Hey there. I have the same issue. Have you found the solution?

Ugh! I"m going to have to find another community. Can't seem to find actual answers in here very often. Frustrating.

Hi @YonghunLee 

If you means to create unique id in power bi, it is possible as long as for the same name(different people), there are different values in other columns.

You could create index column with DAX as below:

https://community.powerbi.com/t5/Desktop/Create-unique-ID/td-p/677570

For example,create a column below:

Final Rank =
RANKX (
    Table,
    RANKX ( Table, [Primary column],, ASC )
        + DIVIDE (
            RANKX ( Table, [Secondary column],, ASC ),
            ( COUNTROWS (Table ) + 1 )
        )
)

rank as unique id = 
RANKX (
    'Table (2)',
    RANKX ( 'Table (2)', [name],, ASC )
        + DIVIDE (
            RANKX ( 'Table (2)', [column1],, ASC ),
            ( COUNTROWS ( 'Table (2)' ) + 1 )
        ),,ASC,Dense
)
