Issue with TOPN and RANKX with no ties

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.
