Hi Amit,

I need code for calculated table not in the query editor. Kindly help me for DAX code for calculated Table.

@Murali777 , DAX code

filter(addcolumns(Table, "_Max", maxx(filter(Table, Table[Email] = earlier([Email])), [registration Date])), [_Max] = [registration Date])

or

new Table  =

Var _1 = addcolumns(Table, "_Max", maxx(filter(Table, Table[Email] = earlier([Email])), [registration Date]))

return

calculatetable(_1, filter(_1, [_Max] = [registration Date]) )

Hi Amit,

Thanks for your code and your code is almost working. but my challenge is, i'm having bunch of columns and it returns all the column. 

I want only the 3 columns (Email, First Name, Last Name) in the calculated table.
