Mapping Value by max in a group

[Anonymous]

Hi, I am struggling to achieve result below. I've already tried several functions with no result. The idea is to get in each row for a particular group, name of the person who got the max value.

Group	Name	Country	Value	*Top Name
A	Jon	DE	1	Judy
A	Chris	GB	2	Judy
A	Judy	FR	3	Judy
B	Adam	IT	10	Barbara
B	Mike	PL	20	Barbara
B	Barbara	CZ	30	Barbara

Hi @Anonymous 

try new measure

Measure = LOOKUPVALUE(
Table1[Name];
Table1[Value];CALCULATE(max(Table1[Value]);ALLEXCEPT(Table1;Table1[Group]));
Table1[Group];selectedvalue(Table1[Group])
)

Awesome, thank you a lot, it works perfectly. If it's not a big problem, could you share more insights how the CALCULATE works with the SELECTEDVALUE inside a LOOKUPVALUE? I know each one of them, but the combination is what gives me trouble.

Thanks again 🙂

well, lets try. we create a measure that will have a value in each row.

so, selectedvalue - is a value of selected field in each given row.

in tis solution for each row we:

first, looking for a max value for group 

CALCULATE(max(Table1[Value]);ALLEXCEPT(Table1;Table1[Group]));

then make a lookupvalue this MAX value in the same table

and at last we check if this MAX value is about Group in the row (because, it could be a several different groups with the same MAX value)
