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. […]
The 24th of July, 2017 is the second birthday for Power BI. I thought I would take the occasion of its second birthday to reflect on all the great work that the crack Power BI team at Microsoft has done over the last year. I think it would be […]
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).

I was reading a blog by David Eldersveld last week where he was talking about his entry in the Microsoft Data Insights Summit Data Analytics Challenge. I originally was too busy to enter however I was inspired by his article and thought I should prepare an entry albeit with only […]
At the start of May 2017, Microsoft announced that Export to Excel/CSV would no longer be available to Power B Free users, and would not be part of the new Power BI Premium offering either. Today Microsoft announced that it has listened to community feedback and has agreed to include this […]
I am an enthusiastic sponsor of Microsoft BI. I have been fortunate enough to build a new career off the back of the great products Microsoft has developed, specifically Power BI, Power Pivot and Power Query. Having said that, I am definitely disappointed with the new licensing agreement changes have […]
Microsoft today announced that it is changing the way it licences its Power BI service product. I want to provide my personal view on why it is doing this, what is good and also what is bad about this change. The Problem MS is Trying to Address Let me start […]
A client contacted me recently and asked me to solve a problem for them. They have a large Power Pivot Excel workbook with lots of Pivot Tables. All was good except sometimes when they refreshed the data, the newly loaded data changed the shape of some of the pivot tables […]
