After what seems like a lifetime of waiting for the paperback book economy to tick its required boxes, both of my new books Supercharge Excel and Supercharge Power BI are now available to ship to most countries in the world from Amazon.com. This is a good opportunity for me to […]
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. 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 […]
Level: Advanced I was answering an interesting forum question last week, and as is often the case I thought it would make an interesting article to share with you all here. I have modified the scenario a bit for this article and have built out some test measures to help […]
Today I want to issue a warning to anyone considering using Publish to Web to share corporate data internally within an organisation. Publish to Web is a standard feature on all Power BI accounts (free and Pro) – I first wrote about it two years ago here. This is a […]
There are lots of different ways that you use to do Text Filtering in Power BI including: Slicers (with various configurations) Cross filtering from any visual object The filters pane on the right hand side of your report Custom visuals designed specifically for filtering Most of these standard filters require […]
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: Advanced The EARLIER() and EARLIEST() functions are 2 of the harder functions in DAX to get your head around. If you come from a programming background it will probably be easy for you. However as I have repeatedly stated on my blog, one of the many great things about […]
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 […]
Regular readers of my blog probably get sick of hearing me rave about the latest new thing in Power BI. This month there is an absolute cracker – Q&A in Power BI Desktop. In case you don’t know, Q&A is a natural language query tool that allows you to ask […]
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 […]
Where has Matt been? Before teaching you how to pass an Excel parameter to Power Query, I’ll have a few words. Regular readers of my blog may have noticed I have been missing in action over the last month. I have been super busy with the PUG World Tour, delivering […]
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 […]
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: Advanced I was helping someone on Power Pivot Forum last week with a tricky calculated column question. As an aside, you may know that I always advise beginners to keep away from calculated columns. You mostly don’t need calculated columns because in most circumstances a measure is a better […]
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 […]
I have written articles before about how you can extract measures from a data model using DAX Studio and also using Power Pivot Utilities. These are both excellent tools in their own right and I encourage you to read up on those previous articles to learn more about these tools. […]
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 […]
