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

Oct 29, 2007

Hi,

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 cl̩ d'attribut est introuvable : Table : _x0032_0_EtudeIphone_Apprentissage, Colonne : EtudeIphone, Valeur : le nouvel iPhone (t̩l̩phone tactile et musical d۪Apple). Erreurs dans le moteur de stockage OLAP : La cl̩ d'attribut a ̩t̩ convertie en un membre inconnu parce que cette derni̬re est introuvable. Attribut Id de la dimension : 20_EtudeIPhone ~MC-Id de la base de donn̩es : 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.

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.

DimTime
PK (int)MyMonth (int, Example = 201501, 201502, 201503, etc.) Another Columns
FactBudget
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?

Measure Group Attribute Key Column Does Not Match Source Attribute

May 16, 2008



HI,


I had to change the key columns of a dimension attribute to fix an error. I did this in BIDS. The change was from a single key column to a composite key column. Now I am getting these error when I process the cube:

Measure group attribute key column x does not match source attribute ..

I looked at the cube XMLA definition under mesaure groups and it still shows a single key column with inherited binding. However, the BIDS does not give me an option correct this in any way. I have had to do this once before and the only option seems to be removing the dimension from the cube and add it back in. But that is very error prone since I lose any specific settings at the cube dimension level not to mention aggregations no longer include the dimension, etc.

Not seeing an alternative, I went through each measure group (I have 7) and changed the key columns manually in the XMLA and saved the cube. This worked, but I don't understand why BIDS automatically doesn't do it.

Is this a flaw in the BIDS or I should be missing something.

thanks
MJ

I've got a package which reads a text file into a table and updates another. I set up configurations so that I could import it into the SSIS store on both my dev and live servers. Now, I'm getting this error. I tried removing the configs and am still getting it.

I've been through each step and everything looks okay. Does anyone have any idea (a) what's wrong, (b) how to localise the error or (c) get any additional information? Or do I just have to recreate the package from scratch?

Using T-SQL REPLACE (or XML) To Add An Attribute To Every Other &&<td&&> Tag

Jan 10, 2008

I have the following as part of a stored procedure that generates an HTML report based on the data inserted into the table variable "@tblTemp":


SET @html =

N'<table border="1" width="0" style="font-family: Verdana, sans-serif;">' +

N'<tr><th>Name></th><th>ID</th></tr>' +

N'<col align="left"></col><col align="right"></col>' +

CAST ( ( SELECT td = [Name], '',

td = IDNumber

FROM @tblTemp

ORDER BY ID

FOR XML PATH('tr'), TYPE

) AS NVARCHAR(MAX) ) +

N'</table>' ;

SET @html = @html + N'<br /><br /><img src="muuscreenshot.jpg" width="452" height="507" alt="sample.aspx" />'

This generates a 2 column table that later in the stored procedure is sent out via sp_send_dbmail. The problem I'm having is that I want the right (2nd) column of the table to be right-aligned. For some reason, the line "

N'<col align="left"></col><col align="right"></col>' +" doesn't right-align the 2nd column when the report is sent through email (althought it does work if I take the generated string a use it to manually create an HTML file). So I want to add something like:

SET @html = REPLACE(@html, '<td', '<td align="right"')


but I still want the left column to be left-aligned, and this right-aligns everything. Is it possible for me to use REPLACE (or some other string function) to replace every other (alternating) "<td", or should I be looking at parsing this string using some 2005 XML features (unfortunately, using a CLR function to do this is not an option, since I am not allowed to turn that on on the server I'm using)? Thanks in advance.

How Can I Set An Attribute Of Unsigned Zerofill In SQL?

Aug 6, 2007

 How can I set an attribute of unsigned zerofill in SQL? Like for example, there is an option in MySQL phpmyadmin to set the attribute of a specific column to unsigned zerofill, it will be based on the length of the integer. For example, the lenght of my int is 5, so if i'll set the attribute of the column to unsigned zerofill, the value that will be auto incremented will have zeroes before that actual value, for example000010000200003....00010and so on and so forth...But, how can i do this in SQL? I'm using MS SQL Server Management Studio Express, but I can't find the field attributes to set it to unsigned zerofill.. I hope somebody will reply in this post.. :(

Representation For Heterogeneous Attribute Set

Jul 23, 2005

My company is working on a bond derivative portfolio analysis tool andwe're facing a problem that I did not see adequately addressed anywhere in literature. I really did RTFM. I'm very experienced inrelational modelling (10+ years) so this is not a case of notunderstanding the principles. Here is the problem stripped ofirrelevant context. The problem below is simplified for the sake of theexample so don't sweat the details.THE PROBLEM1. There are many types of bonds, each type has a different set ofattributes, different attribute names, different attribute datatypes.For example, bond A has two variables: a yearly interest rate anddate of issue, B has five variables: an interest rate and 4 specificdates on which various portions of principal need to be paid, bond Chas a set of 4 variables: interest rate in period 1, interest rate inperiod 2, the date on which the bond can be put back to the issuer,and two dates on which the bond can be called by the issue. And so on.So, on the first attempt I could represent each bond type as its owntable. For example,create table bond_type_a (rate INTEGER, issue_date DATE)create table bond_type_b (rate INTEGER, principle_date1 DATE,principle_date2 DATE, principle_date3 DATE, principle_date4 DATE)create table bond_type_c (rate1 INTEGER, rate2 INTEGER, put_date DATE,call_date DATE)This is the nice relational approach but it does not work because:2. There are many thousands of bond types thus we would have to havemany thousands of tables which is bad.3. The client needs to be able construct the bond types on the flythrough the UI and add it to the system. Obviously, it would be bad ifeach new type of bond created in the UI resulted in a new table.4. When a user loads the bond portfolio it needs to be very fast. Inthe table per type approach if a user has a 100 different types if bondin the portfolio you would have to do 100 joins. This is a heavilymulti user environment so it's a non-starter. It's impossibly slow.THE SOLUTIONSSo now that we ditched the table per bond type approach we can considerthe followiing solutions (unpleasant from the relational point ofview):1. Name-Value pairs.create table bonds (bond_id INTEGER, bond_type INTEGER, attribute_idINTEGER, value VARCHAR(255))Comment: The client does not like this approach because they want torun various kinds of reports and thus they doe not want the values tobe stored as VARCHAR. They want the DB to enforce the datatype.2. Typed Name-Value pairs.create table bonds (bond_id INTEGER, bond_type INTEGER, attribute_idINTEGER, int_val INTEGER, string_val VARCHAR(255), date_val DATE_Comment: The client does not like this because the table is sparse.Every row has two empty fields.3. Link table with table per data type.create table bonds (bond_id INTEGER)create table bond_int_data (bond_id INTEGER REFERENCES bonds(bond_id),value INTEGER)create table bond_string_data (bond_id INTEGER REFERENCESbonds(bond_id), value VARCHAR(255))create table bond_date_data (bond_id INTEGER REFERENCES bonds(bond_id),value DATE)Comment: This meets most of the requirements but it just looks ugly.4. Dynamic Mappingcreate table (bond_id INTEGER, int_val1 INTEGER, int_val2 INTEGER,date_val1 DATE, date_val2 DATE, string_val1 VARCHAR(255), string_val2VARCHAR(255))Then you have to add some dynamic mapping in your code which willprovide bond specific mapping (say, stored in an XML file). Forexample,For bond_A: yearly_rate maps to int_val1, issue_date maps to date_val1For bond_C: rate1 maps to int_val1, rate2 maps to int_val2, put_datemaps to date_val1, call_date maps to date_val2)Comment: This is very good for performance because when I load aportfolio of different bond types I can pull them all in in one SELECTstatement. However this approach has a problem that the table issparse. The number of fields of each type has to be as high as toaccmodate the most complex bond while simple bonds will only be usingtwo or three.THE QUESTIONS:Are the four approaches I described above exhaustive? Are there anyother that I overlooked?

Get Dicision Tree Attribute Name Using VB.net

Jul 10, 2007

Hello All,



I am going through the Data Mining Web Control sample and have that working beautifully. I now want to add in some more functionality by allowing the end user to select the: database, model and tree to view in the web viewer (similar to the parameters in SSRS). I am trying to figure out a way to get all this data programatically. So far this is what I have:




Code Snippet

For Each newDB As Microsoft.AnalysisServices.Database In myserver.Databases

dbName = newDB.Name.ToString

myLog.AppendText("DATABASE NAME - " + dbName + vbCrLf)

For Each newStructure As Microsoft.AnalysisServices.MiningStructure In newDB.MiningStructures

structureName = newStructure.Name.ToString

myLog.AppendText(" STRUCTURE NAME [ " + structureName + " ]" + vbCrLf)

For Each newModel As Microsoft.AnalysisServices.MiningModel In newStructure.MiningModels

modelName = newModel.ToString

modelAlgorithm = newModel.Algorithm.ToString

myLog.AppendText(" MODEL NAME -" + modelName + " " + modelAlgorithm + vbCrLf)



This works beautifully but I am having a problem getting the tree name which i believe its called the "attribute_name".



I can run the following SQL against Analysis Services and get the attribute name but I would like to get all this programatically and insert into a table.




Code Snippet

SELECT attribute_name

FROM [model].content

WHERE node_type=2



I plan to run this daily and update a table. This will ultimately let me pull the structure into my data mining viewer page. This way, I will only have to have one viewer page for all models, instead of a new page for each.



Thanks,

Cam

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:

Country
State-Province
City
Postcode

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

Geography.Geography.TheInvisibleLeafLevel.Members.Properties('Key')

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?

Continuous Attribute &&amp; Complexity_Penalty

Apr 27, 2007

I am having one question about discretization of continous attributes
values. How does it work? I need this information for my thesis. I have a
continous attribut, namely SKS, with range 0-20. When I use Microsoft
Decision Tree algorithm, this attribut split in SKS <= 18 and SKS > 18. I
want to know how does it find 18 as a number to split not the other.

One question again about Microsoft Decision Tree algorithm, about
Complexity_Penalty parameter. How does it affect the algorithm? For example,
if I set this value=0.1 what does it mean and how does it correspond with
growth tree?

Thanks a lot before for your kindness to answer my questions.. :-)
