Model Generation From SSAS Cube And Perspective Problem

Jan 14, 2008



Hi,


I have built two perspectives in a cube. Let's say: Sales and Projects. When I open my cube in Excel 2007 and I choose to open the perspective 'Sales' I see all sales related dimensions and attributes. When I open the perspective Projects I see all projects related dimensions and attributes.
So far so good...

But now I generated a report model from the cube. When I start reportbuilder I can choose between three perspectives, because the total cube is added as an perspective as well. Looks pretty good, and now I open the sales perspective, but...

I see al the entities in the model, even the ones from the 'projects' perspective! It doesn't have all the functionality though, but it is visible with all the entritbutes.

I hope somebody knows the solution to this problem. Thanks in advance.

Report Model Accessing SSAS Cube In SSRS Sharepoint Integrated Mode----- Perspective ID Error

Dec 11, 2007

Hi,

I am receiving the following error when I run the report builder query. I am able to successfully select the dimensions and measures that I am intrested in but when I run the report I get the error message.

The 'PerspectiveID' custom property for the 'query' perspective is either not set or is not set to the string data type.
----------------------------
Semantic query execution failed.
----------------------------
Query execution failed for data set 'dataSet'.
----------------------------
An error has occurred during report processing.

I am testing this against both Adventureworks standard and enterprise cubes. Additionality I saw a post in this forum
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=368962&SiteID=1
that seemed related but I am using reporting services in sharepoint integrated mode so I am having a hard time trying to troubleshoot this.

Thanks,
Larry

Analysis :: SSAS Model Where Never Need Cube To Be Offline

May 21, 2015

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.

Mar 21, 2007

I am trying to add a calculated field / column in Report Builder when working with a Report Model built from anAnalysis Services Cube. I can create the calculated Field/Columns, but I get an error whenever I try to use it in a report.

Is there a way to create a report builder calculated column on report models built from a SSAS cube? Is this supported?

Analysis :: Adding KPI To SSAS Tabular Perspective

Aug 1, 2012

SQL Server Data Tools within VS 2010 Shell.2012 SASS in Tabular Mode.I've created a Measure and KPI in my fact table.  I've created a perspective named "Summary"  When selecting the fields and measures for display in the perspective, the measure is available, but not the KPI (target, status, etc.). When Analyzing in Excel with the Summary perspective, the KPI is not available in the field list. When analyzing in Excel with the (default) perspective, the KPI is available.As far as I can tell, there is no way to select a KPI within the perspective window.

Report Server Model Generation

Jan 28, 2008

I'm attempting to generate a model for our manufacturing database in Report Server. I can create the Data Source, but when I attempt to generate the model, I get several errors in the following format ...

More than one item in the Entity 'CUST ADDRESS' has the name 'COUNTRY'. Item names must be unique among immediate siblings. (DuplicateItemName) Get Online Help

More than one Field in the Entity 'CUST ADDRESS' has the name 'COUNTRY'. Field names must be unique within an Entity. (DuplicateFieldName) Get Online Help

There are several pairs of similar error messages (DuplicateItemName and DuplicateFieldName) listed.

The tables (i.e. CUST_ADDRESS) do contain the column name (i.e. COUNTRY) but are otherwise unremarkable.

Clicking the "Get Online Help" link leads to a page with an apology and no useful information.

The database is at Compatibility Level 80, but I am able to generate models for other databases at that level.
I've run DBCC CHECKDB against the database and it returns without errors.

This is on SQL Server 2005, Standard Edition x64 with SP2.

I'm at a loss for what to do next, there doesn't seem to be any documentation for this error available.

Thanks for any insight into this matter.

------------------------------------------------------------------------------------------

After some additional research, I've discovered that in the problem entities, i.e. "CUST ADDRESS", there is a column named "COUNTRY" and a separate column named "COUNTRY_ID". I tried renaming the COUNTRY_ID column in a test copy of the database and was then able to generate the data model in Reporting Services. The problem appears to be that the model generator is unable to differentiate between a column name "COUNTRY" with one named "COUNTRY_ID".

However, I cannot do this to my production database. Is there any fixes or workarounds in Reporting Services to handle this type of situation?

Report Builder Model Generation - How To Create A Key Attribute Along With The Role?

Mar 28, 2007

Hi,



I have found that in the autogenerated model attributes are missing for those fields that have relations to other tables. At first, it may look reasonable since a user can still get down to the field's value through the relation/related table. However, if the relation's key fields is the only thing the user wants to display, then going down to the related table is an overkill.

I can add an attribute manually and bind it to the key field(s). Is there an option in the autogeneration process to do it automatically? The only post I've found so far suggests to do everything manually (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1152575&SiteID=1). Is this the only way?



Thank you,

Leonid

SSAS: Processing Cube Hangs

Aug 4, 2006

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

Client Able To Access SSAS Cube Only Once

Sep 6, 2007

I have an excel workbook, that has a pivot table in it where the data source is an OLAP cube. My problem occurs on the client machine, logged in as the client. I remote into the PC, and create a pivot table using the OLAP cube connection. I create the pivot table and everything works fine - I am able to browse the data with no issues. Once I exit the Excel Workbook, and come back in - I am no longer able to connect to the datasource. I have tried both saving the password in the connection and not saving it. It has made no difference.

Dynamically Add Partitions To A SSAS Cube

May 9, 2007

The environment here is SSIS ETL feeding a Fact Table. The Fact Table is pulled into SSAS as a cube and reporting services are handled there. I am on the ETL side and don't pretend to know all the processing that happens with cubes, etc.



What we are trying to accomplish is to add partitions to a Cube via the ETL processing. The partitions should be incremented by Day, i.e. 20070501, 20070502, etc.



This is currently processed manually by the Reporting developer and we are looking for an automated process to reduce errors and hand work.



I have explored the following objects: Partition Processing DataFlow Destination and did not find much documentation or examples on it's use. If you have any information on this stage, please reply with such.



The other option is the Analysis Services Processing Control Flow. I understand that we can process Analysis Server objects as part of our package. Is there a way to incorporate a Partitioning Script in this object? If so, how. Again, I did not find detailed examples on the use of this object.



If you have experience with either of these, please feel free to reply. I appreciate any and all comments.

Analysis :: Count Distinct In SSAS Cube?

Sep 8, 2015

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?

Accessing SSAS Cube From Report Manager Error

Hey Forum Community

I seem to have a problem creating a model for my AS cube through Report Manager.

I have tried searching the forums and cannot find anything really helpful. I have had one cube setup and a model generated before and all was workin, but i had to delete it and i recreated the SSAS cube from scratch.

My user account has admin rights on the cube and also on the servers.

Client is Windows XP.

Any one got anythoughts on this or how i can determine what is wrong.?

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?

SQL 2012 :: SSIS Processing Of SSAS Multidimensional Cube Fails?

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.

Analysis :: SSAS - Roles With Read Definition Access Are Not Able To See Data In Cube

Nov 25, 2015

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.

How To Load SSAS Cube Partitions With Dynamic Name Directly From Flat Files

Feb 1, 2008

HI,

As the source data of the cube is from MySQL, and the source data volume is more than 80M row per month, I have to build multiple partition in the cube, each partition contain only one month data, even though, the time to load data directly from MySQL is still too long, and because the mysql .Net provider and is not mature enough, the connection often break while loading, so I have to try to load from flat file which was exported from MySQL.
The Partition Processing Destination seems support this way, but, even it shows the partition name in component editor, it actually process the partition with partition ID, and there's not any way to change destination partition name for this component.
Unless I have to change the SSIS package every month, looks like it is impossible to make a smart ETL program that can dynamic create new partition with the ID and name as YYYYMM every month and load data directly from the flat csv file exported from big MySQL table.


Does anyone know how to load data from flat text, and also support dynamic destination partition name?

And I also find a bug in Partition Processing Destination, even 2005 SP2, if there's more than one cube in a SSAS database, and if two partition name in different cube is same, in component Editor, you can not set mapping to the second one with the same name, even you point to the second one, and click ok, the next time you open the editor, you will find it high light at the first one. And even it shows name in editor, it actually process with partition ID instead of partition name, this make it is not possible by change the partition name which need to process to a constant name, say currentMonth to force the component process it.

Thanks.
