Append tables with same columns using DAX
Hi friends!
Basically is that, i want to merge or append tables that has the same columns (same quantity and same name) using DAX. I know how to do it in Power Query but I read on a post that DAX shows better performance when is about refreshing time than Power Query.
Does anyone knows how to do a calculated table with DAX to merge multiple tables?
Hi AlexisKMX ,
Please try below dax function:
UNION: same as the append feature in Power Query
NATURALINNERJOIN/NATURALLEFTOUTERJOIN: same as the merge feature in Power Query
For more details, you can read related document:
