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) […]
Level: Intermediate Why You May Want to use RLS Imagine you’ve just built a Power BI report filled with sensitive financial data. You want to start to share this data across the organisation but not everyone is allowed to see everything. The CFO should be allowed to see everything, but […]
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a selection in a slicer, then make some changes somewhere else, but the first selection you made “sticks” when it is no longer valid?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 […]
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, […]

I have many reasons for sharing content online. The main reasons are that I like sharing what I know, but also that I want to document how to complete a task for future reference. My article today ticks both of those boxes. How Many Employees by Period I’m calling this […]
What?! Exploding Measures I hear you say. Exploding, expanding, use which ever word you like; what I mean is when you want to remove any refence to a measure INSIDE another measure. Example Consider the 3 measures below. Total Sales = SUM(Sales[ExtendedAmount]) Total All Product Sales = CALCULATE([Total Sales],ALL(Products)) % […]
Paginated Reports have been available in Power BI since 2019. They serve an important purpose, but they are not easy for the average business user to learn, plus they require Power BI Premium to use. In my blog and video today, I will show you how you can use Excel […]

This is a follow up article from my last blog post where I demonstrated how easy it is to use two slicers to compare any two items. In the demo in my article, I specifically showed how you could compare any 2 years of choice, but the principle applies to […]
This is an update to an article that I wrote back in 2019. This time around I created a video to go along with the written explanation and documentation below. You can jump straight to the video below if you prefer that medium. What is Calendar Over Run? Consider the […]
