I was in Seattle, USA in the last week of July participating in the Microsoft Business Applications Summit (MBAS). I love attending conferences like this and it was a privilege to present on a few topics over 3 days. Evaluation contexts in Power BI DAX One of the presentations I gave […]
Level: Intermediate Matt: This is the second one in a series of articles from Parker Stevens. In this article he talks about using R with Power BI. If you missed his first article “Introduction to DirectQuery” you can read it here. Parker: Power BI comes with a ton of built-in […]
One thing I did a long time ago was set up my own forum called PowerPivot Forum. This forum is open to anyone to join and to ask questions and/or help others. If I have any spare time (decreasingly so these days), I help people out on the forum too. It occurred […]
Level: Intermediate A couple of weeks ago I posted a list of my ideas that I have created at ideas.powerbi.com and asked you to vote for them if you agree with the concept (please go back and take a look if you missed it). I thought it would be interesting […]
Level: Intermediate. I had a great question pass my way last week while I was at the Microsoft Business Application Summit. The problem presented by Matt (a different Matt, not me) was that he had around 200 measures already written, but wanted to be able to toggle the report pages […]
Level: Intermediate I do lots of live training, face to face and online, and I always encourage students to bring along any business problems they would like some help with. Last week I had a great problem that Debbie shared with me that I thought was worth creating this blog […]
Level: Intermediate I wrote an article earlier this year that showed how you can take a table of future growth rates (different growth rates each year) and then calculate the future value of an investment using DAX. I had a follow up question from Steve asking if it is possible […]
Matt Here: I first met Ivan via Twitter when he was living in Russia, and then in person when he moved to Australia to live in Sydney with his family. Ivan is a talented Power BI professional and I have learnt many things from him over the last few years. […]
Level: Intermediate I got my haircut today (pretty spiffy one too, even if I do say so myself). While I was chatting I asked my hair dresser “on average, how often should I get my hair cut”? She told me (for men) around 4-6 weeks. Then I got thinking (as […]
Level: Intermediate Last week I presented a webinar with Chuck Sterling (from Microsoft) on the topic of Time Intelligence. This was a YouTube broadcast event that anyone could join live, however it has also been recorded and can be watched at any time (see below). This article is a follow […]
Level: Intermediate to Advanced Matt here. I recently met Parker Stevens online through LinkedIn – he too is a Power BI fan, just like me. Parker has shared a few techniques with me that I found very interesting. These topics have not been covered on my blog before and hence […]
Level: Intermediate. Sometimes, just when you think you are getting the hang of the DAX language, something happens that completely baffles you. Such events can cause you to doubt your own learning and progress. But let me assure you – this happens to EVERYONE at sometime or another. In this […]
There are some things that are very easy to do in Excel that don’t seem to have an immediately obvious and simple solution in DAX. One such problem is when you want to apply compound growth on an investment. Let me make up an example so it is clear what […]
Power Query for Excel has developed at a striking pace over the last few years making it hard to keep up with the changes. Over several iterations, the Queries and Connections pane has been called various names, and the behaviour has changed a few times too. Depending on the version […]
I recently attended a school reunion (class of 1981 for what it’s worth – wow, I’m old!). We all had a great time catching up, looking at old photos, taking new photos etc – how things have changed! Anyways that got me thinking that it would be great to do […]
Level: Intermediate I was helping someone on a forum recently and I thought the question and solution would make an interesting blog article. I have adapted the scenario to work with Adventure Works customer purchases, but this concept would work equally well across other entities, such as sales territories, calendar […]
Level: Intermediate–Advanced I have covered the topic of Lineage in DAX a few times in the past (within other articles). Today I thought I would write a single post dedicated to lineage. As you may know, Power BI has a number of different operation modes, some of which do not […]
Level: Intermediate I have been aware of the TREATAS function for a very long time. I have tried to understand how it works a few times but could never really work it out. I think part of the problem is the function name TREATAS is not very descriptive. To contrast […]
I’m really pleased and excited to introduce you to Daniil Maslyuk (Twitter: @DMaslyuk). I first met Daniil about a year ago (originally via email) as he was preparing to move to Australia. Daniil made the plunge shortly there after and migrated to Australia (from Russia) – he now works as a Power BI consultant […]
Level: Intermediate Background I was reading the questions at http://community.powerbi.com today and saw an interesting question. In short the OP wanted to know if there was a way to identify (via a measure) if the row in a table had a colour =”Blue”, but also to check that there were […]
