RANKX Function in Power BI

The RANKX function in Power BI works similarly to the one in the excel RANK functionExcel RANK FunctionExcel Rank formula gives rank of a given data set of numbers. The rank function was an inbuilt function in Excel 2007 and older versions; we now have Rank.Avg and Rank.Eq functions in subsequent versions above 2007.read more and assigns rank based on numbers of the specific or mentioned column. Below is the syntax of the RANKX Power BI DAXPower BI DAXIn Power Bi, DAX stands for Data Analysis and Expression and is a functional language that represents all of the functions in Excel and Power BI. Formulas in Power BI can be created using the DAX language.read more function.

Table: We need to specify based on which table you are ranking.

Expression: We must supply the column name here based on which column you are ranking.

Value: This is a bizarre argument unless you are ranking at the advanced level. This argument will not put to use. So don’t worry about this argument at this point in time.

Order: In this argument, we can mention whether the ranking is in the form of ascending or descending order. The default parameter is in descending order, i.e., it will rank the top value 1, and so on.

We can supply two arguments here: TRUE or FALSE. TRUE is for ascending order, i.e., the lowest value is 1. If you supply FALSE, it will rank in descending order. Therefore, the highest value is 1.

Ties: This is the important thing you need to learn. In this argument, we can specify what should be done if there is a TIE between two values.

  • If you SKIP this, the rank after the tied value will be the rank of the tied value plus a count of tied values. So, for example, if there are 3 values tied at 5th rank, then the next rank will be 8 = (5+3).If you supply DENSE as the option, the next value after the tied rank will be the next rank of the tied values. So, for example, if there are 3 values tied at 5th rank, then the next rank will be 6 = (5+1).

Example of RANKX Function in Power BI

Below is an example of a RANKX function. To apply this function in Power BI, we have created the below data in Excel.

It is the data of marks obtained from 6 subjects. Then, based on different parameters, we will rank these students.

Copy and paste the data directly to Power BI. Else, you can copy it to an Excel file and then import it to Power BI as an Excel file reference. So, you can download the Excel workbook template from the link below, which is used for this example.

We have directly uploaded the data to Power BI.

The first student, “Janet Martin,” was ranked as 1 based on the total score column but based on “Sub 3,” he is ranked as 4.

So, we have a ranking based on the scores of each student.

Note: We have done so much formatting to this table. You can download the Power BI RANKX template from the link below and apply each formatting technique as applied.

Things to Remember

  • We can skip optional arguments by entering a comma.If we want different ranking techniques in case of a tie, we must use the “TIE” argument of the function.The first two arguments are mandatory, and the rest are optional.
