lap time rankx


I'm a french newbie with PowerBi.

I'm a bit lost with rankx. Here is my problem

For each car number I want to calculate these two columns:

- Lap time ranking

- stint number : each stint ranking (a stint is each time the car go on track, separated per a box entry "B")

here is an example with 2 cars

Re: lap time rankx

Hi @Yannick63,

Based on my test, you could refer to below formula to calculate the rank:

Rank = RANKX('Table1','Table1'[lap time],,ASC,Dense)

But I could not figure out the logic of how to calculate the stint number, could you please offe me more information about it?

Re: lap time rankx

Hello @v-danhe-msft

thanks for your help.



Because my database is with a lot of data I have this error message :

A single value for column ' Lap Time' in table 'Table 1' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result.



The stint calculation is just

1st stint is from 1st lap time until B in box column

2d stint is after the 1st B (Box) you find until the 2d B you find or until next car

I hope it's clear now.
