Power BI is becoming popular. Therefore, many companies are interested in considering a Power BI Pilot project as a proof of concept. While interacting with customers, I have noticed that many such pilots fail. The failure is NOT due to the capabilities of the product, but due to other factors which are controllable. In this article, I have listed a process which prevents common errors and improves the credibility of the outcome.
PowerView button missing in Excel 2016 – Insert tab? It it visible in 2013. Here is how you add it.
A brilliant new feature is now available in Power BI – Split column into rows. To understand why we need it, you must go and read the article – Analyzing badly captured Survey data or feedback forms. This method used Power Query concepts of Split and Unpivot. Now these have been combined into a single, intelligent command called Split columns into rows. It sounds confusing at first. But soon you will realize that it is an amazing tool. Learn it just 4 minutes.
Raw data looks like this
And you get a report like this. No need to use formulas or do any manual work.
You must have the May 2017 update for Power BI Desktop installed.
This is a short post. It is like an FYI mail. Excel never understood any dates before 1900. We got used to that limitation over the decades. But Power BI does understand Dates before 1900. The best part is, you do not have to take any specific action. It just works.
Here is the raw data and the Power BI output.
If you try this in Excel, it just will not work. Now that you know this, starting using Power BI with Dates before 1900.
Mind you, the Power BI documentation says that the earliest limit is 1900. It still works for dates before 1900. Drill down is also supported. Here is the same data at Day level.
This ability may make historians and archeologists partially happy. There time scales are huge and Power BI does not support that much of a range. But still, it is an improvement worth knowing about.
As you know, I recently published a Power BI Desktop course on Udemy. A few days ago, I received a message from a potential student, Andrew, asking whether taking this course would help him. He wanted to know why Excel-based Power BI is not covered in my course.
This keynote was delivered at the CIO Crown event in Mumbai (India), August 2016. 200+ CIOs attended the session. It was an honor to showcase the power of Office365 to a highly motivated and intelligent audience… love it!

I am happy to announce that my first detailed training course is now up and running at Udemy. It is about Power BI. But it starts with what you already know – Pivot Tables. That is why the course is called Pivot Table to Power BI.
Here is an interesting way to learn two things in one go. While creating the Power BI course for UDEMY, I created lot of explanatory videos. One of the DAX functions which is difficult to understand is the RELATEDTABLE function. So here is a dual video which explains DAX RelatedTable animation. 8 minutes.
Power BI and Power Map support mapping your own data using Latitude and Longitudes. Lat-longs are available in various formats. Power BI supports only decimal format. Unfortunately lot of data still comes with the DMS format Lat-Longs. I created a simple tool: Power BI Lat Long Converter. Use it do perform bulk conversions quickly.

Quick Calc in Power BI (Desktop as well as Portal) is a handy feature. Similar to Show Values As in Pivot Tables.
How to use Quick Calc in Power BI
When you add a measure in the value area, it can be shown as % of Grand Total. Just open the dropdown next to the field and choose Quick Calc.
In the dialog, choose the summarization as desired and then choose Percent of of grand total option from the Show Value As dropdown. Here is the result. I have added the same column twice. Once to show the actual and other as % of total.
With little bit of tweaking of formatting options in Power BI designer, nice looking reports can be created. One of the most common complaints is that the default font size is too small. That can be changed by going to the General section of formatting area.
The Show Values As dropdown has only one option as of now. Of course, it is nothing compared to the Pivot Table Show Values As capability – which offers 14 options. I am sure more options will be added to Power BI soon.
Eliminates a measure
Without Quick Calc in Power BI, you would have to create a measure for the % Total with the following syntax.
SUM ( Query1[Likes] ) / CALCULATE ( SUM ( Query1[Likes] ), ALLSELECTED () )
Or better still, to avoid DIV/zero error in a single command:
SUM ( Query1[Likes] ),
CALCULATE ( SUM ( Query1[Likes] ), ALLSELECTED () ),
The base formatting in Power BI itself is rather primitive at this point of time. This code was formatted using the amazing tool created by Alberto Ferrari and Marko Russo called Dax Formatter. You just copy paste valid DAX code there and it formats it automatically. Output can be an image, HTML or Word. API also available.
Power BI Udemy Course coming very soon
Power BI is becoming more and more powerful day by day. It is time everyone got to know about it. It is the next natural progression from Pivot tables. It is not just easy to use. It gives you more capabilities which you have never had before – and that too with lesser effort.
As promised, the detailed Power BI course is almost ready. It will be released in the near future. Watch this place for further announcements.
