DAX GROUPBY each group
Hi,
I have a table like below in Power BI:
I want a table which return MAX(Rate) for each group, along with the group i.e. a table like below:
How can I achieve this?
Thanks,
Shiv
Table 2 = VAR __tmpTable = SUMMARIZE('Table31',[Name],"__MaxRate",MAX('Table31'[Rate])) RETURN ADDCOLUMNS(__tmpTable,"__Day",MAXX(FILTER(ALL('Table31'),[Rate]=[__MaxRate]),[Day]))Table31 is my base table.

Maybe something like this:
Measure Rate = MAX([Rate]) Measure Day = MAXX(FILTER('Table',[Rate]=[Measure Rate]),[Day])Put these two measures in a table viz with [Name].

Why we can't use an expression like below:
NewTable = CALCULATETABLE(Table1, GROUPBY(Table1, Table1[Day],Table1[Name], "maxrate", MAX(Table1[Rate])))

"Function GROUPBY sclar expressions have to be Aggregation functions over CurrentGroup(). The expression of each Aggregation has to be either a constant or direct reference the columns in CurrentGroup()"
