create index with measure

Hi selected_ ,

For the rankx function, the basis for processing the same ranking, skip stands for sparse ranking, and the next ranking is equal to the number of all previous rankings + 1; dense stands for dense ranking, which only accumulates the ranking, regardless of the number. 

Therefore, only the following two results can be obtained for the rank function. If you want to get a continuous and uninterrupted ranking. You can create a column index after sorting to get the desired result.

C1 = RANKX('Table (2)',[Value],,ASC,Dense)

C2 = RANKX('Table (2)',[Value],,ASC,Skip)

You can use the Performance Analyzer to view the operating status of the created calculated column and measure to optimize.
