Ranking Averages by Criteria - powerbi

Question

here is the deal... (actually I've solved it but I am sure there is an easier way)
my table is :
Department ID
Criteria 1
Criteria 2
Criteria 3
DEP 001
4
5
3
DEP 002
5

5
DEP 003

DEP 004

I am trying to find the top 1 average in each criteria.
I've used unpivot, creating new table and then calculated column to find the result.
First Unpivoting
let
Source = YourTableName,
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Department ID", type text}, {"Criteria 1", Int64.Type}, {"Criteria 2", Int64.Type}, {"Criteria 3", Int64.Type}}),
#"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"Department ID"}, "Attribute", "Value")
in
#"Unpivoted Other Columns"
Second calculated Table :
Max Avg =
VAR _cr1 =
SUMMARIZE (
'YourTableName (unpivoted)',
'YourTableName (unpivoted)'[Department ID],
'YourTableName (unpivoted)'[Attribute],
"Criteria Avg",
CALCULATE (
AVERAGE ( 'YourTableName (unpivoted)'[Value] ),
ALLEXCEPT (
'YourTableName (unpivoted)',
'YourTableName (unpivoted)'[Department ID],
'YourTableName (unpivoted)'[Attribute]
)
)
)
RETURN
_cr1
and finally the calculated rank column and filter by 1
RANK =
RANKX (
FILTER (
'Max Avg',
'Max Avg'[Attribute] = EARLIER ( 'Max Avg'[Attribute])
),
'Max Avg'[Criteria Avg],
,
DESC,
DENSE
)
expected result is :
Can you suggest an easier way ?
This is PBix file where you can work on to suggest a faster way

Answer 1

Only by creating a couple of complicated measures. BTW, I'd always reshape data in PQ rather than DAX. Here is an alternative:
Create a criteria table.
Create a measure:
Attribute =
VAR a = ADDCOLUMNS(
SUMMARIZE(YourTableName, YourTableName[Department ID]) ,
"#crit1", CALCULATE(AVERAGE(YourTableName[Criteria 1])),
"#crit2", CALCULATE(AVERAGE(YourTableName[Criteria 2])),
"#crit3", CALCULATE(AVERAGE(YourTableName[Criteria 3]))
)
return
SWITCH(SELECTEDVALUE(Criteria[Criteria]),
"Criteria 1", MAXX(a, [#crit1]),
"Criteria 2", MAXX(a, [#crit2]),
"Criteria 3", MAXX(a, [#crit3])
)
Add to a table visual
