PowerShell – Accessing Power BI Desktop Data and more…

November 18, 2018

Recently I got interested in getting data out of a Power BI Data Model to push into an SQL database.

On my way I discovered a lot of interesting techniques and Tools for Power BI Desktop.

1. First of all you need to know that Power BI Desktop actually is a small Web Server running an SSAS Mini Cube.

2. Next you need to prepare PowerShell to access the PBI Cube.

Solution :

In order to start you first need to start PBI Desktop and open a PBIX file you created before.

Once started you need to find out on which Random Port is was started.

There are 4 way to get the job done.

1. Install Dax Studio which you need to have, no question about this !

    Even if you are not using it for getting the Random Port…

Look in the bottom right corner :

2. Command line tool NETSTAT

   Run NETSTAT –b command and look for Power BI

image

In this case it was Port 60520

3. Look for the msmdsrv.port.txt file.

Once PBI is started it will create some folders and files.

You can find those here :

%LocalAppData%\Microsoft\Power BI Desktop\AnalysisServicesWorkspaces\

image

If you have multiple PBIX files open you will see more Random created subfolders.

Go to the random created folder and next to the Data Subfolder.

Open the msmdsrv.port.txt file to get the Port number.

4. Using the Tabular Editor

But it needs some dependent MS AS AMO Libraries

Now that you know how to get access to the Web Server Port.

PowerShell 32 Bit

You can now test PowerShell connection to the Power BI Desktop you have open.

But you first need a Connection String to be used in PowerShell

FIRST USE the 32 Bit PowerShell if you are using a 32 Bit Office installation.

Later in this post I will explain how to get it running in a 64Bit PS even if you have a 32 Bit Office installed.

I suggest that you use EXCEL for this to copy and paste it Winking smile

Go to Data and choose From Analysis Services.

Follow these steps :

Copy it from here :

You can also get the Catalog GUID from the folder name where you could find the Port number.

Run this PowerShell Script, it uses a DMV Query to get hold of the PBI Cube Properties

CLS

$Port = "60520"
$Catalog = "cff5b9a8-2f87-416c-97fd-8eccd5962d51"

$Query = 'Select * from $SYSTEM.DISCOVER_PROPERTIES'

$connectionString = "Provider=MSOLAP;Integrated Security=SSPI;Persist Security Info=True;Data Source=localhost:$Port;Initial Catalog=$Catalog"
 
$connection = New-Object -TypeName System.Data.OleDb.OleDbConnection

$connection.ConnectionString = $connectionString
$command = $connection.CreateCommand()
$command.CommandText = $query
$adapter = New-Object -TypeName System.Data.OleDb.OleDbDataAdapter $command
$dataset = New-Object -TypeName System.Data.DataSet
$adapter.Fill($dataset)

$dataset.Tables[0] | Format-Table # export-csv $filename -notypeinformation
   
$connection.Close() 

image

To list data from a Table use the EVALUATE command

$Query = 'EVALUATE Tickets'

image


PowerShell 64 Bit

If you are running a 32 Bit Office, you need to install the OLAP Drivers for 64 bit

(will be done when you install DAX Studio).

Or manually register the MSOLAP.DLL from the Power BI install folder.

Tools :

Power Pivot :

You can connect to a Power BI Desktop model using Power Pivot for example.

image

image

Dax Studio :

You can run commands directly against your Power BI Desktop.

Use DAX Commands

image

Or use a DMV Query.

PowerBI – Number and Currency Formatting

October 31, 2017

After looking for a solution why my Number Formatting did not want to work out…

After creating a new Measure it returned the classing US based formatting.

image

While I wanted to have the EU formatting in my table.

Power BI Desktop Client Regional Setting :

Even after changing the Power BI Desktop Client settings, it did not take effect Sad smile

image

Solutions :

Go to Control Panel –> Region –> FORMAT

image

If this format is not in line with your region it will overrule the Power BI Regional settings ?

image

So after applying the correct region format settings on OS level, everything appeared as expected Smile

PS : These figures are just demo based Winking smile

Enjoy!


PowerBI – Access SharePoint list data

February 5, 2017

As I showed in a previous post SharePoint is different Interfaces you can use to access as a data source.

https://audministrator.wordpress.com/2015/01/26/sharepoint-interfaces/

So I we know it can expose it’s List data using the  REST or oData protocol.

Open PowerBI and go to GET DATA menu.

Choose OData Feed to connect to your SharePoint data source

 

image

Once logged you can choose from your lists

 

image

And play around to make your data visible using all the features from PowerBI Smile

image

Once Finished you can publish your result

 

image

Once published you can reach out on the mobile apps.
