Microsoft Lists debuted in 2020 and they are a (yet another) great way to organize list-based data. Now, when someone says data, I think Power BI. Obviously, we’ll want to report on this data, but how do we do that? There is no Power BI connector for Microsoft Lists. The answer is quite simple, if not completely obvious. You need to use the SharePoint Online List connector in Power BI.
Microsoft Lists are the same thing as SharePoint lists. In fact, they ARE SharePoint lists. The Microsoft Lists service is just a new user interface for interacting with them. You can use Lists all you want and never see SharePoint at all, unless you need to change list settings, but I digress. Given this fact, as far as Power BI is concerned, everything that applies to SharePoint lists applies to Microsoft Lists lists (the grammar here gets awfully awkward).
For reference, I wrote a series of articles some time ago about the idiosyncrasies of working with SharePoint data in Power BI, and these articles are still valid today (2021). The most recent of these articles can be found here and includes links to the others.
There is one thing that is worth mentioning about Microsoft Lists. When a new list is created using the Lists interface, the user can save it to any of their SharePoint sites, but another option is to same it to “My lists”.
When you use the SharePoint Online list connector in SharePoint, it prompts you to enter the URL for the SharePoint site that contains the list that you want to report on. That is straightforward when your list is stored in a SharePoint site, but what if your list is stored in “My lists”? Where are “My lists” stored?
They are stored in a “personal” SharePoint site. We SharePoint old timers would know it as the MySite, and while usage of MySite has been de-emphasized in Microsoft 365, it is very much still there. Each user has one. In fact, this is where the “personal” OneDrive for Business content is stored – in the Documents library of the very same MySite. By storing personal lists in the MySite, Microsoft Lists is just following the same pattern used by OneDrive for Business, which makes perfect sense.
Given this, what URL should you use in Power BI to connect to your lists stored in “My Lists”? You’ll find it in the Microsoft Lists web interface in the URL bar. It’s that portion of the URL up to “/Lists/.
Power BI is without question the best way to report on data in SharePoint lists. The query tools available in Power Query make working with SharePoint data relatively painless, an the cached dataset means that reports are run against an optimized copy of the list data, not the data itself.
This latter distinction, while removing the performance issues of systems that query lists directly, also introduces problems with data latency. The report will never be fully “up to date”, as it needs to be refreshed on a periodic basis.
Consider the following scenario. A Power BI report has been built that uses data from a SharePoint list. That report has been embedded on a SharePoint page in the same site. A user adds an item to the list, and then navigates to the page to see the updated report. Unfortunately, that report won’t get updated until the next scheduled refresh.
This has been a significant problem, until the recent release of the new “Refresh a dataset” action in Microsoft Flow.
It is a relatively simple procedure to add a simple 1 step flow to any SharePoint list that is triggered when an item is created, updated, or deleted. This flow simply needs to add the “Refresh a dataset” action, that is configured for the relevant dataset, and these embedded reports will be updated very shortly after the data is modified.
Alternatively, the flow can be triggered by a timer, allowing you to create your own schedule (every 5 minutes, etc) that is not hardwired to run at the top or bottom of any given hour.
A few caveats should be kept in mind when using this action however.
While this action gives us much finer grained control over when refreshes happen, all of the current license restrictions remain in place. For datasets located in the shared capacity, only 8 refreshes per day are allowed.
For datasets in dedicated capacities (Premium), there are no limits to the number of refreshes. The limit of 48 per day is a UI restriction, not a licensing restriction. However, refresh can utilize significant resources, particularly memory, so you’ll want to ensure that you have significant resources to support the update frequency.
Finally, the load on the source data system should be considered. Refresh will pull a significant amount of data every time it is run.
Caveats aside, this new flow action is a welcome relief to those that need greater control of how their reports are updated.
Power BI V2 workspaces recently (May 2019) entered into general availability. The biggest difference between a V1 and V2 Power BI workspace is the fact that a V2 workspace is not backed by an Office 365 group, and a V1 workspace is. One area that this change affects a great deal is the “Get data” experience in the Power BI service (browser). This post outlines the differences, and describes the configuration options.
Data connections to files stored in SharePoint and OneDrive have certain unique characteristics when they are created in the browser. For example, these connections are automatically refreshed hourly unless that option is disabled.
V1 workspaces automatically offer the connection to the Documents library in the underlying SharePoint site. V2 workspaces do not automatically offer this option, as there is no underpinning SharePoint site. However, any V2 workspace can be connected to any Modern SharePoint site, and in this way, the option is more flexible. For the sake of clarity, a Modern SharePoint site is one that is backed by an Office 365 Group, and has an email address.
Let’s explore the 4 possible experiences when using “Get Data” and then choosing “Files” in the Power BI service. There are 4 possible experiences, depending on the type and configuration of the workspace;
V2 workspace not connected to a site
V2 workspace connected to a site
In each example below, the options are reached by selecting “Get Data” and then choosing “Files”. The type of files that can be imported are CSV, Excel, PBIX (Power BI Desktop files) and RDL (paginated reports).
The personal workspace is the only workspace available using the free Power BI license. It is not connected to any SharePoint sites, and provides 4 options for importing.
“Local File” can be used for importing files from a local file store. Files imported in this manner are not automatically refreshed, and without the use of a gateway, cannot be. This option is available for every workspace type and will not be discussed further. “Learn about importing files” is a simple help link, likewise available to all workspace types.
OneDrive – Business connects to the currently logged in user’s OneDrive for Business storage. This is the OneDrive that is associated with “School or Organization” account which is stored in Azure Active Directory.
OneDrive – Personal connects to a user’s personal, or consumer OneDrive account. This is the type of OneDrive that is accessed using a “personal” account (otherwise known as a Microsoft account, or MSA). The personal workspace is the only type of workspace that allows a connection to personal OneDrive content.
SharePoint – Team Sites allows files stored in any SharePoint Online library to be loaded. Files stored in SharePoint on-premises can be loaded into Power BI, but only through Power BI Desktop. This method is online only.
Data imported in this fashion will be updated hourly with the exception of “Local File”. This will also be true of any OneDrive or SharePoint source referenced below.
A Power BI V1 workspace is connected to an Office 365 Group, and therefore backed by a SharePoint site. This is reflected in the Files experience in the service.
Here we see 3 import options. Local File, SharePoint – Team Sites, and “Learn about..” are exactly the same as with personal workspaces. However, both OneDrive options from there are unavailable. The “OneDrive – XXXX” option is different, and bears some explanation.
In the image above, “Demos” is the name of the V1 workspace. Selecting this option will open the SharePoint library named “Documents” in the SharePoint site that is associated with this workspace and Office 365 group.
In my opinion, this option is poorly named, which leads to confusion. This container truly has nothing to do with OneDrive – it is a SharePoint library. We already have enough different “OneDrives” to keep track of, but I digress.
V2 workspace (not connected to a site)
The V2 workspace is not associated with a SharePoint site, and therefore, there is no Documents library to connect to. The option is instead replaced with the ability to connect to the user’s OneDrive for Business (OneDrive – Business) storage, as in the personal workspace. In essence, this experience is identical to the personal workspace experience minus the ability to connect to personal OneDrives.
V2 workspace (connected to a site)
Although a V2 workspace is not inherently connected to a SharePoint site, it can be manually connected to one. This restores the capability missing from V1 workspaces, while being more flexible. The workspace is no longer bound to a specific site, but can be configured to work with any Modern SharePoint site. In addition, the same site can be bound to multiple workspaces.
The “Modern” distinction above is important. The SharePoint site itself must be backed by an Office 365 group, as that is how it is identified in Power BI.
Associating a workspace with a SharePoint site
With V2 workspaces, site connection is now a property of the workspace. To edit workspace properties, select either the workspace settings button in the ribbon, or the ellipsis beside the workspace in the workspace list.
The connection setting is in the advanced section, and is identified as the “Workspace OneDrive”.
The important thing to note here is that you do NOT enter the URL of the SharePoint site in this field. This field is expecting the address of it in email format (ie email@example.com). All Modern Sharepoint sites are bound to an Office 365 group, and the email address is the address of that group.
Get Data – File options for a V2 connected site
Once connected, the “Get Data” – “File” options will be much the same as with an unconnected workspace, but with the “OneDrive – SiteName” option added.
I still take exception with the name presented above, in my opinion it should be “Site – SiteName” or “SharePoint – SiteName site” and use a SharePoint option. However, once connected files in the connected site can be imported easily into the Power BI service.
It is important to understand what the connected site is used for in Power BI. Connecting a site allows for files stored in a SharePoint library to be either imported into the service (all supported file types), or connected to (Excel files). This feature does NOT allow Power BI content to be stored in a SharePoint library
Reporting on SharePoint data has been a requirement for a long time, and there have been many approaches to fulfill this need. Custom web parts, Data View web parts and SSRS direct connected reports have historically been some of the solutions, but they all suffer from the same problem. If you have any serious amount of SharePoint data, you’ll quickly begin to bump into capacity limits and performance limitations, and in some cases, you can impact the performance of the overall system. In order to avoid this problem, it is necessary to warehouse SharePoint data first, as I argued in this post from 2012.
Once your list-based data is in a relational database, the performance issue is taken care of. However, the means of getting it moved there have traditionally been problematic. For a long time, there was a CodePlex project called the SharePoint List Source and Destination. This solution provided read and write access to SharePoint lists from SQL Server Integration Services (SSIS). Unfortunately, it was last updated in 2012, it was unsupported by Microsoft, and it did not support authentication for Office 365. This of course rendered it useless for use with SharePoint Online. In 2015, SQL Server Integration Services got an OData source, and given that SharePoint lists have OData endpoints, this became a viable option, particularly given that it did support Office 365 authentication. The OData connection from SharePoint did however have some limitations as well.
For cloud scenarios, Power BI has emerged as a very competent way of reporting against SharePoint data. It has native connectors for SharePoint list data, both on premises and in the cloud and Power BI reports can be hosted in the cloud through the SharePoint Power BI web part. On premises, the same can be done with Power BI Report Server. The structure of Power BI reports mean that the data is cached in a data model, so reports are not run directly against the list data source. This avoids the performance issues listed earlier.
Earlier this year I published a series of articles detailing how to do exactly this. The only issue with this approach is that the data shaping and preparation is always specific to a single report. If I have 5 different reports that use one list, I must query and shape that data 5 different times – one for each report. This is where Power BI dataflows come in.
In this context, dataflows are essentially a data warehousing layer with transformation capability. Instead of each report connecting back to a source list, the dataflow connects to the list, shapes the data with Power Query online and stores it in a data lake. The Power BI reports then connect to the dataflow as their data source. Transformation and storage only need to happen once.
As of this writing, dataflows are in public preview, so be warned – some things could change.
Creating a dataflow
Creating a dataflow from a SharePoint list is relatively straightforward. In our examples below, we will work with the same sample list from the series of articles on SharePoint data earlier this year. To begin open Power BI and navigate to a workspace (your personal workspace will not have dataflows). Click on the workspace name in the navigation pane and the dataflows tab should be available.
To create a new dataflow, Select the Create button, and click dataflow.
Select the Add new entities button and the data source selection will appear. SharePoint list and SharePoint online list are both options. SharePoint list is for on premises list data which will work with the On-Premises Data Gateway. In our case we are working with SharePoint Online, so we select the SharePoint Online source.
At this point, you enter the URL for the site that you want to connect to (NOT the URL for the list) and select the Next button. Power BI Will connect to the site and you can then select which list you want to work with. In our case, we need our Listings data, so we select that list and click Next.
Finally, we’re in the Power Query editing screen. This should be quite familiar to those used to working with Power Query in either Power BI Desktop or in Excel. From here you can select the columns that you want to include in the dataflow.
Although this experience is similar that building queries in the Power BI Desktop, there are a few noticeable differences. Queries in a PBIX file are referred to as queries, but within a dataflow they are referred to as entities. These entities can be custom, or they can be mapped to Common Data Model object types. The Power Query web editor also does not include the full featured editing ribbon found in Power BI Desktop, but instead has a button bar. Many of the editing options available in Power BI Desktop are not available in the Power Query web experience.
If you have read through some of my earlier articles on working with SharePoint data in Power BI, you will notice that there are fewer columns available than we see in the Desktop Power Query editor. Most notably for us working with SharePoint data is the FieldValuesAsText column which is the convenient way of retrieving the text representation of complex SharePoint list column types. At first glance, this would appear to be quite limiting.
However, by right-clicking on the entity name, we can access the Advanced Editor.
This Advanced editor allows you to write queries by hand using the M language. The side benefit of the Advanced editor is that it makes queries portable between platforms -Desktop, Excel, and now dataflows. You can therefore build your queries in Power BI Desktop using its fully functional editor and then copy and paste it into a new blank query in the dataflow editor. Using this approach allows you take advantage of the SharePoint helpers built into Power BI Desktop as the FieldValuesAsText column, and other columns are available. Using this technique, the Listings example can be transformed into several normalized tables in the dataflow.
Click on Done to save your entities, and then the Save button to save your dataflow. You will be prompted to Refresh Now which is a good idea because by default, the dataflow has no data contained within it. To keep the data up to date, you need to set a refresh schedule by clicking the schedule refresh icon under actions for the dataflow in question. From here, you schedule data refresh in the same manner as you would with ta Power BI Report.
Using the dataflow
Once data is loaded into the dataflow it becomes a source for a Power BI report. You must use Power BI Desktop to create this report, there is no way to connect a report to a dataflow in the pure web interface. Start Power BI Desktop and select “Get Data”. Choose the Power BI blade and then Power BI dataflows.
After clicking Connect, you will be presented with a set of Power BI workspaces that contain dataflows. Opening the workspace will allow you to open the dataflow and select the desired entities.
Once loaded, the report can be built just like any other. When it is refreshed, it will be refreshed from the data stored in the dataflow, NOT directly from the SharePoint list. It is therefore important to keep the dataflow itself up to date.
Any number of reports can be created from the dataflow. Instead of having all the transformation logic tied up within a single report, dataflows allow them to be centralized and consistent. With a little work, these transformations allow you work with your SharePoint data just as though it were relational. Power BI dataflows really are the best way to perform data warehousing with your SharePoint data, whether you SharePoint is on line or on-premises.
The recent availability of the SharePoint 2019 public preview, and the supporting information that accompanies it has clarified the status of Business Intelligence features in SharePoint 2019. This release, with one exception, is the culmination of the process of decoupling BI from SharePoint which began in SharePoint 2016 through the removal of Excel Services. This decoupling strategy was initially articulated in the fall of 2015 with the document Microsoft Business Intelligence – our reporting roadmap which stated that SQL Server Reporting Services was to be the cornerstone of their on-premises BI investment (and not SharePoint).
The embedded BI features now run with SharePoint as opposed to on SharePoint. These changes do however require some planning and some effort on behalf of those that have already invested in the current platform and wish to move forward on-premises. With this in mind, and the fact that concise information around these changes is a bit difficult to find, I wanted to put this reference together. This post does not get into migration strategies, only the changes themselves.
A summary of the changes to BI features, and a brief discussion of each is below.
SQL Server Reporting Services Integrated Mode
BISM file connections
PerformancePoint – Decomposition Trees
Power Pivot for SharePoint
Scheduled workbook data refresh
Workbook as a data source
PowerPivot management dashboard
SQL Server Reporting Services Integrated Mode
SSRS Integrated mode was deprecated in November 2016, as was not a part of SQL Server 2017. However, organizations could continue to use SSRS versions from 2016 and prior in SharePoint 2016. This is not supported in SharePoint 2019, which means that integrated mode isn’t an option at all with SharePoint 2019. The good news is that the recent Report Viewer web part fully replicates the capabilities of the SSRS Integrated mode web part.
Power View was a feature of SSRS Integrated mode and is available in Excel. When Excel Services was removed in 2016, Power View in Excel required SSRS Integrated mode to work. Both supporting platforms are now gone, and thus Power View is not supported in SharePoint 2019.
BISM file connections
The BISM file connection type was used by Excel and SSRS to connect Power View reports to SQL Server Analysis Services data sources. This connection type has been removed along with Power View.
PerformancePoint is a combination of capabilities that includes dashboarding, scorecards, and analytic reports. Very few new features have been added to PerformancePoint in the last few versions, and this one even loses a few. Many of of these features are also available in Power BI and Power BI report server, and Microsoft has taken the decision to deprecate this product. This gives customers with a PerformancePoint investment time to migrate their assets but is a clear indication that it will also be removed in a subsequent release.
PerformancePoint – Decomposition Trees
The Decomposition Tree feature in PerformancePoint came originally from ProClarity – one of the three products that made up the original PerformancePoint product. These visuals are based on Silverlight, and have been removed from the product accordingly.
PowerPivot for SharePoint
PowerPivot for SharePoint is not supported in SharePoint 2019. PP4SP was originally a combination of two technologies – a specialized version of SQL Server Analysis Services, and a SharePoint service application. In the 2016 version, these two parts were split into two – the SSAS component became a part of the SQL Server installation media as SSQL – PowerPivot mode, and the service application, which continued the name PowerPivot for SharePoint. To be clear, it is the second of the two that has been removed. SSAS PowerPivot mode continues to be an important component and is used by Office Online Server for working with Excel files that have embedded models.
Scheduled workbook data refresh
This feature allowed for the automatic refresh of the data stored within Excel workbooks in SharePoint. It requires a PowerPivot data model to work, but the refresh operation would refresh all connected data in the workbook on a scheduled basis. This was a component of PowerPivot for SharePoint. It has recently been announced that this capability will soon be available in Power BI Report Server.
Workbook as a data source
With PowerPivot for SharePoint deployed, it is possible to use the data model in a published Excel workbook as the data source for another workbook. This feature will no longer be available, and there are no plans at present to reintroduce it.
PowerPivot Management Dashboard
Originally a part of SharePoint Central Administration, the management dashboard provided status updates on all PowerPivot for SharePoint operations. Being a part of PowerPivot for SharePoint, this has been removed accordingly.
The PowerPivot Gallery is a modified SharePoint Document library form that displays worksheet thumbnails contained in published Excel workbooks. This component is Silverlight based, and part of PowerPivot for SharePoint. It has been removed accordingly.
Power View, Decomposition trees, and the PowerPivot gallery were the last remaining features that carried a Silverlight dependency. SharePoint 2019 no longer has any Silverlight dependencies.
These changes are significant for anyone with an existing Business Intelligence investment that plans to move to SharePoint 2019. I intent to write more about migration strategies and will be addressing these topics at various conferences in the future.
