SSAS 2008 Dimension root values changes after incrementally loading the dimension with 'process_up

Posted By:      Posted Date: September 01, 2010    Points: 0   Category :Sql Server
The Dimension root  members (below 'ALL') changes after incrementally loading the dimension with 'process_update'.  How do I prevent that from happening ? There was no changes to data of the underlying table of the dimension.

SSAS 2008 Dimension: Multiple FK Relationships to the same Dimension



I have kind of a fundamental design question: In my DWH are 2 tables TICKET and EMPLOYEE. EMPLOYEE is referenced by TICKET 2 times: TICKET_OWNER_ID and TICKET_ASSIGNED_TO_ID.

I have created a Ticket and a Employee dimesion in my SSAS Project. The Ticket Dimension should no have two atrributes: Owner and Assigned To. I can create the attributes by dragging the EMPLOYEE.NAME column from the DSV window into the attributes list but there is now to specify which relation will be used.

And of course I get pretty intresting results when I process the dimension.

I could create a named query in the DSV selecting * from EMPLOYEE and create a second Employee dimension but is that the only way I can get this to work ?

Thanks, ITD

SSAS 2008 - The OLAP data source has no property fields available for this dimension


Last week I was able to view member properties for my Product Dimension in Excel 2010 pivot tables. Suddenly, without having made any changes to the dimension (for example, in the Attribute Relationships window of the dimension), those member properties are no longer available in Excel. I get the error "The OLAP data source has no property fields available for this dimension" when I try to select "Show Properties in Report" or "Show Properties in Tooltips" in the Pivot Table. At the same time, member properties are available for all other dimensions. I have also not made any changes to the data source connection in Excel and in any event, there is no option in the data source connection to enable or disable member property visibility. I am using BIDS 2008 and SQL Server 2008 R2 (10.50.1600.1). Does anybody have an idea why this might be happening?


SSAS 2008 - Dimension colmun/attribute not visible in cube browser?


Hi, I have one dimension and one fact table in SQL 2008 server...

i.e. DimEmployee (Columns : EmployeeID, FirstName, LastName, DateOfBirth, Addrss, PostCode, MobileNumber, Gender)
     FactEmployeePay ( Columns : EmployeeID, Amount)

When I create SSAS 2008 cube on those two tables (Relationship is EmployeID colmun) , deploy/process project/cube and then I go to "Cube Browser", but in dimension Employee table I can not see any columns other than EmployeeID. Why in this simple cube I can not view other dimension columns like FirstName, LastName,....

Any idea for SSAS 2008?


how to sort date dimension in SSAS 2008?


Hi I have SSAS 2008 DimDate dimension.

At source DimDate table has:
DateID : 20100518 (primary key), 20100519, 20100520,... (and SortKey too at T-SQL level)
MonthName : April, May, June,....
MonthNameYear : April,2010  May,2010  June,2010

I would like to sort dimension by MonthNameYear's attributes (currently I have order like January 2001, January 2002, January 2003.... but I want order like January 2001, Feburary,2001,March,2001 .......)
In SSAS visual studio, in Date dimension structure >> Attributes panr>> Month Name Year (properties : OrderBy, I set to Key, Name, AttributeKey, AttributeName and deployed but no luck in sorting).

Any idea how to sort date dimesion attributes? Thanks.

Process Update does not reflect change in case of dimension member in SSAS 2008.


Process Update does not reflect change in case of dimension member in SSAS 2008. We can replicated this issue in Adventure Works 2008 with below steps.


1.  Customer Name Aaron Allen is in Title case both in Adventure Works SQL 2008 Data Mart as well as in SSAS 2008.


2.  Change Customer Name Aaron Allen to Upper case in Adventure Works SQL Data Mart.


Dynamic Dimension with Aggregate Values

Hi, I have an specific requirement to make the measure value as an dimension. Let me explain my problem in brief. I have a fact table with dimensions like Time, Products etc and having single fact table with two measures. I have to create a calculated measure which shows the average of Measure 1 (here used calculated measure because there are couple of other calculations involved). And other two calculated measures. when I drill down with Products dimension for Calculate measure 1, it shows the average value for each products. Now, I want this calculated measure values (includes Product dimesnion drill down) as a Dimension and based on this value, I need to show the value of other two measures. For example: when the dimension products is used for drill down the values displayed will be like this and in this I need CM1 to be another dimension Products CM1 CM2 CM3 P1 0.10% 20 1 P2 0.20% 40 2 P3 0.30% 80 3 P4 0.40% 70 4 P5 0.50% 30 5 P6 0.60% 110 6 P7 0.70% 120 7 P8 0.80% 130 8 P9 0.90% 86 9 P10 1.00% 65 10 when CM1 is used as a dimension it should show the value like this CM1 CM2 CM3 0.10% 20 1 0.20% 40 2 0.30% 80 3 0.40% 70 4 0.50% 30 5 0.60% 110 6 0.70% 120 7 0.80% 130 8 0.90% 86 9 1.00% 65 10 How can we create the dynamic dimension with the aggregated values? Any assistance will be greatly apprec

SSAS - How to get other members from dimension that has Parent Child hierarchy?

I have a Sales Territory dimension that has employee and parent employee attribute on which parent child hierarchy is defined and it gives below hierarchy while browsing - - Mark Rolls --- Lumin Jacs ----- Larry Gomes ------- Messica Owens ------- Tom Ted ----------- Jackson Lopez ----- Matthew Ron --- Fred jacob - Jason Ron --- Jecy Pedro   But beside this parent-child hierarchy I have other attributes like employee address, email and telephone. My facts related sales transaction is tagged to lowest level. For example here facts are available only for Jackson Lopez (being Field Executive). When use below query I get complete sales reporting hierarchy result with some measures like sales amount, sales volume. But while accesing other attributes like address or email, it's repeating address/email/telephone of jackson Lopes everywhere to whom fact record is linked, Actually I want address/email/telephone of each sales employee from that dimension within hierarchy. How do I get it? The query I used is: Here Parent Terr ID is parent child hierachy. SELECT ( Descendants( { [Dim SalesRegion].[Parent Terr ID].[Employee Level 01].&[538018] /* here Mark Rolls is 538018 */ }, 0,AFTER), NONEMPTY([Dim SalesRegion].[Emp Address].[Emp Address].Members), NONEMPTY([Dim SalesRegion].[Emp Email].[Emp Email].Members) ) ON ROWS , { ([Dim Date].[The Year].[The Year].[CY-2010], [Dim

How to Create an MDX Query Parameter to Select 30 Values from a Dimension?

Hi, I'm using SSRS 2005 to report on an SSAS cube that contains a Procedure dimension.  I don't need to use members of this dimension in my report, but rather need to select records (patients) where their chart has one or more of the codes.  I've researched this today and cannot locate the best approach.  Thus far, I've attempted to create an MDX query parameter as part of my dataset.  However, I don't know whether this is the correct approach, and how to structure the syntax so that only records with one or more procedures are included in the report?  If so, what is the proper MDX syntax for setting my Procedure code equal to the query parameter? Thanks, Sid

SSAS 2K5 - Server time dimension

Hi, I'm building a cube and I want to add a time dimension. I don't have any time table in my OLTP (Source) database. So I tried to use the wizards from SSAS to create a time (date) dimension. I have choosed the "Server time dimension" one. It did create all what I need with all the hierarchies. But when I tried to add time business intelligence with the wizard, it doesnt see my new time dimension. I have checked if the type was "time" for the dimension and It was ok. So I don't know why the Time intelligence can't see my time table .... btw, I start the Business Intelligence wizard from the cube.   Thanks

SSAS 2K5 - Name of the dimension included in attributes

Hi I have a fact table with 2 field using the same dimension table. So, in SSAS 2005, The dimension is added (Lets say dimXYZ). So the dimYXY is used for 2 field in my fact table. When I go in my "dimension usage" tab ... i'm adding the 2 dimension that are bind to 1 physical dimension wich is dimXYZ. So I rename (in the dimension usage tab) the dimension freshly added. ("Dimension AB" and "Dimension CD"). But when I browse the cube, the attributes are displayed like Dimension AB.NameOfAttributes and Dimension CD.NameOfAttributes) Is there a way to hide the name of the dimension in the attributes ? Thanks * Sorry for the bad english ... I speak french ;-)--------------------- Richard Martin

Avoiding a SELECT distinct query generated by SSAS when using dimension derived from fact table

Hi, I am using a dimension derived out ot a fact table and the factt able primary key is dimension key. Issue is, there are large number of rows and so many attributes. SSAS issues distinct query and it takes large amount of time. Without the distinct statement, query takes only 3 min for 4 million rows. With the distinct, it takes 20 min. Becuase the fact primary key is the dimension key there is no need of a distinct statement. I know there is a option in the dimension to say "By Table" to avoid this. But unfortuantely, i breach the 4 GB limit for strings. Any suggestions for optimization? Thanks,  Sambath

Dimension Usage for non key values


I have, for purposes of this question, have 3 tables.


The ERD is:

What I need is:

For each record in the DimIVRCompletion Count the number of records in the FactEventIVR table where the ActivityCode is equal to the EntranceCode and the count where the activitycode is equal to the Completion code, then divide the Entrance Count by the Completion Count to get a percentage of completion.


The following MDX is what I think should be the query.




Member [Measures].[CompletionCount] as


{[Dim IVR Completion Code].[Completion Code Key].[Completion Code Key].Members},

{([Dim IVR Completion Code].[Completion Code Key].CurrentMember)} *

{[Measures].[Fact Event IVR Count]})

Member [Measures].[EntranceCount] as 


{[Dim IVR Completion Code].[Entrance Activity Code Key].[Entrance Activity Co

SSAS - performance penalty standard dimension without custom member formulas VS standard dimension w


Hi all

I was wondering if there is a big performance penalty if one introduces custom member formulas to a standard dimension.


SSAS - Use simultaneously unary operator and custom member formula in a PC (Parent-Child) dimension


Hi all

I was wondering (even this might a very bad idea from a logical and performance perspective) if it is possible to use unary operator and custom member formula simultaneously? Until now I have used unary operator but now some new calculation can't be expressed using unary operator. The idea is just to add the new members calculation to custom member formulas. Is it possible to make cohabitate both. If I had to switch all unary operators to customer member formulas what would be the equivalent expression for +, - , ~?

thanks for your answer


Can we pass dimension values as parameters in MDX


Hi All,

I am doing something similar to basket analysis and I wrote an MDX to see the trend of purchases over time for a customer. How can I dynamically pass values of customer or product purchased into mdx? In below example how can I change [product].[category] value? Also, can we change the dimension also dynamically?
