Connect to Power BI Desktop Model from Excel and SSMS

Power BI Desktop Excel SSMSPower BI Desktop is a fantastic report authoring tool. I have lots of experience working with Tableau as well and I can say, man, Power BI is growing very quickly. Lots of awesome ideas have been added to Power BI and a lot more is coming. But, It might be a question for some of you that is that possible to connect to a Power BI Desktop model from Excel, SQL Server Management Studio (SSMS) or SQL Server Profiler? The answer is yes, you can. But, how on earth someone should connect to a Power BI Desktop model from Excel, SSMS or SQL Server Profiler? Well, it could be useful for the following scenarios:

  • Connecting to the model using SQL Server Profiler for performance tuning, monitoring and so forth
  • Again, if you have some performance issues you might need to connect to the model from SSMS
  • You have a complex model and it’s hard for you understand it, but, you are a great Excel developer, so you can connect to Power BI Desktop model from Excel so you can use reach features available in Excel like named sets
  • Just for curiosity! You are curious about writing MDX codes over an existing model, you want to see how your model look like in Excel and so forth

In this article I show you how to connect to Power BI Desktop model regardless of any use case scenarios. So for whatever reason you’d like to connect to a Power BI Desktop model this post will help you achieve your goal.

How it works

Power BI Desktop uses xVelocity technology and loads data into memory. It uses a local instance of SQL Server Analysis Services (SSAS). It does the job by running msmdsrv.exe file which can be found in “bin” folder under your Power BI Desktop installation folder which is normally under you Program Files. The msmdsrv.exe is indeed the SSAS service file. So even if you haven’t installed SSAS on your machine Power BI Desktop runs msmdsrv.exe. When Power BI Desktop runs msmdsrv.exe it creates a local instance of SSAS. This local SSAS instance uses a random port number so it would be valid until Power BI Desktop is not closed or the msmdsrv.exe is not killed from Task Manager.

Find msmdsrv.exe in Power BI Desktop Folder

So, we have a local instance of SSAS using a random port number. Therefore, we should be able to connect to the instance from Excel, SSMS or SQL Server Profiler only if we know the port number.

Note: If you have installed an instance of SSAS on your machine you can find msmdsrv.exe under “\OLAP\bin” folder from SQL Server installation path:

%ProgramFiles%\Microsoft SQL Server\msasXX.INSTANCE_NAME\OLAP\bin

which XX is your version of SQL Server. So XX would be 10, for SQL Server 2008R2, could be 11 for SQL Server 2012 and so on. The difference between the local msmdsrv.exe file located in your Power BI Desktop\bin folder with the other one you can find under your SQL Server installation folder is that the one which Power BI Desktop runs is a console programme while the other one is a Windows service programme.

How to find Power BI Desktop local port?

There are various methods you can obtain the port number. In this post I explain three of them.

  • Finding Power BI Desktop local port using Windows Command Prompt (CMD)
  • Using DAX Studio
  • Finding local port number from Power BI Desktop temp directory

Power BI Enterprise Gateway, Everything You Need to Know

On-premises Data Gateway (aka Power BI Enterprise Gateway) is release a while ago (2 Dec. 2015), but, with the latest release on 22 Dec. 2015 Power BI Enterprise Gateway now supports live connections to both SQL Server Analysis Services Multidimensional and Tabular models as well as SAP HANA. In this post I’ll explain lots of important aspects of the Power BI Enterprise Gateway including installation,  configuration for different data sources including SSAS Multidimensional, Tabular and SQL Server Database and much more. If you need to have the lowest possible latency then you need DirectQuery/Explore Live feature on top of your on-premises data sources. The good news is that Power BI Enterprise Gateway now supports all following data sources:

  • SQL Server Database
  • SQL Server Analysis Services Multidimensional
  • SQL Server Analysis Services Tabular
  • SAP HANA

    In this article you’ll learn how to install and configure Power BI Enterprise Gate Way, how to manage different live data sources, how to create reports on top of live data sources and more.

  • Note 1: If you want to use DirectQuery to connect to your on-prem SQL Server Database OR Explore Live your SQL Server Analysis Services Tabular model then you might not need to install and use the Power BI Enterprise Gateway. In those cases you can install Power BI Personal Gateway to connect to an instance of SQL Server OR install Power BI Analysis Services Connector to connect to your on-prem instance of SQL Server Analysis Services Tabular model rather than installing the Power BI Enterprise Gateway. But, bear in mind that selecting the best gateway is really depending on your use cases, your data sources and the environment you’re working on.

  • Note 2: The Power BI Enterprise Gateway and Power BI Personal Gateway CAN be installed on the same machine.

    Downloading and Installing Power BI Enterprise Gateway

    You can download the gateway from the dedicated download page for On-premises Data Gateway on Microsoft website or after logging into Power BI Service with your account, click on “Data  Gateway” from the download menu:
    downloading on-premises data gateway from Power BI service

    OR you can go straight to the gateway page then download the Power BI Gateway – Enterprise (Preview):

Browsing Cubes Remotely from Excel Trough a VPN Connection without Using Windows Authentication

Technically when you connect to another network through a VPN connection you can see all allowed machines on that network. So it is easy to connect to a SQL Server instance using SQL Server authentication. However, I’m explaining this part for some of you guys that might be new to connecting from Excel directly to a database on SQL Server and create flashy reports on Excel.

But, what about connecting directly from Excel to a remote Analysis Services instance without using Windows Authentication? You’re right! I’m saying you can connect directly from your own Excel to a remote SSAS server without using windows authentication. Well, technically there is no SQL Server Authentication mode available for Analysis Services. So what does that actually mean when I say “without using windows authentication”? If you’re interested in finding the answer keep reading this article.

Scenario:

You’re working as a BI consultant, you’ve been told that a client needs to have some simple reports on Excel as follows:

·         You should connect to the client’s server using a provided VPN connection

·         The VPN connection could be established through a Windows VPN, Cisco VPN etc. so the VPN client or the port and protocol used don’t actually matter

·         Microsoft Excel is NOT installed on the client’s server

·         You’re NOT allowed to install Excel on the server

·         As it is a costly process the client will not setup a virtual machine in their network so that you can remotely connect to it and install Excel then connect to their SQL Server/Analysis Services instances

·         There is no trust relationship between your network and the client’s network, so your domain user name and password could not be authenticated on the client’s network

·         The client needs to have some reports on Excel on top of a SQL Server database and OLAP cubes on Analysis Services (SSAS)

·         You have the right to run an application as administrator on the remote server

·         You need to connect to the remote server directly from your own Microsoft Excel installed on your machine

·         The client also provided a remote desktop access to the server

·         On the remote desktop SQL Server Management Studio (SSMS) is installed

·         In the remote SQL Server your account is a member of the “securityadmin” server role so you can create a new SQL Server Login
