamburg | 2 |
| Berlin | 1 |
| Munich | 3 |
This is my base table. What I want to achieve is a cube measure that calculates ratios based on a users' selection. E.g. when the user queries Hamburg (2) and Berlin (1) the measure should return the values 67% (for Hamburg) and 33% (for Berlin). However if Munich (3) is added to the same query, the return values would be 33% (Hamburg), 17% (Berlin) and 50% (Munich). The sum of the values should always equal to 100% no matter how many hierarchy members have been included into the MDX query.
So far I came up with different measures, but they all seem to suffer from the same problem that is it seems impossible to access the context of the whole MDX query from within a cell.
My first approach to this was the following measure:
[Measures].[Ratio] AS SUM([City].MEMBERS,[Measures].[Amount])/[Measures].[Amount]
This however sums up the amount of all cities regardless of the users selection and though always returns the ratio of a city with regards to the whole city hierarchy.
I also tried to restrict the members to the query context by adding the EXISTING keyword.
[Measures].[Ratio] AS SUM(EXISTING [City].MEMBERS,[Measures].[Amount])/[Measures].[Amount]
But this seems to restrict the context to the cell which means that I get 100% as a result for each cell (because EXISTING [City].MEMBERS is now restricted to a cell it only returns the city of the current cell).
I also googled to find out whether it is possible to add a column or row with totals but that also seems not possible within MDX.
The closest I got was with the following measure:
[Measures].[Ratio] AS SUM(Axis(1),[Measures].[Amount])/[Measures].[Amount]
Along with this MDX query
SELECT {[Measures].[Ratio]} ON 0, {[City].[Hamburg],[City].[Berlin]} ON 1 FROM [Cube]
it would yield the correct result. However, this requires the user to put the correct hierarchy for this specific measure onto a specific axis - very error prone, very unintuitive, I don't want to go this way.
Are there any other ideas or approaches that could help me to define this measure?
I would first define a set with the selected cities
[GeoSet] AS {[City].[Hamburg],[City].[Berlin]}
Then the Ratio
[Measures].[Ratio] AS [Measures].[Amount]/SUM([GeoSet],[Measures],[Amount])
To get the ratio of that city to the set of cities. Lastly
SELECT [Measures].[Ratio] ON COLUMNS,
[GeoSet] ON ROWS
FROM [Cube]
Whenever you select a list of cities, change the [GeoSet] to the list of cities, or other levels in the hierarchy, as long as you don't select 2 overlapping values ([City].[Hamburg] and [Region].[DE6], for example).
I have an SSAS cube, that is producing unexpected results in Excel.
The problem occurs when I place a hierarchy on the report filter and then place a member of the same hierarchy on the row labels.
Example:
The hierarchy is called By Country, it is part of the Customer dimension. It contains three levels, Country, District and CustomerId.
By Country Hierarchy
UK Level 1 - Country
Essex Level 2 - District
Kent "
Hertfordshire "
West Sussex "
Suffolk "
USA Level 1 - Country
Montant Level 2 - District
North Dakota "
Oklahoma "
Texas "
I've not shown CustomerId, but this is a surrogate key. A unique value is issued to each customer.
When I place District on the row labels, I receive the expected breakdown of sales. However when I place By Country on the report filter, I lose the breakdown. Next to each district the total sales value is shown.
This does not happen when I repeat the example in BIDS.
This is a SQL Server 2008 R2 OLAP cube, used via Excel 2010.
Can anyone spot what I am doing wrong?
I have following data set as data Model.
Country City AssetCount
USA Newyork 50
USA Washington 40
USA California 30
India Bangalore 100
India Delhi 50
India Bombay 30
I want to show one row showing sum of Assetcount at country level & city level on the same row.
There are two slicers for slicing City & Country as below:
USA Newyork
India Washington
California
Bangalore
Delhi
Bombay
So when I select country as India it should show sum of Asset-Count at country(India) level.
In the same way when I select City as Delhi it should show Asset-Count at City(Delhi) level.
India Delhi
180 50
Is it possible using PowerPivot using DAX?

Actually your solution is not working. I have created the hierarchy as Country-->City & kept that in Rows. So when I select a particular Country & City it showing like this:
Row Labels AssetCount
USA 40
Washington 40
Grand Total 40
But I want
USA Washington
120 40
or may be like
USA 120
Washington 40
I have tried some aggregate functions like below:
=SUMX(VALUES(Query[City]),CALCULATE(SUM(Query[AssetCount])))
=CALCULATE(SUM(Query[AssetCount]),SUMMARIZE('Query',Query[City]))
Here Query is table for Data Model & City can be replaced by Country.
but not working.
So showing such counts on same row is possible or not?
Sounds like you are just getting started with Power Pivot. You might browse through the links on this page for more help.
I took the data you provided and pasted it into Excel.
Selected the data and clicked Add to Data Model and checked the box for My Data Has Headers.
I made sure the AssetCount Column had a data type of whole number. Then clicked the Pivot Table button and created a pivot table on my existing spreadsheet.
I put AssetCount in the values and made sure it was set to Sum in the Field Value Settings.
I selected my pivot table and then went to the Analyze tab under PivotTable Tools and clicked the Insert Slicer button.
I selected both Country and City as slicers.
This gives your desired result.
If you want the two numbers in a row, that's pretty straightforward. Keep in mind, that all those slicers do is putting filters on the pivot table.
Therefore to get your city result, you could use either an implicit measure or explicit measure that simply sums up AssetCount.
For the country result, you'd wish to overload the city filter like this:
=calculate(SUM(Query[AssetCount]),ALL(Query[City]))
If you also need the country and city names there, it gets a bit tricky.
I am new to MDX and I just want to ask if it is possible in MDX query to make aggregations and groupings on the fly.
Here is the scenario, I have a dimension called "Department". And it has department code values e.g.
1234
1257
1346
1390
I also had a measure called "Sales".
What I need to do here is to make a Calculated Member that will get the Maximum "Sales" grouped per department based on the its first two digits. For example, consider the following output when browsing the cube using the Department dimension and Sales Measure
Department | Sales
1234 | 100
1257 | 200
1346 | 100
1390 | 400
Then I need to make an MDX query to produce an output something like below,
Department | Sales
12xx | 200
13xx | 400
You will notice that Maximum Sales based on the two digits of each department concatenated with "xx" string were the expected output.
Well determining the maximum is not a problem. with <name> as max(<something>) but you should reconsider the approach with the on the fly grouping.
I'm sure, that it is achievable, although I cannot provide a solution, but it will perform poorly. (I'm assuming that the digits of the department are not implemented as measure)
If you need this grouping more often you should add an additional dimension, or better a hierarchy to the department dimension.
