Power BI supports this performance, however it isn’t automatic, so if you release a summary visual without establishing drill through visuals, you may wind up with annoyed end users. The bright side is that while this functionality isn’t automated, it
is easy to establish. SEE: Hiring set: Microsoft Power BI designer (TechRepublic Premium)
In this tutorial, I’ll discuss how to include drilling performance to a summary visual in Microsoft Power BI. We’ll likewise talk about training end users on how to utilize the drill through function because it doesn’t deal with a double-click, as some might expect. Throughout this tutorial, I’ll be using Power BI Desktop on a Windows 10 64-bit system.
Here, you can download the Microsoft Power BI demonstration file for this tutorial and follow along.
Why you must consider drilling in Power BI
Drilling through associated data is a recognized function end users will likely anticipate. Drilling is a fantastic method to take a look at details; the function can be used to explore specific truths, gaining insight the original visual doesn’t provide. For example, if an end user is viewing a monthly sales report, they may utilize drilling to see all orders for that month.

Consider drilling as a way of searching for ideas about particular information that is displayed in a visual or report. It’s a bit like holding a lens to the main visual to read the small print. End users will most often use this function when they want to see particular information rather than the aggregate.
Now, let’s take a look at a simple dataset to see how end users can take advantage of drilling in Power BI.
How to prepare the summarizing visual for drilling
Let’s suppose you’re basing visuals on the sample dataset shown in Figure A.
This simple Power BI visual doesn’t link to any details. Specifically, you want to show a regular monthly sales report( Figure B). In this circumstance, end users may want to see the actual sales for a specific month, however when they double-click on a month entry, they get no extra information. They may then take a look around but discover absolutely nothing that reveals them the sales information they want for each month.
This donut visual in Power BI has no drilling performance, in the meantime. To establish drilling, you require a summary visual and any number of visuals that show the realities or information evaluated in those summaries. We’ll use a donut visual to display a regular monthly summary of sales based upon the dataset revealed previously in Figure A. In the next area, we’ll develop the drill through visuals.
To start, you should base a donut visual on the Quantity and Date fields in the TableSales table. Using the Visualizations pane, drag Date to the Legend bucket. Power BI will include a Month field, which it will use to sum up the information. You can specify a different date component by broadening Date Hierarchy.
Next, drag the Amount field to the Worths container. Power BI relabels it to Amount of Quantity since Quantity is a math column; Power BI assumes you will run computations on this field. You can rename the field in the visual if you would like to.
Where does the Data Hierarchy originate from in Power BI?
If you’re questioning where the Date Hierarchy came from, Power BI develops it when you import Time and Date worths by immediately including each date’s month, day of the week, year and so on. This is among the important things Power BI does internally, conserving you a great deal of work. Power BI uses the Vehicle date table, which you can’t see, however it’s utilized to produce Date Hierarchy.
To learn more about hierarchies in Power BI, you can read How to build a hierarchy to support drill mode in Microsoft Power BI. To get more information about date tables, you can check out How to understand if the Car date table is appropriate when utilizing Power BI and How to develop a date table in Microsoft Power BI.
Now, let’s include a drill through visual Power BI can display when an end user wishes to see all of the sales records for the month we have actually selected in the donut visual.
How to include a drill through visual in Power BI
End users may want to see the information assessed every month’s summary values shown in the donut visual. Right now, there’s no drilling in the visual. We’ll need to include drill through visuals– the visuals that will display information about monthly sales.
Must-read huge information coverage
To begin, include a new page; drill through deal with pages just. You can alter the page name if you like, but it isn’t needed. Then, add the visual you want to display the detailed records for each month.
Remember, the summary visual– the donut visual– shows month-to-month overalls. We want a visual that shows all of the sales records for the presently selected month in the donut visual. For example, if you select May, you want to see the sales records for May.
On page 2, include a table visual based upon all three fields. We do not need Area because there’s no drilling on Area, however end users might wish to see it.
Now, let’s include Amount as the drill through field. Right-click the Amount field in the Fields pane, and pick Contribute to Drill Through from the resulting dropdown (Figure C).
Include Quantity as the drill through field in the Power BI summary visual. If you inspect the Visualizations pane, you’ll see that Power BI
Quantity field to the Drill Through bucket, as displayed in Figure D. Figure D Power BI includes the Quantity field as the drill through field. How to utilize drill through in Power BI Everything is in location now, and the drill through performance is all set to use. To use it, go back to the donut visual on page one and right-click May. Then, select Drill Through and Sales Details, which is on page two if you didn’t relabel the page when you added it( Figure E). In reaction, Power BI shows the table visual filtered to show only the records for May, the selected month in the donut visual. Figure E Carry Out the Power BI drill through feature by right-clicking a month.
Figure F shows the drill through table, filtered to display just 2 records since there are just 2 sales records for May. Power BI filters the records by the month selected in the donut visual.
Power BI understands to filter the drill through table visual. To go back to the donut visual, hold down the Ctrl key and click the back arrow in the top-right corner. Despite the variety of pages in between the donut and the table visual, this arrow will constantly take you back to the donut visual. It belongs to the drill through function that Power BI included when you included the drill through field.
There are a couple of extra things you’ll want to know about this procedure:
- If you click the page two tab, the visual will not update. You must utilize the right-click drill through path.
- As is, you can drill one month at a time.
- Drill through fields should be in the original summed up visual– the donut visual, in our case. This restriction makes sense but does require a bit of preparation, so the drill through visuals can reveal the information your end users want to see.
- You can always include more drill through visuals. Simply bear in mind that each needs its own page.
If you’re dealing with end users who aren’t knowledgeable about Power BI, you must make the effort to reveal them how to utilize the drill through functionality. Otherwise, they might miss out on the function completely.

You may be questioning why you ‘d force end users to right-click and pick a drill through visual when you can utilize a filter on the exact same page. The majority of reports have a lot of visuals, however drill through allows you to group a number of high-end visuals on the primary page while still enabling end consumers to see information. It’s another way to set up data that can make information visualization simpler, depending on the dataset and usage cases you’re working with.
