I first learnt about the new DAX UNICHAR function in Power BI by reading Chris Webb’s blog (which was also the inspiration for this article today). One of the uses of the UNICHAR function is to be able to include non text characters inside visuals. When you combine a logical set of […]
Level: Intermediate The variable feature in DAX has been around for more than a year and I have simply never got around to writing an article about it – I am changing that today. Let me start off with some version information and syntax and then I will show you are […]
Level: Beginners/Intermediate In the August 2017 update of Power BI Desktop Microsoft released the new What If feature (first demonstrated at MDIS in July). This new What If capability uses two new DAX functions to complete a task that you have always been able to do manually. You still can […]
Level: Intermediate In this article I am going to write about the ALL() function, show how it works and explain a common use case. I will also cover the unexpected behaviour that occurs when using the ALL() function in Power BI Desktop – more on that later. For this article I […]
Level: Intermediate Sometime late in 2016 Microsoft deployed a new “Combine” feature in both Power Query for Excel (Get and Transform) and also in Power BI Desktop (Get Data). The new capability makes it easier to combine multiple copies of similar workbooks into a single table without hand coding M Functions, […]
Level: Beginners/Intermediate As those that read my blog regularly would know, I have been at the Microsoft Data Insights Summit in Seattle Washington for the last 2 days. I had the privilege and pleasure of presenting two sessions at the event. For those that were not able to attend, here […]
Level: Intermediate This is the final article in my series about DAX as a Query Language. In my first article I introduced DAX as a Query Language and then in my second article I went in deeper to the specifics on how to use some of the more useful DAX query […]
Level: Intermediate In my last article I introduced DAX as a Query Language and explained why learning to query your data model can be useful. I covered the basics about using a tool like DAX Studio to query a database and return a table of data as a result. In this […]
Level: Intermediate I have written quite a few articles that contain embedded references to DAX Queries and DAX Table functions in the past. Today I am writing an article that introduces the DAX query language from the beginning so you can learn how to use it and how it will […]

Level: Intermediate I was helping a user on http://community.powerbi.com this week. The user had a list of service desk tickets for multiple customers and the requirement was to identify when a customer opened a second new ticket within 7 days of closing a previous ticket. This is not an uncommon scenario […]
Level: Intermediate Last week I shared how it was possible to easily create an online survey using Excel for O365. Once such a survey is created, the data can be imported into PowerBI.com and used to create a simple report. The biggest issue with directly connecting to OneDrive like I showed […]
Level: Intermediate [Edit: April 2019] Microsoft made the PDF Connector in Power BI generally available in April 2019.

Level: Intermediate There was an interesting question this week on http://powerpivotforum.com.au asking if there was a smarter way to user Power Query over multiple identical web pages to scrape the data in a single query. I have been meaning to blog about this for a while, so it is a […]
Level: Intermediate Update: 2019. You can now do this natively in a Matrix, but this is still a good trick that can be used to solve various problems. You may or may not be aware that it (previously was) not possible to put Measures on rows in a Matrix in […]

Level: Intermediate Last week at my Sydney training course, one of the students asked me a question about LASTNONBLANK. This reminded me what a trickily deceptive function LASTNONBLANK is. It sounds like an easy DAX formula to understand, right? It just finds the last non blank value in a column […]
Level: Intermediate I helped a member at http://powerpivotforum.com.au with a problem last week that ended with an interesting solution. The explanation of how it worked was a bit complicated and worthy of sharing, hence this is the topic of today’s post. Count the Working Days Between Two Dates The requirement […]
