Analysis :: SSAS Multidimensional Cube On A Single Table
May 7, 2015
I have only 1 denormalized table that is being used in a SSAS Tabular model(which is about 3GB). I am doing a POC to convert it into a SSAS Multidimensional and explore it.
Table1
-----------------------
StoreName
StoreDesc
ItemName
ItemDesc
Qty1
Cost1
Price1
Amount1
1st Question) I am seeing that there is no Primary Key(unique key) in the current denormalized table. (Tabular Model didnt require any primary key). But i think for Multidimensional the key is mandatory? Should i generate a composite key myself in a Named Query based on this table(in the DSV)?
2nd Question) What is the best way to design my Multidimensional Cube/Dimensions based on this single table?
Say if i comeup with a Composite Primary Key called (PK_ID) . Should i be splitting up my facts / dimensions in my DSV using Named Queries similar to below(Using the same PK for my dimension tables also?)
a) FactTable = Select PK_ID, Qty1,Cost1,Price1,Amount1 from Table1
b) StoreDim = Select PK_ID, StoreName,StoreDese from Table1
c) ItemDim = Select PK_ID, ItemName,ItemDesc from Table1
Would this work?

All I get back is an error message of "Analysis Services Processing Task Error: A Connection cannot be made. Ensure the Server is running" The server is running, I can process the cube by connecting to the AS instance and right-click processing it.
I can process the cube by running the SSIS task inside of SSDT Just when I deploy the SSIS package (in Project mode) and then execute it do I get the error message.
SQL Server, SSAS, and SSIS processes are all running under the same account. SSAS is on a separate server from SSIS and SQL if that matters.

I have created one Multidimensional CUBE, while browsing(Analyze in Excel) it in Excel, I am unable to create TimeLine Slicer.It is giving me following error as: "We can't create Timeline for this report because it doesn't have field formatted as Date".
I have Dim_Date having Date as a column of Day level granularity. In PowerPivot, we do mark Dim_Date Table as a 'Date Table'.In the same way, do we have to set anything here so that Excel will come to the Date format for TimeLine Slicer?

I am trying to implement data masking based on user login and not sure why this is not working. I have the dimensions DimBrand, DimProduct and DimUser. I should mask the BrandCode with 'XXXX' nothing but in the report all the BrandCode should appear but few of the code will be masked if the user is not belongs to that group. I have a fact table FactProduct in this. In the cube I created all these 3 dimensions and the fact table. I created a new dimension DimBrandMask and I separated the code over there with a relationship with the actual DimBrand dimension. In the cube a reference relationship is set up with the measure group. Created a role with read access.
In the dimension data tab of role I put the below MDX to allowed set.
NonEmpty([DimBrandMask].[Brand Code].Members, (StrToMember("[DimUser].[Login Name].[Login Name].[" + UserName() + "]") ,[Measures].[Dim User Count]))
And in Denied Member set i put the below MDX
IIF( (StrToMember("[DimUser].[Login Name].[Login Name].[" + UserName() + "]"), [DimUser].[Access Right].&[False]), NONEMPTY( [DimBrandMask].[Brand Code].Members,(StrToMember("[DimUser].[Login Name].[Login Name].["
+ UserName() + "]"), [DimUser].[Access Right].&[False], [Measures].[Dim User Count])),{})
Note I created one measure group from the DimUser table and the measure [Dim User Count] is used in the above query.
I am expecting some result like below
Brand BrandCode Count
Brand1 b1 6
Brand2 XXXXX 5
Brand3 XXXXX 10

how can use this mdx script in the calculation part of a cube, will i simply dump it in the script form by starting with the 'create member current cube.
[measures].[test]'
select
[measures].[abc] on 0,
[xyz].[xyz].(&0):[xyz].[xyz].(&60) on 1

Is it possible to have more than one cube under one SSAS database? For example I have a database "Test" and in this the cube exist is "TestCube", is iit possible to deploy another cube "TestCube2" under the Test databse?
If yes then what is the process to do that, the reason I am asing is there are some common dimensions used n both the cubes and I am not sure what is the best way so that I can use the shared dimension?

I am thinking of a possible design where the cube will never go offline.
Usually when I do some code changes on my cube the cube goes offline and I need to Full Process it again to get it back .
However , in cases where the cube is extremely critical for the business users , it would be great if I can deliver a solution where the cube never goes down.

Background: I have a Huge fact dimension table(table has both measures and dimensions) that i am using to build a SSAS Cube.
The table didn't have a unique identifier, so the database team added ROW NUM as a column to the table which i am using as a PrimaryKey in my Cube build. I was able to create a cube successfully with it without any issues.
Problem: Now customers are asking for a 'Claim Count calculation' which shows the Distinct Claim Count.
Its defined as below :
Count(Distinct Claim_Number || Claim Year || Claim Month)
. All the 3 columns are available in table, but when i am trying to create this Count Distinct Object in the DSV the Cube processing time increased by 5 times, as now i have to use a GroupBy function in my SQL.(There are around 30 columns to group by).
Is there a better way to achieve this Count(Distinct Claim_Number || Claim Year || Claim Month) without using groupBy in DSV SQL logic? I cant seem to find any Count(Distinct) function in the Cube Calculation functions?
Environment: SSAS 2012 Multidimensional Model

I am working on SQL 2012.We have a SSAS Cube build. On top of it client use Excel to connect to SSAS Cube and See the reports.My Cube process every hour and take almost a 1-2 min to Process.When ever End user/Client See or refresh the Excel report (Which use Cube as Source),WHEN CUBE IS PROCESSING ,they get an error that Source is not available
We Have tried best but cannot bring down the Processing time of the cube to 3-5 Second , so that End user don't face report refresh issue at the moment of cube processing
Requirement :In Case End User see the report while Cube is processing from back end , Instead of Error they should see some customize Msg which we can provide some thing Like "Data is Refreshing , please wait ".

Is there any way to copy my Data of 2015 to the Planning/Forecasting Value of 2016?
My question is based on that we use INFOR ION BI right now and there we can just add an Button in our reports wich physically copies the value from one year to the next year based on some other rules in the cube.
Now I need to make this example work with SSAS and Excel PivotTables but I cant figure out how.
I have absolutely no clue where and how to accomplish it. Do I use Calculations, do I use Actions, do i make it in the Dataview, Cube or directly in Excel?

I am facing a very weird issue in our SSAS database. We have several roles with 'Read definition' access. None of these roles are able to see data in the cubes. I have checked these roles over and over and there is no problem with the definition. Each of the roles have been given read access to Data Source, Cube and Dimensions.
The users are able to access the definition and structure of the cube i.e. they can see the measures & dimensions available but when they drag measures and dimension attributes in the browser (SSMS) OR execute an MDX - they get null values. The roles with 'Full Control (administrator)' access are able to see all the data without any issues.
I have tried the following:
1. Deleted all roles and re-created.
2. Created roles directly on SSAS DB.
3. Deployed all objects and processed the DB.
Each time only the admins are able to see the data.

I've created a cube and it processed fine. The calculate command is there. The measure that I'm attempting to run in the SSAS/Visual Studios browser is simply a count rows measure. When I drag the measure to the window, it says no rows available. If I click on the filter that allows nulls, the only change it makes is that it goes from no rows available to "NULL".

Running PivotTable reports in Excel 2007 which are linked to a SSAS Server 2008 R2 may consume high amount of memory and cause high CPU utilization.
Detail:users may set 7 or more dimensions in row section of a Pivottable report. Some of those dimensions were containing more than 10000 members.
When refreshing such a report, Analysis Services is consuming more than 16 GB of memory, cpu utilization often goes up to 80%.
To run this report it takes arround 10 minutes. During this time other users may be unable to run reports on the server.Is there a way to control expensive MDX queries caused by some users to ensure Service availability?

I need to extract data from SSAS' cubes into a SQL Server table.
I already read examples using Linked server (with openquery), SSIS, etc. However, the result always return as many columns per dimension as levels. I need to extract all members of a dimension in a column. E.g., when excecuting the following MDX query in Adventure Works 2014:
select [Measures].[Sales Amount] on columns,
Non Empty [Date].[Calendar].members on rows
from [Adventure Works]
I would like to get this result (MDX query in SSMS), but with keys displayed intead of names:
But I get this (MDX thru openquery or SSIS):

I am working with SSAS Tabular. I have a stand alone table with 60 columns and contains 120K records. Table size is 250MB. And trying to build a tabular report out of it and it is taking longer and throwing exception, screenshot attached.
It might be cross-join issues, as workaround created a dummy measure and using in report. But it working for 10-20 k records and beyond throwing same exception. I have 8 GB RAM and 100 GB free disk space.
Customer wanted it in SSAS Tabular...

Is it correct to say that for each cube you can have only one Fact Table? I am having a funny dispute just now.
According my experience I never built cubes with more than one fact table, if I want take data from more than one table I write a view and I use it as Fact table...but a cube with two or three fact tables? Never tried..

I am developing a BI solution on SQL Server 2008 R2 and how to handle multiple referances to the same dimension from a fact table!
Here is the scenario;
Fact_Contracts (# M)
ServiceProvider_CompanyID, Client_CompanyID, Amount_USD
Dim_Company( hundreds)
ID, CityID, ProfessionID, CompanyName
Dim_City
ID, CityName
Dim_Profession
ID, ProfessionName
As u can see there is two company references in my fact table, and the schema is in snowflake. My customer requirements state that the Contracts' amounts can be aggregated/filtered for/by, ServiceProviderCompany, its city/profession or ClientCompay, its city/profession.
First thing came in to my mind is to dublicate whole dimension structure (one for serviceproviders, one for clients), which i thought that there should be another way around?

I have problems creating a cube with AMO.
I can add the cube to the database object and fill it with dimensions and a measuregroup (see code below).
If I call cube.Update() it says something like "Error in meta data manager. Cube has no measuregroups." (getting the message in german language)
The error in Microsoft.AnalysisServices.OperationException.Results.Messages is -1055653629
I can't find any documentation about this (or any other) error code in Microsoft documentation.
Here's my Code:
Cube newCube = database.Cubes.Add("MyCube","MyCube");
newCube.Language = 1031;
newCube.Collation = "Latin1_General_CI_AS";
CubeDimension dim = newCube.Dimensions.Add("dim1","dim1","dim1");
CubeAttribute attrib = dim.Attributes.Find("dim1Attr1");
[code]....

I have a very small SSAS database with around 35 Mb. I opened it on Excel 32 bits and started dragging fields to a pivot table and it started failing with memory errors. The behavior on the SSAS server was that memory started growing very fast until 8 GB (vm memory total) and then the error is reported in excel.
What might be the issue in such a small database? I would understand in a big database, but not on this one.

I have a cube that we are processing nightly via an Analysis Service Processing Task in SSIS. In order to increase the performance of the processing time, we elected to use a lot of rigid dimension attributes, and do a full process of everything in the SSIS task. The issue that I am having is that after that task completes, I need to go into Visual Studio to deploy the cube becuase we are unable to browse or use the cube. This issue seemed to start once we changed the SSIS Analysis Service Processing Task to do a full process on the dimensions, rather than an incremental.
I would expect that once development is done, and it is processed and deployed, that is it. My thinking is that the SSIS task should just update the already deployed cube,

Hi,
I have a problem with processing my cube. My fact table (with telephone data) contains about 400,000 records... which is increasing rapidly (400,000 records is about 8 months of data)...
I have a few dimensions:
Dimension User: about 200 records
Dimension Line: about 200 records
Dimension Direction: 4 records
Dimension Date: 365 records for each year
Dimension TimeInterval: with 24 records
So far so good... when I process this dimension I have no problem....
However, when I add a dimension (CalledNumber, with exactly 101 records) the processing hangs as soon as it starts...
The SQL performed when processing the cube looks like this:
SELECT field1, field2,... fieldn
FROM table1, table2,.... tablem
WHERE
(table1.id=table2.table1id)
AND
(table2.id=table3.table2id)
...
When I execute above SQL in the Query Analyser from SQL Server Enterprise Manager, it ALSO hangs...
I am not really suprised by that, because this SQL first create a huge table of 400,000 x 200 x 200 x 4 x 365 x 24 x 101 records and after that works through the WHERE statements to filter out the appropriate records.
for me it would be more logical to use the following code to process the cube, but that cannot be changed in Analysis Manager:
SELECT field1, field2,... fieldn
FROM table1
LEFT JOIN table2 ON (table1.id=table2.table1id)
....
LEFT JOIN tablem ON (tablem.id = tablem-1.tablemid)
When I execute above SQL in the Query Analyser from SQL Servel Enterprise Manager, it does NOT hang, but performs the query in about 35 seconds....
But Analysis Manager does not allow me to change the SQL used for processing the cube...
What can I do to add more dimensions to my cube... (It will be more anyway after adding the CalledNumber dimension)??
any suggestions?
PS. forgot to mention: I use Sql Server 2000
