Rank Issue

[Anonymous]

Hi All,

I am trying to rank a value field, but I am getting the rank as below.

Can Someone explain me what I am doing wrong here, how can I resolve this.

Thanks in advance!

Hey,

this is because empty values (NULL) are treated as 0 (zero), for this reason there are a lot of rows ranked with the value 13.

This behavior is explained here:

If you want to avoid this, you have to make sure that rows with an empty value have to be filtered out.

Hope this helps

Hi TomMartens,

Thanks for your input,I am able to get the expected data except that my Rank is duplicated due to ties. Is there any

workaround to break the ties and get the rank in sequential order(38,39,40...)

You can break ties using something similar to my post in this thread:

https://community.powerbi.com/t5/Desktop/How-to-Rank-a-list-based-on-2-values-double-rankX/td-p/44008

I think your measure will look something like this.

• TableForRanking refers to the table over which the ranks are computed - this could be an expression (filtering out blanks for instance). You may want to assign this to a variable.
• [Primary Measure] is I think [Calculation 1] in your case.
• PhysicalTable should be replaced with the name of the physical table that contains the date column.

Rank with ties broken =
RANKX (
    TableForRanking,
    RANKX ( TableForRanking, [Primary Measure],, ASC )
        + DIVIDE (
            RANKX (
                TableForRanking,
                PhysicalTable[Date],
                CALCULATE ( MAX ( PhysicalTable[Date] ) ),
                ASC
            ),
            ( COUNTROWS ( TableForRanking ) + 1 )
        )
)

It might be easier for you to post more details on the table/measure names or a sample pbix file to get the code exactly right.
