Index in DAX

[Anonymous]

Hi All,

I want a dynamic DAX that can show me sequential numbers for all my records in table KPI.

The table can be filtered using slicers and so the index should change dynamically.

Hi @Anonymous ,

You can try the following measure to show the dynamic index.

RowNum = 
CALCULATE (
    COUNT ( 'Table'[ID] ),
    FILTER (
        ALLSELECTED ( 'Table' ),
        'Table'[ID]  <= MAX ( 'Table'[ID]  )
    )
)

You can check more details from here.

Best Regards,

@Anonymous , In case of Dax Index, would be Rank most of the time. Rank can column Rank static and Measure Rank Dynamic. But Measure rank to Dynamic, you can use allselected. Also, measure rank is context-sensitive

City Rank = RANKX(all(Geography[City]),[Sales]) // Work for City both with City ID all city Rank is 1
Geography Rank = RANKX(all(Geography),[Sales]) // Work with both CIty and City ID , both are the lowest level
City and ID Rank = RANKX(all(Geography[City],Geography[City Id]),[Sales])// Work with both CIty and City ID

There are also techniques using RANKX although they tend to product duplicates. There are mitigation methods using small random numbers to break ties.
