Today I’m going to share my solution to a question I found on the MrExcel forum. It’s an interesting problem. https://www.mrexcel.com/board/threads/power-query-to-determine-consecutive-and-non-consecutive-dates.1261496/ Let me briefly explain the problem. The Problem We have the following table, which contains the source data. Each row contains a unique ID (maybe a piece of equipment) […]
Last week I again had the pleasure of being invited by Rob Collie to be on his podcast Raw Data by P3 Adaptive. For those that are not familiar with my story, I identified Rob as a leader in the Power Pivot/Power BI space very early on (back in the […]
As you may know, Microsoft has an MVP Programme where it acknowledges and rewards community leaders for their subject matter expertise and contribution to the community. There are many benefits of being an MVP including the recognition (leading to people understanding that you must be doing something right if Microsoft […]
Have you ever had a situation where you have a slicer selection that “sticks”? You make a selection in a slicer, then make some changes somewhere else, but the first selection you made “sticks” when it is no longer valid? Take a look at this animated demo below to see […]
In this article I’m going to talk about the recent change that Microsoft has made in renaming the underlying database used in Power BI from the term “dataset” to “semantic model” (or as I would call it, “semantic data model”). The Word “Semantic” Let me start by talking about the […]
On 12th April 2023, Iman and I hosted Miguel Myers as our special guest at the Sydney Power BI User Group. Miguel is a visualisation guru from Microsoft and has worked there for many years. He has recently been assigned as the Product Manager for Visualisations in Power BI, and […]
Back in April 2022, I wrote an article called Poor Man’s Paginated Reports. That article covered an easy way to create a paginated report without having to learn how to use paginated report builder. Sometime since then, Microsoft has released the ability to create a simple paginate report online inside […]
I do a lot of Power BI model and report development; maybe you do too. There’s nothing worse than spending an hour or so developing your model only to have something go wrong and you lose your work. Things that can go wrong include: Your PC/App crashes. Power BI does […]
Microsoft has just announced the general availability (GA) of the integration of Power BI with PowerPoint. I have previously blogged about this feature here => Power BI Live Embedding. With the recent GA announcement comes a significant improvement over the public preview version. Power BI Single Visual Embedding in PowerPoint […]
The Power BI Matrix visual is similar to an Excel Pivot table, however there are quite a few limitations in the Matrix. In the Power BI Matrix below I have put the product categories on Rows, Calendar Year on Columns and the measure [Total Sales] on Values. At this point, […]
One thing I tell people over and over again, is that if you want to learn to be good using Power BI, you have to practice. One of the best ways to practice is to find a topic you are interested in and build something useful. River Murray Floods 2022 […]
I have been blogging about DAX since before Power BI was a product; I started back in 2014 and Power BI was first released as generally available in mid 2015. Until about 2017, the only way you could build a commercially viable production reporting tool that used DAX was via […]
Way back in 2019, I was fortunate enough to meet Jeffrey Wang while at the MVP summit in Seattle. Jeffrey is one of the fathers of the DAX language and as such he is a hero of mine. I sat through some presentations and discussions, and Jeffrey mentioned an idea […]
I love the Power BI community. There are so many great things that the community does. They help each other (think the Power BI community forum) and they also build fabulous third party external tools to enhance Power BI. Measure Killer This week I am sharing a brand new third […]
This is the third in my series where I show how I build a report from scratch. The objective is to show the warts and all process that I go through. Along the journey, I am sharing some tips and tricks. In this video, I demonstrate Standardising the data across […]
This is a follow up to my previous article and video where I demonstrated how to download data from multiple web pages into a data model. In this second article in the series, I demonstrate what I would normally do at the next stage of building a report. I often […]
Every now and then when I have a Power BI project of interest to me, I like to create a video of the end to end process of building a new report. This allows me to share some “warts and all” real-world examples of how to go about building a […]
Back in 2019 I ran a free webinar introducing Power BI and DAX. Many readers of my blog will already be well ahead of this topic, but then again many of you also probably run into people who would benefit from a simple introduction to DAX. I have decided to […]
I first blogged about this back in October 2021 when Microsoft announced live Power BI embedding was coming to PowerPoint. Believe it or not, the ability to embed Power Pivot reports into PowerPoint was one of the first features delivered by Microsoft way back in 2014 or 2015. It used […]
I’ve been pretty busy over the last few months. The demand for Power BI skills has never been stronger, and my company is super busy. I haven’t written a blog article for a while, but I wanted to take a bit of time out this morning to talk about the […]
