    Hi Anonymous ,

    The field [E] is a fact field in the table or a measure? It is a measure, could you please provide its formula? Please create a measure as below and check if you can get the correct rank values...

     

    RANKING = RANKX ( ALLSELECTED ( 'Table' ), CALCULATE ( SUM ( 'Table'[E] ) ),,, DENSE )

     

    In addition, you can refer the following threads to solve your problem.

    RANKX Always Returns 1

    Rank Product =
RANKX (
    ALL ( MyData[Product] ),
    CALCULATE ( SUM ( MyData[Quantity] ), ALLEXCEPT ( MyData, MyData[Product] ) )
)

    Rankx all return 1

    Total Sales = SUM ( sales[sales amount] )

SalesRank = RANKX ( ALLSELECTED ( sales[employee number] ), [Total Sales] )

     

    If the above one can't help you get the desired result, please provide some raw(fake) data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.

H =
RANKX(
    ALL(TableName),
    TableName[E],
    ,
    ,
    DENSE
)

 

i tried and it works like this:

    If I am doing it without the aggregation on the TableName[E] then it shows me the following error

     

    A single value for column ColumnName in Table TableName cannot be determined and not allowing me to move forward. However, if I am applying the aggregation it still shows RANK as 1 for all of the rows.

      the code is used to create a new column. Are you creating a measure?

        I am not creating a measure, it is an exisiting column, but if I am not using Aggregation DAX like SUM it gives me the above mentioned error.
