Create a report from the OData feed with Power BI
This article explains how to create a treemap visualization using Power BI Desktop with an interactive filter. For example, your CFO might like to how the overall distribution of devices compares to just company owned to personal devices. The treemap provides insight into the total number of device types. You can review the number of iOS, Android, and Windows devices that are either company owned or personally owned.
Overview of creating the chart
To create this chart, you must:
- Install Power BI Desktop if you don't already have it.
- Connect to the Intune Data Warehouse data model and retrieve current data for the model.
- Create or manage the data model relationships.
- Create the chart with data from the devices table.
- Create an interactive filter.
- View the finished chart.
A note about tables and entities
You work with tables in Power BI. A table contains data fields. Each data field has a data type. The field can only contain data of the data type. Data types are numbers, text, dates, and so on. The tables in Power BI fill with recent historical data from your tenant when you load the model. Although the specific data changes with time, the table structure won't change unless the underlying data model is updated.
You may be confused by the use of the term entity and table. The data model is accessible through an OData feed. In the universe of the OData, the containers that are called tables in Power BI are called entities. These terms both refer to the same thing that holds your data.
Install Power BI Desktop
Install the latest version of Power BI Desktop. You can download Power BI Desktop from: PowerBI.microsoft.com
Connect to the OData feed for the Intune Data Warehouse for your tenant
You need permission to Reports in Intune. For more information, see Authorization.
Sign into the Azure portal.
Choose All services > Intune. Intune is located in the Monitoring + Management section.
Open the Intune Data Warehouse pane.
Copy the custom feed URL. For example:
Open Power BI Desktop.
Choose Get Data > Odata feed.
Paste the custom feed URL into the URL box in the OData feed window.
Select Organization account, and then sign in with your Intune credentials.
Select Connect. The Navigator will open and show you the list of tables in the Intune Data Warehouse.
Select the devices and the ownerTypes tables. Select Load. Power BI loads data to the model.
Create a relationship
You can import multiple tables to analyze not just the data in a single table but related data across tables. PowerBI has a feature called autodetect that attempts to find and create relationships for you. The tables in the Data Warehouse have been built to work with PowerBI's autodetect feature. However, even if PowerBI doesn't automatically find the relationships you still manage the relationships.
- Select Manage Relationships.
- Select Autodetect... if PowerBI has not already detected the relationships.
The relationship is displayed in a From column to a To column. In this example, the data field ownerTypeKey in the devices table links to the data field ownerTypeKey in the ownerTypes table. You use the relationship to look up plain name of the device type code in the devices table.
Create a treemap visualization
A treemap chart shows hierarchical data as boxes with in boxes. Each branch of the hierarchy is a box contains smaller boxes showing subbranches. You can use Power BI desktop to create a treemap of your Intune data.
- Select a chart type. Select Treemap.
- In the data model, find the devices table.
- Expand the devices table and select the manufacturer data field in the Fields panel.
- Drag the manufacturer data field to the Treemap chart on the report canvas.
- Drag the deviceKey data field from the devices table to the Values section under the Visualizations pane and drop on the box labeled Drag data field here.
You now have a visual that shows the distribution of manufacturers of devices within your organization.
Add a filter
You can add a filter to your treemap so that you can answer additional questions using your app.
To add a filter, select the report canvas, and then select the Slicer icon () under Visualizations.
Find the ownerTypes table and drag the ownerTypeName data field under the Filters section in the Visualizations panel.
Under the devices table, there's a data field called OwnerTypeKey that contains a code as to whether a device is company-owned or personal. Since you would like to show friendly names in this filter, look for the ownerTypes table and drag the ownerTypeName. This example shows how the data model supports relationships between tables.
You now have an interactive filter that can be used to toggle between company owned and personally owned devices. Use this filter to see how the distribution changes.
- Select Company to see that the company owned device distribution.
- Select Personal to see the personally owned devices.
