Hi @emilypinhasi,


For your scenario, I'm afraid that DAX may not achieve that. 


Why not try in Query Editor?


We usually split column with comma in Query Editor.

If you still need help, please share some data sample as table and your desired output so we could help further on it.

thanks for the help

i cant use the query editor cause ive created the column using dax


maybe ill describe the bigger problem

i have 3 tables:
teams table: column teamName

epics table: columns: key, teams

stories table: columns: epicKey, team


foreach story there is one team

im trying to populate the epics table so foreach key, get all the distinct teams from stories (related with the epicKey)

later i need to use the teamName as slicer to filter through the epics


hope this makes sense
