Exclude specific calculation from subtotal and grand total lines - powerbi

Question

I have this table :
And I want to calculate for each day and for each group 1and2 % which is
(Attribute1/Attribute2)*100
But I don't want to include 1and2 % in Group Subtotal neither on total
I created a new table :
Table3 = UNION(DISTINCT('Table'[Attributes]);{{"1and2 %"}})
And i made this mesure to calculate 1and2 %:
Measure =
SUMX (
DISTINCT ( 'Table3'[Attributes] );
SWITCH (
'Table3'[Attributes];
"1and2 %"; DIVIDE (
CALCULATE ( SUM ( 'Table'[Value] ); 'Table'[Attributes] = "Attribute1" );
CALCULATE ( SUM ( 'Table'[Value] ); 'Table'[Attributes] = "Attribute2" );
0
) * 100;
VAR a = 'Table3'[Attributes]
RETURN
CALCULATE ( SUM ( 'Table'[Value] ); 'Table'[Attributes] = a )
)
)
And this is the result I'm getting :
I want to exclude 1and2 % (and every Attribute containing % in the future) from group subtotal and the total.
I'm really new to PowerBI and not really familiar with Excel-like formulas.
Can anyone please help me up with that?
Regards

Answer 1

Someone from PowerBI forum gave me this solution and it's exactly what im looking for:
Create another mesure using the existing :
Measure 2 =
VAR __Table =
ADDCOLUMNS(
SUMMARIZE(
'Table 3',
[Group],
[Attribute],
"__Measure",[Measure]
),
"__IncludeInTotals",SEARCH("%",[Attribute],,-1)
)
RETURN
IF(
HASONEVALUE('Table 3'[Attribute]),
[Measure],
SUMX(FILTER(__Table,[__IncludeInTotals] = -1),[__Measure])
)

I think you can get what you want if you only calculate the 1and2 % part when that's the only thing in the filter context and do a normal sum otherwise.
Measure =
IF (
SELECTEDVALUE ( 'Table3'[Attributes] ) = "1and2 %";
DIVIDE (
CALCULATE ( SUM ( 'Table'[Value] ); 'Table'[Attributes] = "Attribute1" );
CALCULATE ( SUM ( 'Table'[Value] ); 'Table'[Attributes] = "Attribute2" );
0
) * 100;
SUM ( 'Table'[Value] )
)
For the subtotals and grand total, SELECTEDVALUE returns blank so the condition fails and you just get the sum.
