One of the features of Power BI (and Power Pivot) is that data cannot be changed once it is loaded into the database – this is by design. Power BI is a reporting database, it is not a spreadsheet. Power Pivot and Power BI are built to faithfully report on […]
This article is a follow on from last week. I recommend you go back and read the article first if you missed it, but in summary, I want to write a measure (not a calculated column) that will return the median sales of products while excluding the products with blanks (no […]
I was going to title this blog “MEDIANX and the X Functions”, but that sounded too much like a 2030s band, so I opted for MEDIANX returns blank in DAX. But the article does indeed cover more than just MEDIANX and the blank “problem”. But first some background. I helped […]
I’m sure many of you will already know that today is Power BI’s 5th birthday. It has been another great year of development by the Power BI team at Microsoft and the product has literally become so compelling that virtually every organisation should be considering deploying this tool. I cite […]
The July 2020 version of Power BI Desktop released a new feature called the External Tools toolbar. This was announced back in May during the Microsoft Business Applications Summit, and I have been waiting eagerly for it to be released ever since. In this short article today I am going […]
I was doing some work for a customer this week – they had a performance issue with a Power BI report. The data in the workbook wasn’t overly large, about 400,000 rows, yet the file size was 110 megabytes and the performance of the model was relatively slow given the […]
I have learnt a lot over my 50 something years in life, and one of my greatest learnings is that “it doesn’t matter how much you already know, there is still more to learn”. Hopefully this is one of the reasons you read my blog – because you want to […]
I was helping a client this past week to calculate the total business hours between a start date/time and an end date/time, taking into account the working days, public holidays and non-working weekends, etc. As is often the case, I thought it would be a great blog article that I […]
Power BI is and incredible product, yet there are still niggling issues that can frustrate and annoy the best of us (me included). Having said that, changes and improvements are happening all the time and it is easy for new features that address old issues to slip past us without […]
I see lots of chatter on Twitter and other media about the use of “small multiples” as a great way to communicate information across different subsets of data – yes Jeff Weir(d), that means you. I thought I would write a quick article about the concept to draw your awareness […]
This is a further (fourth) update/edit to this article I first wrote in Apr-17. I then updated it again in Jan-18, Jun-18 and again now in May-20 (Jason did a full review this time around). When I update my articles, I change the original post with the latest and best […]
There was a very subtle but important change made in the April 2020 release of Power BI Desktop that you may have missed. Take a look in the format pane on the right in the image below – do you see it? Note the “new” function buttons? When I say […]
Have you ever had report consumers that just don’t read your instructions? Well, you’re not alone. Having delivered our Module 1 : Data to Dashboard training for about 4 months now, I have often been challenged during the Drill Through Reports topic, with students commenting “I’ve tried text based tooltips […]
A few weeks ago, Danielle Stein Fairhurst from Plum Solutions contacted me and asked if I would speak at her financial modelling meetup group (a topic of my choice related to Power BI). I decided to speak about creating a P&L using Power BI and DAX. I first learnt how […]
OK, by now you will likely be getting to understand that I think Tabular Editor is pretty cool. I like every bit about it, and I am learning more every day. Daniel Otykier has done a great job with this wonderful bit of software, and the more I use it […]
In my article today I am going to share another COVID-19 Power BI report with you to explore, and at the same time take the opportunity to talk about Microsoft AppSource and how it can be used to distribute Power BI Apps. Before we move on, just a bit of […]
Have you been sitting back thinking about building your own Power BI Coronavirus report, but haven’t known where to start? Many people tell me they want to get more practice using Power BI but don’t have any suitable data to do so. You can now easily build your own Covid-19 […]
This is my third article about Tabular Editor, the others being the recent introduction article a few weeks ago, an also an article explaining how to copy measures between PBIX files. I watched the excellent webinar series organised by my friend Mike over at PowerBI.tips where Daniel gave a more […]

Well Covid-19 is a right royal pain in the backside for everyone. Am I right, or am I right? Everyone is effected to some extent, of course some more than others. One implication for me is that no one is able to attend my fantastic live, face to face Power BI […]
