View Native Query Now Works For Analysis Services Data Sources

If you’re familiar with the topic of query folding in Power Query, you’ll know that the View Native Query right-click option in the Applied Steps pane of the Power Query Editor can be used to show the native query that is run against the data source. You may also know that there are some data sources where query folding does take place but where View Native Query remains greyed out.

Exporting Data From Websites For Use In Power BI Using Power Automate UI Flows

As a Power BI developer I know how Power Query makes it easy to get data from web sources, but I also know there are limits to what it can do. I can get data from tables on web pages, I can get data from web services, but when confronted with a website where you have to click a button to download a file there’s a problem.

Power BI Report Performance And The Number Of Visuals On A Page

When you’re faced with a slow Power BI report it’s very easy to assume that the problem is something to do with the dataset, how it’s modelled and how the DAX has been written, and then disappear down a rabbit hole of Marco-and-Alberto videos trying to shave milliseconds of the time taken by each DAX query the report runs.

Displaying Routes On A Map In Power BI

In last week’s post I described the new Power Query M functions for working with Well Known Text objects, and in a post a few weeks ago I showed how you can use the Icon Map custom visual to display Well Known Text data.

Create a relationship with multiple columns in Power BI

When building Power BI reports we often need to join two (or more) tables together, but what if the relationship is defined by two or more columns? Relationships in Power BI are limited to single columns, but whilst this seems like a major limitation there is actually a simple solution to create a relationship with multiple columns in Power BI.

To create a relationship with multiple columns in Power BI we simply need to create a new column by merging the required columns together. What’s more, if we use the same name in both queries Power BI will automatically create the relationship for us.

Dynamically Generated Lines On A Map In Power BI Using DAX, WKT And The Icon Map Custom Visual

I don’t generally blog about data visualisation in Power BI because it’s not my strong point, and I don’t blog about maps and geospatial analysis because I know even less about that subject and there are people like David Eldersveld who cover it so well. I do like playing around with maps though and recently I’ve been having fun with the Icon Map custom visual developed by James Dales.
