Power BI Shared Datasets: What is it? How does it work? and Why should you care?

I have written a long time ago about sharing a Power BI dataset between reports, in an article written when the feature announced first. Nowadays, if you are in the world of Power BI, you heard a lot about certified datasets, and also shared datasets becoming available across multiple workspaces. In this article, you will learn about:

  • What is shared dataset in Power BI?
  • How the shared dataset can help in Power BI development?
  • Where is the place of Shared dataset in the Power BI architecture?
  • How shared dataset works behind the scene in the Power BI service?
  • What are Certified and Promoted Datasets?

To learn more about Power BI, read Power BI book from Rookie to Rock Star.

What is the Dataset in Power BI?

When you create a Power BI report (or let’s call it a *.PBIX file), the report has two components (if the data connection mode is import data); A report, and a dataset. When you are in the environment of Power BI Desktop, you can’t see the separation that easy, unless you go to the task manager and see the dataset running behind the scene under the Power BI Desktop task threads.

However, when you publish the PBIX file into the service (the Power BI website), you can easily see that there are two objects; A report, and a Dataset.

  • The report is the visualization layer of your Power BI implementation
  • The dataset includes the data, tables, relationships, calculations, and connection to the data source.

You can schedule the refresh for the dataset, and connect to on-premises sources (through a gateway), or cloud-based sources.

What is a Shared Dataset?

Now that you know about the dataset, let’s talk about the Shared Dataset. A shared dataset is a dataset shared between multiple reports. For a long time, you could create a new report from an existing dataset through Power BI website. This feature has been available from the early days of Power BI;

About April 2017, The ability to create a report from Power BI Desktop that can point at an existing dataset, and has a live connection to the existing dataset, became available, which I have written an article about it here.


Those days, it was called; Get Data from Power BI service. Nowadays, this feature is renamed as getting Data from Power BI Dataset;

A shared dataset is a dataset that shared between multiple reports. Multiple reports connecting to one shared dataset. When that dataset gets refreshed, all of those reports will have the new data. A shared dataset is one step closer to the multi-developer tenant in Power BI environment.


Sharing Datasets Across Multiple Workspaces

For a long time, sharing datasets was only possible inside a workspace. You could not use a dataset from workspace 1 as the source for a report in workspace 2. However, recently, the feature became available, and you can share the dataset even across multiple workspaces. This is an amazing update and changes the way that Power BI Development works in the future.

When you get data from a Power BI dataset through the Power BI Desktop, you have the option to select which dataset you want to get data from;

How does Shared Dataset work behind the scene?

When you share a dataset in the same workspace, everything is clear. You have one dataset to schedule refresh, and multiple reports connected to it. however, when you use a dataset shared from another workspace, you get something which might look a bit different.

Linked Dataset

When you get data from a Power BI dataset which is workspace 1, and then save your report in workspace 2, you get something like a copy of your dataset in the workspace 2. This might look strange! You might say, this is not a shared dataset, it is a copied dataset. The fact is that what you see is just a link. Power BI will bring a link to that dataset into the new workspace, this link helps you to understand when the dataset gets refreshed last time.

Here is what a linked dataset looks like and you can see the difference of that with normal datasets.

You cannot manually refresh or refresh based on the schedule on a linked dataset. The refresh action can be only configured in the main dataset. The linked dataset is just a link, showing you when was the last date and time for the refresh, and an easier way to generate more reports from that dataset.

A linked dataset is not a copy, It is a link to the original dataset.

Certified and Promoted Datasets

When Power BI developers use the function of Getting data from Power BI dataset, They see all datasets from all workspaces that they have access to. This might be a bit confusing. There might be tons of datasets shared in the environment. Developer ends up with questions such as: Which of these is the one I can use? Which of these are valid to use? which of these are reconciled and tested? which of these are reliable to use? and etc.

A new labeling system is added to the Power BI datasets, that helps in this scenario. You can mark some of the datasets as certified, and promoted. To get a dataset certified, there is an approval process that can assure the dataset passed some of the tests. You can clarify through this labeling system, that what are datasets good to be used as the source, and what is not. You can build the concept of Gold, Silver, and Bronze datasets. Having gold datasets as datasets that are fully tested, and reconciled, and then down to other levels, where the Bronze dataset is a dataset that hasn’t been through any testing yet.

To use this labeling system, the creator of the dataset can go to the setting of the dataset;

In the settings, you can set the Endorsement level as below;

As you can see the Certified option might not be available. The Power BI tenant administrator has the authority to enable that labeling, and give access to whom needed in the Tenant Settings;

The labeling system helps Power BI developers to then see what is the level of certification that a dataset has to be used as a shared dataset, and then can select based on that respectively;

Shared Dataset in the Power BI Architecture

I have written a lot of articles about the architecture of Power BI, in fact, gathered them in a book, However, in one article specifically, I explained how Dataflow and Shared datasets can play an important role in the multi-developer tenant of Power BI implementation.

In nutshell, using the Dataflow makes sure that you can bring the data well prepared in a central area, which you can call it a centralized data warehouse in the Azure Data Lake. and using the shared datasets, you can build data marts that can be used by multiple reports. Here is how the architecture works in the diagram view;

Instead of having silos of Power BI reports and files everywhere, You can build an architecture that works best with multiple developers, less redundancy in the data, in the code, and the logic, and easier maintenance approach. I highly recommend reading this article to learn more about this architecture, and learning how the shared dataset located in this architecture as a key element.


The shared dataset is not a new feature in the Power BI, However, the ability to share it between multiple workspaces announced recently and is a game changer in the architecture of Power BI implementation. Using shared dataset, you can have centralized data models (data marts) that can serve multiple reports. You can reduce the maintenance time, the redundancy of the code, and the data through this approach. Having the labeling system of the certified or promoted dataset is also a great way of putting some process and governance in place to make sure the shared datasets has been through some process of testing and reconciling.

Are you using shared datasets in your implementation? if yes, I like to hear about your experience, if not, I like to know why you don’t find it useful for your implementation. Either way, please share your thoughts down in the comments below.

    • Hi Amit.
      Let’s hope for it. At the moment, the only way to do that is through SSAS. but hopefully shared dataset becomes available in PBIRS too

  • Great article. 2 questions.

    1. Dataflows allow incremental refresh – but I appears when utilizing them in a .pbix and deploying to the service that it loads all data from the dataflow. Thus, efficiency from the dataflow incremental refresh is lost by the dataset having to load all the data again.

    2. While I can build new reports on shared datasets, I cannot fortify the dataset with any other new information I want for those reports. Meaning, I can’t mashup data with anything new outside that existing model

    Am I doing something wrong in either case?

    • Hi,
      At the moment, the connection from Dataflow to Power BI only supports Import Data. Later in the future, you would be able to do DirectQuery hopefully as well.
      on the other hand side, when using Incremental Refresh, you can set that up also in the Power BI dataset, in addition to the Power BI dataflows. Incremental refresh in the dataflow makes sure the ETL runs on delta load, setting that up in the dataset, makes sure then model also runs under partitioning.
      Regarding mashing up data of the shared dataset. I would say it is a good thing that you cannot do more data mashup with a live connection to the Power BI dataset, because then your source code will spread all over places, and you cannot easily find where you have done what! If you need to use the Power BI dataset as one of the sources, and do data mashup on that and combine it with other sources, then don’t use Get Data from Power BI dataset, You can use Power BI dataset as an Import data source (it is now possible with XMLA endpoint), and then you can do whatever you want with PQ there.

  • To follow up on Utwku’s point 2 above:

    I have a shared dataset the pulls a number of tables from salesforce and does various cleaning/transformations of those tables, links them correctly, and has a bunch of measures.

    I do have one situation in which a report needs to pull from that shared dataset AND from a few .csv files.

    What is the best way to go about doing that, given this limitation?

    I only need those few .csv files in the one report, so it seems silly to go back and add those to the shared dataset.

    • Are you using dataflows too?
      if yes, then the tables that you have in your shared dataset, should be already populated through dataflows. so you can build another dataset, using those tables, and your extra .csv files.
      Of course, this method, still won’t give you the measures in the other dataset.

  • We are using a shared dataset however the issue is that when my Report which is workspace 2 and pointing to Workspace 1, my users are getting issue which says “You cannot see the content of this report because you do not have permissions to the underlying dataset. Please contact the dataset owner to request access”. Once I explicitly provide read access to those users on dataset in Workspace 1, then they are able to see the report. Is this true?

  • Hi,
    we are using a shared dataset, but the issue we have is around source control.

    I can source control the original Dataset and the Report, but the shared Report cannot be exported as Pbit or Pbix. While the Dataset is a live connection to the original, the Report is a new independent Report, with no connection to the original. How do I source control the new one?

    Any ideas greatly appreciated

    • Hi Ed
      Where do you create the new reports? if you create the reports in Power BI Desktop using Get Data from the Power BI dataset, then you can save them as PBIX.
      and you can use the source control system you want for it.

      • Hi Reza,
        If for example I go, Get Data > PBI Dataset > “Commercial” ….. a dataset I have built that is published to the “Commercial” workspace, and I build a report, I can ONLY publish to the same workspace, “Commercial”.

        If I then use the “Save a copy” functionality in app.powerbi.com, I can select a new Workspace for my report, “Marketing” for instance, but then this new instance of the report is orphaned. I can edit in the service as I please, but cannot export as pbix.

        This means V1 of the report in “Commercial” is on my desktop, safe, but V” in “Marketing” could diverge without any version control.

        • Hi Ed
          You CAN publish your new report that is generated using Get Data > PBI Dataset > “Commercial” into another workspace. This would generate a new dataset in the second workspace, which is a link to your “Commercial” workspace. This new dataset is not a “real” dataset, it is just a link. If you want to make any changes in the dataset, the original one in the “Commercial” workspace needs to be changed.
          Save a copy, creates a “real” dataset as a copy, and then you get into the problem of having multiple copies and the version control issue.

          • Hi Ed
            I see. I think I get where the problem is, finally!
            When you use save a copy, and save it to another workspace, then you cannot download the PBIX from the second workspace.
            I usually don’t notice these things, because I don’t use the save a copy feature
            I start with a Power BI Desktop file, Get Data -> PBI Dataset , build the report, then publish it to the second workspace. If you use this approach, you CAN download the PBIX copy from the second workspace.

  • Hi Reza,

    Does Shared data set concept work for Power BI report server too.
    I want to import a dataset from PowerBI desktop for report server and create report using that.Is this feature available for free users too because we have not took any separate license for publishing the reports,I am uploading the data sets directly to report server.


    • Hi Anvesh
      You can use a shared dataset from the Power BI service, in a report that is hosted in Report Server. so it supports the shared dataset.
      However, I guess your question what that; can you have a Power BI dataset hosted not in the service, but in the Report Server only, and use it as a shared dataset for other reports in that report server. If that was your question, the answer to that is no, not yet, but hopefully, that will come in the Report Server too.

  • Hi Reza, do you know why is not allowed to share a dataset using O365 groups? Makes no sense we can grant access using them but not to a dataset. Any idea?

    • Depend on the method you use, you can!
      If your shared dataset is hosted in an organizational workspace, then you can share it with an O365 group by simply adding that group as a Contributor to that workspace.

  • Hi Reza

    I want to have 2 roles in out reporting team: administrators and report builders:
    – Administrators create dataflows and datasets that can be used inside the organization
    – Report builders can use these dataflows and datasets to build reports.

    I don’t see the possiblity to limit the access for report builders. I want to give them enough access to use the created dataflows and datasets when building reports, but without edit rights. Is this possible?

    If my first question is possible, is there a way to see the content of a dataflow/set? Now you need edit rights before you can see the content of dataflows/sets. I was thinking of a tool or a plugin to view the content, but I can’t find a solution for this.

    Thanks for your feedback.


    • Hi Bjorn
      Unfortunately, the only option for Report builders is to have Edit access on the dataset.
      This can be achieved with Contributor role in the workspace.
      However, if you are worried that they might change the content in this workspace, you can create another workspace, create a linked dataset in there, and get Report Builders to use the other one, however, even in that case, they need to have access to the original dataset.
      Another option is to use Power BI Apps, and enable the “user can work with underlying data option”
      The Power BI security roles are not yet persona based on the developer type. All developers considered the same, even though the report developers needs a different access from dataset developers. This might change in the future though, the whole concept of decoupling dataflows, datasets, and visualization is new, and I guess there will be security roles in the future to support that concept.
