Power Pivot & Power Query

I have very recently purchased yet another copy of Office, I now have every version from 97-2013, all Pro versions. I downloaded powerpivot for 2010 and that works fine. When I purchased (directly from MS) 2013 I thought powerpivot came with it as standard.
I am agahst that it doesn't, I tried downloading it only to be told "I do not have the correct version"!!!
What is going on MS?? nowhere does it say "CAUTION this Pro version does not have PowerPivot or PowerQuery, oh and what's more you can't download it either!"
I am a developer who constantly hears from clients "I'm not having 2013..." maybe they know more than I do eh?
Come on please play fair!

Hi,
Which Office 2013 version are you purchased? Office 2013 Professional or Office 2013 Professional Plus? As far as I know, Power Pivot & Power Query
are available in the Office 2013 Professional Plus and Office 365 Professional Plus editions, and in the standalone edition of Excel 2013, not Pro version( If you only purchased Pro, you can't use them)
Now Power Pivot is built-in add-ins with Excel 2013, we do not need to download it, just enable it.
Go to File > Options > Add-Ins.
In the Manage box, click COM Add-ins>
Go.
Check the Microsoft Office Power Pivot in Microsoft Excel 2013 box, and then click
OK.

Power BI - Office 365 data storage for Excel (Power Pivot & Power Query) architecture

Hi, I trying to find a comprehensive view of the Power BI architecture, specifically where the data for Power Pivot & Power Query files are held. I've seen reference to the Vertipaq Engine and the data being stored in the Excel File, however this is
in reference to 2010.
Other references I've seen (SharePoint on premise with Power Pivot) have shown me that the data held in the Excel files on the SharePoint sites are actually held in SQL Server instances.
Could anyone provide clarity on the architecture for Power BI please...
Tim
Thank you for you time folks!

Hi Tim,
let my try to explain this:
When you load data into Power Pivot it is actually loaded into Vertipaq (in-memory column-store) and it resides there until you close Excel. Technically speaking Power Pivot is a single-user SQL Server Analysis Services instance hosted within Excel. When you
close Excel a backup of the Power Pivot "database" is created and stored within the resulting .xlsx-file .
Any user that has access to the Excel file also has access to the Power Pivot model, so there is actually no security
This is very similar to any other excel file
Once the Excel is stored in SharePoint / SharePointOnline and is access the first time the backup that is stored within the Excel is restored into SQL Server Analysis Services instance running in SharePoint Integrate mode
all connections to the Excel-File are redirected to that SSAS instance. After some time of inactivity the model is unloaded from that SSAS instance again to free up the memory
the data itself so basically always resides inside Power Pivot or respectively the Excel file
Power Query only stores the actual query (= M-script) but no data

User Based Security in Power BI (Power Pivot / Power View)

I am looking for a way to implement User based security (based on user access needs to restrict data) for my Power BI reports. Is there any way implement this kind of security. We have this support in traditional OLAP cube by creating roles and manage them
at different dimensional data.
Any help would be highly appreciated.

Hello,
You want to implement this functionality using the Power BI Preview or using the Power BI reports integrated in an application?

Excel 2013 Standalone - Power Pivot Plug-in not visible or available for activation

Dear Microsoft Team
According to your blog, the Excel 2013 standalone SKUs have now been updated to include Power Pivot and Power View. (follow this link: http://blogs.technet.com/b/the_microsoft_excel_support_team_blog/archive/2013/02/27/unable-to-use-excel-2010-powerpivot-workbooks-in-excel-2013.aspx)
I've just bought Excel 2013 standalone (non-commercial, SKU AAA-01350) from the MS Store and cannot see either Power Pivot or Power View among the list of the COM Add-ins available. The corresponding sections don't appear in the Excel ribbon.
Are you aware of any glitches in the Office 2013 installation logic that might have caused such a problem? My PC runs Windows 8 (32-bit), with both Office 2010 and Excel 2013 Standalone installed.
Thanks
Svviss

Hi Ron
Thanks for your prompt reply. Unfortunately, that didn't make much difference. I had a dialog shown to me reading the following:
Update for Microsoft Excel 2013 (KB2817425): There are no products affected by this package installed on this system.
I've since done some digging around and there seem to be other accounts of the newly updated Excel 2013 Standalone not installing Power Pivot. Here is the link (scroll all the way down, to the most recent comments):
http://www.powerpivotpro.com/2013/08/power-pivot-power-view-now-available-in-2013/
Any other ideas or workarounds?

Data loaded to Power Pivot via Power Query is not yet supported in SSAS Tabular Cube

Hello, I'm trying to create a SSAS Tabular cube from a data loaded to Power Pivot via Power Query (SAP BOBJ connector) but looks like is not yet supported.
Any one tried this before? any workaround that make sense?
The final goal is pull data from SAP BW, BO Universe (using PowerQuery) and be able to create a SSAS Tabular cube.
Thanks in advance
Sebastian

Sebastian,
Depending on the size of the data from Analysis Services, one work around could be to import the data into into Excel and then make an Excel table and then use the Excel table as a data source.

Why some columns are not read into Power Pivot when reading data from a SQL query

I have this SQL query that I want to use to read data to PowerPivot from:
SELECT Score.FieldCount as fieldcount, Score.Record.GetAt(0) as predicted_gender, Score.Record.GetAt(1) as probability_of_gender, Score.Record.GetAt(2)
as probability_of_m,
Score.Record.GetAt(3) as probability_of_f, Score.Record.GetAt(4) as customerkey
FROM
SELECT * FROM dbo.myCLR1(
dbo.MyCLR2('c:\fILES\MLSM.xml'),
'SELECT * FROM [dbo].[Customer]') Input
) Score
After I click 'Finish' in "Table Import Wizard", I can only get 1 column (FieldCount) in Power Pivot window. Why don't I get the other 4 columns? If I save the result to a table I do get all columns but my goal is to dynamically present the result
so that's not an option. Can anyone shed some light?
Thanks,
Chu

If I only pass in query as
SELECT * FROM dbo.myCLR1(
dbo.MyCLR2('c:\fILES\MLSM.xml'),
'SELECT * FROM [dbo].[Customer]') Input
I do get 2 columns (FieldCount and Record as shown below)

Power Query; How do I reference a Power Pivot table from a Power Query query

Hi,
It's pretty awesome how you can define Extract Transform and Load processes within Power Query without having to type in a single line of code. However how do I reference a Power Pivot table from a Power Query query to avoid me repeatedly accessing
the same data source (CSV) file with a view to increasing performance?
We are aware of the reference sub menu option with Power Query. However the new query created by the "reference" option still seems to refresh data from the data source (CSV) rather than just referencing the base query. Is this understanding
correct? There does seem to be a lot of hard disk activity when re-running the new query which is based on a base query rather than a data source. So we were hoping the new query would just need to reference the base query in memory rather than rescanning
the hard disk. Is there any way to ensure that the reference query just rescans the base query in memory?
Kind Regards,
Kieran.
Kieran Patrick Wood http://www.innovativebusinessintelligence.com http://uk.linkedin.com/in/kieranpatrickwood http://kieranwood.wordpress.com/

Hi Kieran,
This sounds like something to be suggested for a future release. At the present time, Power Query will always re-run the entire Power Query query when refreshed. The Reference feature is analogous to a SQL view whereby the underlying query is always re-executed
when it's queried, or in this case refreshed. Even something like using the Power Query cache to minimise the amount of data re-read from the disk would be helpful for performance but the cache is only used for the preview data and stored locally.
It would be a good idea to suggest this feature to the Power BI team via the feedback smiley face.

Power Pivot Bug: Can't Save Edits to Power Pivot Query without checking Teradata Connection's "Save my password" Option

Can't edit and re-Save Power Pivot query with Teradata connection (using LDAP security mechanism) unless "Save my password" option was checked. Without this option I receive this error upon attempt to Save changes made to the query ...
The following exception occurred while the managed IDbConnection interface was being used: [TeraGSS Security Library] [115022] Exception occurred in TERAGSS layer. See inner exception for details.;TdgssAuthenticationTokenExchange delegate threw an exception.
See the inner exception for details.
ErrorCode: -452984642 Severity: Error Facility: DotNet
[Teradata Database] [8017] The UserId, Password or Account is invalid..
A connection could not be made to the data source with the DataSourceID of '6a06124c-496f-4887-bf39-d2582173d499', Name of 'Teradata fsltdprd'.
An error occurred while processing table 'Query'.
The current operation was cancelled because another operation in the transaction failed.

Sorry you're right, the Office category isn't currently accepting bug reports in which case Olaf's suggestion to use the smiley face is the way to go. In Excel please go to File > Options > Trust Centre > 'Trust Centre Settings...' and check
that the Feeeback Tool is enabled.
If the option is greyed out like this...
... then you should be able to enable it by changing the value of the 'Enabled' registry key from a 0 to a 1 which you will find under: HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\Feedback. You will then need to close all Office applications
and re-launch Excel 2013.
Once the Feeback Tool has been enabled, you should see the smile face(s) in the top right hand corner of the Excel window and be able to send your feedback.

Michael

Blank Record Appearing in Power Pivot, How do I ensure that my Power Query script is filtering out all the Blank Records

Hi,
I noticed once of my Fact tables in my Power Pivot model contains a blank record. I can't understand why.
So I added a Filter expression to the underlying Power Query query, something like; -
Text.Length("MyField") > 0
However after refreshing the Power Query query which contains the above expression the blank record still appears within my Power Pivot table.
Kind Regards,
Kieran.
Kieran Patrick Wood http://www.innovativebusinessintelligence.com http://uk.linkedin.com/in/kieranpatrickwood http://kieranwood.wordpress.com/

hi..
As my understand, the blank record in Power Query will be return null value . So that, You try to use Text.Length("MyField" ) <> null.

Does SharePoint 2013 have Power Query services similar to Power Pivot and Power View?

Does SharePoint 2013 include services to host/support Power Query content similar to the way it hosts Power Pivot content in the Power Pivot Gallery?

Miguel. Is there an update to this? New information or new timeline?
We have SP 2013 Enterprise, on-prem. I'm finding that Power Query 's ability to get CSV or XML or other Web Services content, and then load it up to PowerPivot, is a way to address the lack of ODATA connectivity options on the web. :-(
I would very much like to be able to create an XLS doc, with a Power Query to a CSV file, Loaded to PowerPivot, and have SP's Excel Services/PowerPivot engine continue to update the content for me. It fails today, as you stated above.
Do you even think this will be updated for the on-prem version of SharePoint 2013 or will it only live in Power BI for Office 365?

The Power Query ribbon and the Power Pivot ribbon are gone !

Hello,
I created in Excel 2013, using Power Query, two large tables (more than 4 000 000 rows) according this principle: << However,
the query pane that shows up on the side while data is loading lets you disable "load to worksheet". The data will continue to download. Once the download is done, you can click on "Load to Data Model" which will then get the data into
the underlying xVelocity/data model.>>
I built two calculated columns in order to create PRimary and Foreign keys for relations.
I saved the xlsx file several times
I Closed the xlsx file
I reopened the xlsx file but, bad news, the
Power Query ribbon and the Power Pivot ribbon are gone !
I can check the the data connections are still there.
What happened? What did I miss ?
Thanks for your help
Error message when I refresh connections :

When I restart the computer, Power
Query and Power
Pivot ribbons come back. But if I enter a
formula, they go away again.
What could be the solution?

Can I update datas of Power Query after making relation tables in Power Pivot ?

Can I update datas of Power Query after making relation tables in Power Pivot ?
I want to update datas at day by day to viewing today's graph by Power View on Excel.
Power Query use to transform web site to Power Pivot data model table.
Power Pivot use to making relasing tables, and making measuers.
Regards,
Yoshihiro Kawabata.

Hi Yoshihiro,
Can you share an example of the things you are doing in Power Pivot? There are some operations that prevent the query from being refreshed in Power Query; this is not ideal so we are currently working on fixing it.
Thanks for your feedback.

Transform power pivot model to query

hi eb
after building a power pivot model which includes a number of related tables
i realized i want to analyze results in a simple table not in pivot tables
there for my model should result to one table of records.
So i guess i need to start with a single query which will return a single results table.
Can i transform my original model to free sql to be used as my data source?
TIA!
Rea

In Excel 2013 you can do this:
click ribbon Data / Existing Connections
click tab Tables
select one of the tables of your PowerPivot model (not the Workbook Data Model at the beginning of the list)
click Open
In the Import Data dialog box, confirm you want to import a Table and click OK
Right-click any of the cells of the table and select Table / Edit DAX menu
In the Edit DAX dialog box change Command Type to DAX, the write the DAX query you want in the Expression text box, then click OK
Of course, in order to write the DAX query I suggest you using a better editor such as DAX Studio (more info here:
http://www.sqlbi.com/tools/dax-studio).

Unable to load the tables in the Power Pivot Window – An Item with the Same Key has already been added

Hi there,
I recently had the following situation, where I changed the source of my CSV file in Power Query.
Once I had reloaded the file, it would then not load into Power Pivot. So I disabled the loading from Power Query into Power Pivot. I then enabled the loading to the Data Model. Which then successfully loaded the data into Power Pivot.
But once I went into Power Pivot, had a look, then saved the Excel file. Once saved I closed the Excel file. I then opened the Excel file again and all the sheets that interact with the Power Pivot data work fine.
But if I go and open Power Pivot I get the following error: Unable to load the tables in the Power Pivot Window – An Item with the Same Key has already been added.
This is what I get from the Call Stack
at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
at Microsoft.AnalysisServices.Common.LinguisticModeling.SynonymModel.AddSynonymCollection(DataModelingColumn column, SynonymCollection synonyms)
at Microsoft.AnalysisServices.Common.LinguisticModeling.LinguisticSchemaLoader.DeserializeSynonymModelFromSchema()
at Microsoft.AnalysisServices.Common.SandboxEditor.LoadLinguisticDesignerState()
at Microsoft.AnalysisServices.Common.SandboxEditor.set_Sandbox(DataModelingSandbox value)
at Microsoft.AnalysisServices.XLHost.Modeler.ClientWindow.RefreshClientWindow(String tableName)
I would assume that the issue is with the synonyms and for some reason, when I disabled the loading of my data into the Power Pivot Model, it did not remove the associations to the actual table and synonyms.
If I renamed the table in Power Pivot it all works fine. So that was my work around. Fortunately I did have a copy of the Excel workbook before I made this change. So I could then go and add back in all the relevant data to my table.
Has anyone had this before and know how to fix it?

Hi there
I can share the work book, if possible to send me an email address. As the workbook size is about 9Mb.
Thanks
Gilbert
