Rank values without duplicate ranking

[AlexanderBrueck]

Dear Community,

I tried to get the ranking displayed in column "Rank" by using Rankx - without success.

The idea is to rank the amounts in column "€" for each month. When there are duplicate values (e. g. 2.950 € in March) the first apperance should be 3 for instance and all following rankings for the the values should get the next higher number - in this case 4.

Is there any solution for this? Thanks in advance!

We can take help from an Index column to manage duplicates

First add an index columm from Query Editor. Then this DAX calculated column

Rank Column =
RANKX (
    FILTER (
        Table1,
        Table1[date].[Month] = EARLIER ( Table1[date].[Month] )
            && Table1[date].[Year] = EARLIER ( Table1[date].[Year] )
    ),
    [Euro]
        - [Index] / POWER ( 10, 9 ),
    ,
    DESC,
    DENSE
)

Hello,
How to avoid duplication on a measure?
With your technique, "it is impossible to determine a unique value for the INDEX column".

Thanks
