Get the previous value of calculated column

[Kev74]

I am stucked in a problem during a few days, 

So my problem is I want to retrive the data of the previous row of my same calculated column, but the problem If i create an another column and make LOOKUP in order to retrive the previous row and with this same column to retrive the current row , I will get a circular error dependancy... 

I don't have any ideas how to ride about this problem ?

This is the problem in Excel to better understand (I want make the same thing than N column) :

If you want more details, please say me, thanks you

Hi Kev,

The EARLIER DAX function can help you with this. You will also need to create a numeric Index column.
In the below example, you can see I can calculate the cumulative sum of the row using the EARLIER function. You can change this aggregated function to find MAX, MIN or AVERAGE of the list up until the row you are on.
