Unique - Complex DAX Challenge for Matrix Visual Specific for Columns & Total

[ScottBrown]

This one has got me perplexed.

How do you create the DAX Measure Value for a matrix that does the following for the Totals?

• Does the normal Summing for the columns
• Does a special calculation for the Total column

Example Table Would Be

• DAX Total column formula is (Current + Mid-Tier) - Legacy

Person	Legacy	Mid-Tier	Current	DAX Total
A	6	0	4	-2
B	4	1	3	0
C	6	3	5	2
TOTAL	12  (Sum Total)	4  (Sum Total)	12  (Sum Total)	4  (Calc Total (C+M)-L

Hi @ScottBrown ,

Please try the following formula:

Measure = 
var _sum = SUM ( 'Table'[Value] )
return 
    IF (
        ISFILTERED ( 'Table'[Category] ),
        _sum,
        _sum - 2 * CALCULATE ( SUM ( 'Table'[Value] ), 'Table'[Category] = "Legacy" )
    )

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.

@ScottBrown , if these are value of column say Tier and you column of value is value

new measure =

if((isinscope([Tier])), sum(Table[Value]) ,
Switch(true(),
max(Table[Tier]) = "Legacy" , -1 * sum(Table[Value]) ,
sum(Table[Value]) ) )

If they are measure 

then new measure

([Current] + [Mid-Tier]) - [Legacy]
