Hi,
I want to write group by function in Dax. SQL is this ;
SELECT
A,B,SUM(C)
FROM Table
GROUP BY A,B
How to write group by for 2 columns in Dax or SSas ?
@Anonymous , If you have these columns ina table, you can simply put those to a visual , with A and B as not summarized and sum(Table[C])
That will work. If you want to create a new table then use summarize

https://docs.microsoft.com/en-us/dax/summarizecolumns-function-dax
https://docs.microsoft.com/en-us/dax/groupby-function-dax
summarize(Table, Table[A], Table[B], "_C", sum(Table[C])
@Anonymous
try SUMMARIZE() function
https://docs.microsoft.com/en-us/dax/summarize-function-dax
New Table = SUMMARIZE(Table, Table[A], Table[B], "SumC", SUM(Table[C]) )
