Analysis :: Errors In OLAP Storage Engine - The Attribute Key Cannot Be Found When Processing

Jun 12, 2015

I 've read that there is a workaround for this issue by customizing errors at processing time but I am not glad to have to ignore errors, also the cube process is scheduled so ignore errors is not a choice at least a good one.

This is part of my cube where the error is thrown.

PK (int)MyMonth (int, Example = 201501, 201502, 201503, etc.) Another Columns
PK (int)Month (int, Example = 201501, 201502, 201503, etc.)

I set the relation between DimTime and FactBudget doing DimTime MyMonth as Primary Key and FactBudget Month as Foreign Key.
The cube built without problem, when processing the errror: The attribute key cannot be found when processingwas thrown.

It was thrown due to FactBudget has some Month values (201510, 201511, 201512 in example) which DimTime don't, so the integrity is broken.

My actual question: is there a way or pattern to redesign this DWH to correctly deploy and process?

Analysis :: AttributeKey Not Found When Processing The Cube

Apr 21, 2015

I have designed a cube. It has two fact tables and some dimensions. Fact table to fact table is many to many relationship.

For example

DataKey(PK), StartDateKey, PostCodeKey, TotalCost
DataKey(FK), ProductKey(FK), Position  - PrimaryKey on DataKey + ProductKey + Position
ProductKey(PK), ProductCode

Cube is built successfully, processed successfully.When I try to process the cube from agent job, I am getting error "Attribute key not found: tablename, value..." I have added a job step to run AnalysisServices Command. I have taken the command from cube process script(taken from manually process the cube and take script generated). I used ProcessAffectedObjects = "true" in the script. When I checked the tables, the key does exist. Why am I getting this error?

Question On OLAP Cubes Storage Modes

May 24, 2007

Hi, all experts here,

Thank you very much for your kind attention.

I am having a question on the SSAS2005 OLAP Cubes storage modes. We know SSAS2005 supports 3 different storage modes: ROLAP, MOLAP, HOLAP.

Do all these three storage modes of cubes store data in another physica analysis services databases which are inrelative from their data warehouse (in case they are built on top of the data warehouse)? (so it does not matter at all even we remove the data warehouse?)

Thank you very much in advance for your help and I am looking forward to hearing from you shortly.

With best regards,

Yours sincerely,

Analysis :: Cube Needs To Be Deployed From VS After SSIS Analysis Services Processing Task Completes?

May 13, 2014

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,

The Attribute Key Cannot Be Found When Trying To Process Mining Structure

Oct 29, 2007


I know, this is a common OLAP Error, but In fact I'm having trouble with this while trying to process a DM Mining Structure.
I'm currently working on a website that gets data from its users and analyzes it using SSAS. The thing is each time we add a new "analysis criterium" (sorry I'm trying to translate our french BI language in English...), we have to build a new mining structure, which needs data about users who have actually answered the question associated with this criterium. Some times, there are thousands, and some other only dozens, which is the case for the structure I'm having trouble with.

I got only 2 hundred tuples in the learning set. So lots of the common criteria weren't filled: I removed them using a stored procedure before feeding the structure, so that I got no column with only "null" values.

Of course, I know that 200 learning cases is really not enough to build an accurate model, but the purpose was just a proof of concept for machine driven Mining Structure building, and that was supposed to work even with so few cases.
When I process the MS, it fires: (Sorry it's in french, translation follows)
Erreurs dans le moteur de stockage OLAP : La clé d'attribut est introuvable : Table : _x0032_0_EtudeIphone_Apprentissage, Colonne : EtudeIphone, Valeur : le nouvel iPhone (téléphone tactile et musical dApple). Erreurs dans le moteur de stockage OLAP : La clé d'attribut a été convertie en un membre inconnu parce que cette dernière est introuvable. Attribut Id de la dimension : 20_EtudeIPhone ~MC-Id de la base de données : ClassificationVDCE, Enregistrement : 2.

Badly translated it says "Errors in OLAP Storage Engine: Attribute Key not found Table:<StrangeTable> Column <MyPredictableColumn> Value <OneOfTheInterestingValues>
Errors in OLAP Storage Engine: Attribute key not found: converted to an unknown member. Attribute Id from dimension..."

Why? Too few cases? I have structures based on the same template but associated with other criteria and they work perfectly.

I'm ready to answer any question, and give any detail.
Thanks in advance.

OLAP Cube Partition Processing ...

Apr 25, 2008

We have a MS-OLAP cube that has about 11 partitions and I have created a prototype package which processes these partitions conditionally based on expressions that are fed values from a SQL Server control table. It appears that one or more of the partitions seem to fail due to the fact that all of the data for the various partitions come from the same huge fact table. Is there a way to control the level of concurrency within the package itself? If not, I am thinking I should move some of the partitions to process based on other partitions completing their process successfully. Appreciate any help.

OLAP Cube Processing Project ...

Apr 28, 2008

I am trying to log the processing time details so that we can identify bottlenecks. My SSIS package has a bunch of OLAP processing tasks. In the Event Handler (onPreExecute and onPostExecute events), I am trying to capture the start and end time for each OLAP processing task by using an "Execute SQL task". In the event handler, I have a conditional expression that checks the following:

@SourceName != @[User::Expression1]

where Expression1 is a variable that contains the value of "Execute SQL Task". This expression I thought would be true only for OLAP processing tasks which btw never fire the OnPreExecute or OnPostExecute events. What am I doing wrong?

Frozen OLAP Processing. Any Ideas?

May 11, 2007

All, I am using SQL Server 2005 Developer's Edition on Windows XP Home Edition.

With the microsoft provided sample database AdventureWorksBI.msi comes with an analysis services solution called "Adventure Works DW"

Processing this solution should to produce the "Adventure Works DW" Analysis Services database.

This processing never finishes. It hangs on Processing Cube 'Customer Clusters ~MC. Specifically it hangs on Processing Partition 'Internet ~1 ~MG'. This looks like something having to do with Business Intelligence.

I am wondering if my installation "Operating System" is correct or allowable for "SQL Server 2005 Developer's Editon?

I wonder if I need to set any special security for Data Mining? As anyone had any experience with 'never finishing' Analysis Services processing.

All, opinions are welcome. I would 'like' to hear all 'possible' solutions.

Any ideas or opinions?

Thank you very much.

Temdb Is Full When I Run DTS Task With OLAP Processing

Oct 20, 2006


I have some problem:
Evryday I autmoaticaly run SqlAgent job with DTS task that run tasks:
1. SQL Task: Shrink tempdb database
2. Analysis services task: Process ALL Database

From some time the job fails to run. I have error indicating that tempdb is full
The error string is: "The log file for database 'tempdb' is full. Back up the transaction log for the database to free up some log space"

The size of temdb file growth to 20GB.
When I process Databse manually in Analysis Manager the database process correctly (because Analysis Manager do not use tempdb but temp folder)

What I should do in this case?
I shrink tempdb before every processing so back up of transaction log will not help me.
Any sugestions?

I'am using SBS 2000 Standard Edition ENG with installed components:
Active Directory
Exchange 2000
SQL 2000

System has 4GB RAM and 2 XEON CPU.

Thanks for any info.

Analysis :: How To Get Dimension Key Attribute In MDX

Apr 30, 2015

Many dimensions don't have unique members.  Instead, the dimension source data has duplicates at the leaf level: it's left up to SSAS to aggregate up to the actual leaf level used in hierarchies.

Every cube I've worked on in the past, a dimension is clearly defined in the source data, with uniqueness already present there: we don't make a dimension out of duplicated, sort of facty data.  This kind of design seems as weird to me as an unnormalised SQL database.

Here's an example to illustrate what I mean; I'll use that Adventureworks database.

We have a Geography dimension with a Geography hierarchy.  Levels go like this from top to bottom:


The Geography dimension has a key attribute called Geography Key.  It's there in the cube design as a dimension attribute, but it's not in any of the hierarchies, so I can't query it in MDX.  But that's fine: it has the same cardinality as the lowest level (Postal Code), because the dimension has some kind of normal design.

In the cube I'm dealing with, it's all messed up.  Using the AdventureWorks example above as a parallel, someone made a Geography dimension with source data keyed on [PostalCode, ExactAddress], but only wanted the dimension granularity to be PostalCode.

This makes it very hard to debug why the data in this dimension is incorrect.  I can't match up the dimension members in the cube to the source data, because the dimension doesn't actually go down to the real leaf level!

So I have a dimension attribute called ExactAddressKey, but I can't query on it in MDX, because it's not part of any dimension hierarchy.  Unfortunately changing any part of this cube design is not possible, so I can't even experiment with settings and see what happens.

How I could get to the leaf level of the data imported?  Something like


Or does this kind of dimension design result in SSAS discarding all the data that's more granular than the most granular attribute defined in any hierarchy - so that the data actually isn't there to be queried?

Analysis :: Calculated Attribute In SSAS?

Sep 17, 2015

I've been working with SSAS for a good few years now but I keep bumping into this problem - my users are trying to build a measure that is based on a calculated attribute and finding it difficult to work out how to write the MDX to do so. Intuitively, they thought a Calculated Member would work, but I don't think a Calculated Member is quite the same thing from my understanding.

So, here's the scenario.

We have a Product Dimension. We have a Measure that is the Number of days the Product took to make, e.g. 5 days. We also have a Product Count measure that counts the number of Products.

The user would like to write a calculated measure that works out the number of products that took <5 days, 5-10 days, 10-15 days etc.It would be easy to write a set of calculated measures for each of these bandings, but the user wants effectively a single dynamic attribute to use in the calculation in order to automatically distribute these values across the columns in their pivot table.

Is this even possible? I was thinking I could build an attribute on the Product Dimension in the ETL to do this quite easily, but the user wants to be able to change the bandings on the fly by changing the MDX for the attribute, rather than go back to the developer every time.

Storage Design Analysis Manager

Feb 27, 2008

I have a question about the storage design wizard in the analysis manager.

We are working with different seasons in our reports and every week we update the data of the seasons in our cubes. But as seasons end, and at some point the data for old seasons doesn't change anymore, I don't think it is necessary to update every season every week (which we now still do now for seasons in, for example, 2004). It's a waste of time. So my question now is. How can I storage the data of previous seasons (and work with them in the report) and still be able to update the current season? Can I use the storage design for this??

Analysis :: Using Named Set To Filter On Dimension Attribute

I am unable to find solution for the problem while writing a Named Set in my cube.

I have a calculated measures which gives me difference in Sales in PERCENTAGE (%).

When I try to filter out those product codes which went a less than 5 %, I get no records.

I have also tried to filter direct values lets say - Products with sales > 100000 which is working fine.

Following is sample of my Named Set

FILTER([X].[Products Code].members, [Measures].[Diff in Sales]<5)

I believe as the values are in percentage, I am facing this issue.

Mssql Equivalent Of Mysql Merge Storage Engine

May 13, 2008


Mysql database provides a storage engine called "MERGE".A "MERGE" table is a collection of identical tables that can be used as one.(Identical meaning same column name,column width, column order etc.) .

The advantage is you can split a really huge table like LOG tables, STATS tables into seperate smaller tables but would still be able to make queries on them like a single table. More details, can be got from here:

My question is that do we have an equivalent of MYSQL "MERGE" in MSSQL ????

Analysis :: Best Way To Add Additional Parent Child Attribute Values

Apr 16, 2015

I have a parent Child attribute in my dimension.  I am currently displaying the correct ID value as the business wants.  So now they can see the rollup of the ID(intOrgNodeID ) values.They would also like to see the same rollup of the Name (vcharOrgNodeName)  for this ID.However they do not want it concatenated.  They want to be able to see them separate.You cannot create two parent child attibutes in one dimension so not sure if there is some simple trick to make this work? It seems like there should be some simple trick for this. 

My dimension table looks something like this
intdimOrgNodeID int Key (surreget key)
intOrgNodeID int (Actual ID)
In the Propertys I have set this below.
KeyColumns  = tbldimOrgNode.intDimParentOrgNodeID

Analysis :: SSAS Named Set With A Two Dimension Attribute Tuple

Jul 15, 2015

In my SSAS Cube I have created a dynamic named set "top 10 e-learnings by language" which consists out of a set of tuples. Each tuple has two attributes out of the same base dimension "training": attribute 1 is "sprache" (language) and attribute 2 is "training text".

CREATE DYNAMIC SET CURRENTCUBE.[Top 10 eTrainings pro Sprache]
AS Generate(
{ [Training].[Sprache].[Sprache].Members },
EXISTING { [Training].[Sprache].CurrentMember * [Training].[Training Text].[Training Text].Members },
[Measures].[Teilnahmen eTraining]
), DISPLAY_FOLDER = 'Training' ;

Normally a named set would be automatically visible in Excel Pivot under the dimension you used to create the named set, but it seems that named sets with tuples which have more than one attribute are placed in a separate folder "Sets" in between the measures and dimensions.Additionally in the SSAS cube browser this named set is not visible at all.Is there any way to tell the named set in which dimension it should appear or any workaround?

Analysis :: Attribute Relationships Impacts On Members Full Unique Name

Aug 17, 2015

Our SSAS integration didn't initially use attribute relationships.Now that our system has been running for a few years and we have bigger databases, we think we need to add them to improve performance. So we're in the process of adding them but we found out that, when attribute relationships are added, the full unique name of our members all go from something like:

to something like:

It looks nice and SSAS will accept the longer names fine but it will return the short ones in response to 'discovery' requests and in the XMLA response of MDX queries. This is causing problems in our low level XMLA-based modules that assume the long names in and out. is there any clean way to use attribute relationships and still have SSAS generate the long member names. We fiddled with the various documented dim/attribute properties but to no avail. It also appears that some switches are obsolete.
