Inspired by the Delta Master BI -a tool that we have worked with for many years and that combines advanced analytics and a great UI- I was looking to realise one of its cool features in Power BI. Delta Master is a brilliant tool but unfortunately has an “enterprise price tag. As we will see we can get pretty close to using one analysis method using Power BI.

The Delta Master feature is called “Power Search” and does a ranking across all dimensions and levels in a multi-dimensional cube (e.g. Analysis Services).

The user can specify a measure e.g. “Revenue” and the method returns a ranking across all dimensions like for example shown here:

This is a great starting point to see what is “driving ” your revenue. In this case the first 2 results are trivial as we are only operating in this market and with one company but from rank 2 it gets more interesting and we see that a customer group has the biggest share of “Revenue” with 80% followed by a product group classification with 78% etc.

A ranking like this is also particularly interesting if it’s on a measure like Actual-Budget variance as it will avoid that I have to navigate through multiple dimensions to find where is the variance coming from. Using the Power Search approach I get the key factors immediately.

Taking this approach further Power Search also allows you to include combinations in the ranking when it gets even more interesting like:

To realise something similar in Power BI you just add the Table visual to your dashboard and drag the attributes that you want to use in the ranking into there:

Power Search


And voila we see an overview of what is driving Revenues across all relevant attributes. To Calculate the share of the total just use this simple DAX calculation:

Share = CALCULATE(sum(Xero_Sales_Data[LineAmount])/CALCULATE(sum(Xero_Sales_Data[LineAmount]),ALLSELECTED()))
