You have heard of the 80:20 rule (Pareto) Power BI has a TOPN function in DAX This guide shows you how to start using it https://www.selectdistinct.co.uk/2023/06/28/topn-in-power-bi/ #powerbi #topn #businessintelligence In the world of data analysis, having the ability to efficiently rank and prioritize information is crucial. This is where the TOPN function in Power BI comes into play. By utilizing this powerful ranking function, analysts and data professionals can gain valuable insights from their datasets. The TOPN function, short for "top n," allows users to identify and retrieve the top or bottom records based on a specified criteria. This function is particularly useful when dealing with large datasets that require quick and accurate analysis. With Power BI's extensive capabilities, the TOPN function can be utilized through its native DAX (Data Analysis Expressions) formula language. By incorporating this formula into your Power BI reports and dashboards, you can effectively sort and filter data to highlight key trends, outliers, or patterns. The importance of the TOPN function lies in its ability to streamline decision-making processes by presenting relevant information in a concise manner. Whether you are analysing sales figures, customer satisfaction ratings, or any other dataset, being able to quickly identify the top performers or underperformers can greatly impact strategic decision-making. In this section, we will delve deeper into understanding how the TOPN function works within Power BI and explore real-world use cases where it can be applied effectively. So let's dive in and unlock the full potential of this essential feature in Power BI!

- 1. Power BI Tips and Timesavers TOPN measure in Power BI
- 2. You have heard of the 80:20 rule (Pareto)? This principle suggests that typically 80% of value comes from the top 20% of your data In Power BI we can focus the attention of readers on the most significant pieces of data that drive almost all of the value, using the TOPN function
- 3. Top 5 in a Measure Although Power BI has a built-in Top N filter feature It is often useful to be able to show that value as a measure and what percent of the whole it represents This guide shows you how to do it
- 4. Step by Step Create a measure to aggregate sales for the top 5 products We create a Variable to identify the top 5 products, and a separate variable to aggregate the sales amount This makes the DAX easier to follow Top 5 Products Sales = VAR TopNProducts = TOPN ( 5, SUMMARIZE(Sales, 'Product'[Product],"SALESVALUE",sum(Sales[Sales Amount])), [SALESVALUE],desc ) VAR Result = CALCULATE ( SUM(Sales[Sales Amount]), TopNProducts ) RETURN Result
- 5. DAX Breakdown SUMMARIZE creates subtotals, in this case a column with each ‘Product’ and a second column for the total sales SUMMARIZE(Sales, 'Product'[Product],"SALESVALUE",sum(Sales[Sales Amount])) TOPN – The ‘5’ sets how many top rows to return We use the summarise row to define the data rows (see above) The last row defines the field to sort by (SALESVALUE in Descending order) TOPN ( 5, SUMMARIZE(Sales, 'Product'[Product],"SALESVALUE",sum(Sales[Sales Amount])), [SALESVALUE],desc
- 6. DAX Breakdown Next we calculate the Sum of Sales for each Product in the Top N products VAR Result = CALCULATE ( SUM(Sales[Sales Amount]), TopNProducts )
- 7. Top X in a Measure We have then used this measure on a card to highlight how much of the total the top X products represent We added a simple secondary measure showing what percentage this is We then created similar for the bottom 20 products And Finally added these to the chart
- 8. Having the ability to focus on the top few drivers of performance the TOPN function is a powerful way to eliminate noise from insignificant items TOPN in Power BI is easy to learn and apply once you understand the syntax Keep an eye out for the more advanced use of this with an amendable parameter in the coming weeks
