The team at Power BI is setting a blistering pace of updates and improvements for PowerBI.com and Power BI Desktop. One of the great improvements in the November 2015 update is the ability to control how cross filtering between charts (and other objects) on the canvas works. The default cross […]
Level: Beginners I was helping a user at http://powerpivotforum.com.au with a question about collections reporting and thought it would make a good blog post. There are a few interesting concepts involved which I will explain as I go along. The scenario is as follows. We have 2 tables – one […]
Level: Beginners I have had some really good positive feedback from a couple of early readers of my new book “Learn to Write DAX”. “I purchased your eBook last Saturday and I want to let you know that I have learned more in the last 96 hours than I have […]
Level: Beginners No software company can build every single feature that everyone wants to see all at once. Ultimately there has to be some prioritisation, and along with the prioritisation comes compromises and ultimately disappointments for some (many?). Back in July 2015, Microsoft started a chain of actions and announcements […]
Before showing you how to do cross join in power query, let me tell you a story. I had a situation this week where I need to create a budget table in Power Pivot. I had a choice of either loading a weekly budget as a single record per store […]
Level: Beginners When you write a Power Query workbook in Excel 2013, you are given 4 choices of what to do with results. One of the choices is to load the resulting query directly to the Power Pivot data model. This choice does not exist in Excel 2010. It is […]
As regular readers of my blog would know, I attended the PASS Business Analyst Conference in Santa Clara California this year (April 2015). Here is the link for next year if you are interested. While I was there, I had the pleasure of presenting on one of my favourite topics […]
I was helping a participant at http://powerpivotforum.com.au with a problem. Long story short, she needed to return a table to Excel from a data model – not a Pivot Table. This concept can be a bit strange at first – let me explain. Tables – Not Pivot Tables A Pivot […]
Level: Beginners I helped a couple of people this week on the topic of creating multiple relationships between two tables. There is not a lot of information on this topic on the web so I thought I would write about it here. Power Pivot is not the Same a Relational […]
I am really looking forward with anticipation and excitement about the future of http://PowerBI.com. Microsoft has just released the August 2015 update to Power BI Desktop just 1 month after PowerBI.com becoming generally available (GA). Power BI Desktop used to be called Power BI Designer, and it is the tool […]
Level: Beginners I have blogged before about how to combine multiple files in a folder using Power Query. The way I have always done it is to use a Function, and this is not hard to do if you follow the instructions I provided on my last blog on this topic […]
Level: Beginners One of the topics in my book “Supercharge Power BI: Power BI is Better When you Learn to Write DAX” talks about the optimal shape of your data tables. It is such an important topic that I have decided to share some modified extracts from the book here. When […]
Level: Beginners I have been working with a client here in Sydney were we are producing some Human Resource (HR) reporting tools to analyse what is happening across the business. HR data is quite often very sensitive because it can contain personal information as well as salary information. A lot […]
Level: Beginners I was working with a client recently and was asked a question… “How do I remove duplicate connections in Power Pivot”? I know this is an issue and I specifically advise people to be careful in my training courses and also in my book. But of course once […]
I was working with a client last week and the unthinkable happened. The client made a simple editing mistake inside the Measure editing dialogue box and it corrupted the Power Pivot workbook. We could still edit the corrupt workbook, but the Pivot Tables stopped working. Oh No!! Now what? He […]
I use Excel 2013 64 bit and sometimes Excel just keeps crashing on me. It used to happen to me a lot more in the past, but after I discovered what was causing the repeat behaviour I have been able to greatly reduce how often this occurs. First a description […]
I love VBA for Excel. VBA can automate tasks that you use often, making the process faster, easier and more accurate to execute. I like writing VBA for myself to solve my own problems, I like sharing what I write with others, and I like taking the VBA that others […]
Excel is a bit like a drug for me – the more I use Excel, the more I need to use Excel. I work on a lot of Power Pivot workbooks these days and sometimes these workbooks need to run a refresh or recalc that can take a bit of […]
Edit 16 May 2015: I now know the exact cause and cure for this problem. See this post here This backup tip is still useful though. This is a follow up to this post where I talked about Power Query and warned to take frequent backups when editing your Power […]
I have come across this problem a few times recently. There was no immediately obvious solution that worked at first. I knew what I wanted to do but I couldn’t get it to work – but now I have a solution and I want to share it for the benefit […]
