![]() This means TopN of 10 might have more than 10 rows if there are two items with the same expression results in the top 10 list. However, in case of ties, it bring all ties. TOPN usually should return a table with only N rows. There are no function names as BottomN, but you can simply change the order in the TOPN to ASC, and then you will get BottomN, as below Get bottom rows from a table using TOPN function in Power BI When N is more than N! Get the top items with their sales amount using TOPN and Summarize Bottom N The whole Summarize section used as the input table to TOPN function. To learn more about Summarize read my article here. We can use a function such as Summarize to build a virtual table with the Sales amount in it, and then get the top items from it. ![]() ![]() The example above doesn’t show the sales amount, so there isn’t an easy way to test it. for example, the expression below is the top two product colors based on the sales TopN 2nd example =ĬALCULATE(SUM(FactInternetSales)) The input table of the TOPN function can be any function that returns a table as well. ) Using TopN to create the top 10 products based on their sales in Power BI TopN 1st example =ĬALCULATE(sum(FactInternetSales)) TOPN can be used as simple as below to give us the top 10 products based on the sales. order (optional): The selection should be from top or bottom of the table? default is DESC which means TOP, if it changes to ASC it would act like bottom.Īs you can understand from the above, the TOPN function is not just used to get the top items, but also the bottom items (based on the order parameter).orderBy_expression: The expression used to order the items of the table so that the top or bottom items be picked.table: the input table to get the subset of items from it.n_value: The count of items you want to pick either from the top or bottom of the input table.TOPN function can be used like this: TOPN(,, , ]…]) TOPN is a tabular function in DAX, and the table it returns is a subset of the input table but only the top (or bottom) items of that table based on evaluation of an expression.
