DAX Calculated Table

[bwelsh]

I'm trying to create a calculated table based on a table with a colum for USER ID and EVENT ID (among others).

I need to create a table showsing disting USER ID's for only specific EVENT ID's. 

I've been trying to use the filter and disting functions but I'm not getting anywhere. Any help would be appreciated.

EDIT:

I think I may have figured this out with SUMMARIZECOLUMNS: 

CALCULATED TABLE = SUMMARIZECOLUMNS('Original Table'[USERID], FILTER('Original Table', 'Original Table'[EVENTID] = "SPECIFIC EVENT ID"))

Hi @bwelsh,

Please use the formula below to create new table.

CALCULATED TABLE = DISTINCT( SELECTCOLUMNS(FILTER('Original Table', 'Original Table'[EVENTID] = "SPECIFIC EVENT ID"),"EVENTID",'Original Table'[EVENTID],"SPECIFIC EVENT ID",'Original Table'[SPECIFIC EVENT ID]))

Best Regards,
Angelia

here are the steps:

- click edit query

- select both user id and event id column

- right click on the header and click remove duplicates

you will get disctinct rows

Wouldnt this modify the original table though? 

I'm trying to create a seperate table.

you can make duplicate of original table and then do the distinct on that, right click on original table and click "duplicate"
