Assuming we have the data in the report, the first step is to add a decomposition tree to the report layout. The administrator role also has a high proportion of low ratings, at 13.42%, but it isn't considered an influencer. To add another data value, click on the '+' icon next to the values you want to see. Measures and aggregates are by default analyzed at the table level. You can now use these specific devices in Explain by. Drop-down box: The value of the metric under investigation. In addition to the contribution of each node, the advanced decomposition tree comes with the ability to compare two series values (actual & budget, actual & forecast, current year vs previous Year values, etc.) That means Power BI will use artificial intelligence to analyze all the different categories in the Explain by box, and pick the one to drill into to get the highest value of the measure being analyzed. You might want to investigate further to see if there are specific security features your large customers are unhappy about. The key influencers visual compares and ranks factors from many different variables. If the customer table doesn't have a unique identifier, you can't evaluate the measure and it's ignored by the analysis. In the example below, we look at house prices.
