    Hi, giordafrancis 

    I only know how to create this table in two steps. I could not find a way to create it in one step.

     

    step 1. create a Table

     

    new table = SUMMARIZE('Table', 'Table'[FYear])
     
    Step 2. create a calculated colum
     
    idx =
    CALCULATE (
    SUMX ( 'new table', 1 ),
    FILTER ( 'new table', 'new table'[FYear] <= EARLIER ( 'new table'[FYear] ) )
    )

      Here's how to do it in one go:

       

      [New Table] =
    addcolumns(
        distinct( YourTable[FYear] ),
        "idx",
            var CurrentFYear = YourTable[FYear]
            return
            countrows(
                summarize(
                    filter(
                        YourTable,
                        YourTable[FYear] <= CurrentFYear
                    ),
                    YourTable[FYear]
                )
            )
    )
