DAX for Power BI training course contents

If you've been on our Introduction to Power BI course (or you've taught yourself how to create Power BI reports), you'll be asking yourself questions like this:

My financial year ends in March - how can I show this in my reports?
How can I compare total figures for this month with the same period last year?
When I drill-down to show figures for a particular region, how can I show the region name as a page title?
How can I show figures for each group as a percentage of the total for all groups?

Unfortunately while learning Power BI was relatively easy, you now need to understand how to create calculated columns and especially measures, which is less straightforward. This two-day course includes:

What row context and filter context are, and why they are so important to understanding DAX
The best way to create measures and calculated columns using DAX
How to use the CALCULATE function to modify your filter context (and what this means)
Creating and using a separate calendar table to work with dates (including strategies for coping with multiple date fields)
Using the built in DAX date functions like TOTALYTD, SAMEPERIODLASTYEAR (and many more like this)

You should avoid this course if you're don't consider to be good with numbers!

What other people have said

Our thanks to everyone who agreed to share their thoughts. All of the following reviews are from the last 3 calendar years:

"A great course! The trainer is so knowledgeable but explained everything in terms I could understand. He also spoke about examples which would fit into my line of work, this really helped to add perspective and depth to my understanding."

Claire Payton (Government Internal Audit Agency (GIAA))

"This was perfect for what I needed. Content just right. I was slightly worried that it might be very dull, but it wasn't at all. Our trainer did an excellent job of making it interesting and engaging, keeping us all involved and answering various difficult questions. Felt both well prepared AND responsive. Pacing good too."

Matt Page (Institution of Occupational Safety and Health)

"Absolutely loved the course. Fab and really engaging trainer. The pace was good and the way the courses are set up makes it really easy to follow along with the exercises. I have attended a Wise Owl course previously and found the trainer really engaging and the course really useful, so I was hopeful that I would have just as good an experience with this course - which I did :)"

Amanda Wilding (ReAssure UK Services Limited)

"My tutor was extremely good, very detailed and adapted the lesson, where necessary, to match my ability. I even asked if we could include a task where I would need to troubleshoot DAX to see what was missing and this was included with ease. Thanks again!"

Scott Castro (Addleshaw Goddard)

"Another helpful course – thank you!! An excellent trainer – very patient and friendly, and adapted the course to the audience’s needs. I love the small class size – just three this time, two last time – facilitates a much more engaging & interactive couple of days. Once I’ve got a bit more used to DAX, I plan to attend one of your Advanced Power BI courses. See you again soon!"

Faye Cowley (The Outward Bound Trust)

How our training courses work

Below are some notes on how Wise Owl courses work, to help you decide whether they're for you or not.

What you'll need

If you book on a classroom course, the only thing you need to bring to the course is ... yourself! We even provide a notepad and a suprisingly nice pen for you to take notes with.

For online training you'll need two things:

A good internet connection (otherwise you'll have a frustrating time); and
A second screen (a requirement, not a nice-to-have!)

You can see full details of our online course requirements here.

When you book a place

If you book a place on one of our courses:

For classroom courses we will send out a joining email. That's it!
For online courses we will get in touch to organise a half-hour pre-course check to iron out any connection problems before the course (rather than during it).

Whatever type of course you book, we will also send you out a reminder a few days before the course is due to take place - not that (we hope) you'll have forgotten!

What you won't need

For classroom training, you won't need a computer - we (obviously) will provide that. However, you're welcome to use your own laptop if you prefer, providing that you have the correct software installed.

For online training you will need a computer, but you won't need to have any software installed. This is because you'll use Windows Remote Desktop to connect to our computers, and these will have all of the necessary files and software installed.

The start of the course

For online courses you will be able to join up to half an hour before the course begins. This will give you time to:

familiarise yourself with the set-up;
meet your trainer; and
get to know the other delegates!

For classroom training it's always nice if people arrive a bit early too, to give people time to meet each other (and drink coffee).

You'll be given a full colour courseware manual, an exercise booklet to go with the course and a USB stick for taking course files away (we'll post all this to you for online courses).

After the course

After the course finishes you'll receive a digital certificate proving your attendance (we will gladly send a paper copy on request also).

We don't have any formal arrangement for answering questions after the course, but if you get stuck on something and email your trainer they should (and nearly always do!) respond as quickly as their training schedule allows.
