Power BI What if analysis - powerbi

Question

I have a matrix Power BI visualization which is like
Jan Feb Mar April
Client1 10 20 30 10
Client2 15 25 65 80
Client3 66 22 54 12
I have created 3 what if parameters slicer table (having values from 1 to 4) for each client
For example, If the value of the first slicer is 1 and the second is 2 and the third is 2 then I want
Jan Feb Mar April
Client1 0 20 30 10
Client2 0 0 65 80
Client3 0 0 54 12
That is, it should replace the value with zero. I have been able to achieve that for one client using Dateadd function (by adding month)
Measure = CALCULATE(SUM('Table'[Value]),
DATEADD('Table'[Column], Parameter[Parameter Value], MONTH))
and I have used this measure to display the value, but how to make it work for the other two clients as well .

Answer 1

Let say you have three parameter tables as follows
Parameter1 Parameter2 Parameter3
Value1 Value2 Value3
------ ------ ------
1 1 1
2 2 2
3 3 3
4 4 4
and each of them has its own slicer. Then the measure you are after might look something like this:
Measure =
VAR Val1 = MAX(Parameter1[Value1])
VAR Val2 = MAX(Parameter2[Value2])
VAR Val3 = MAX(Parameter3[Value3])
VAR CurrClient = MAX('Table'[Client])
VAR CurrMonth = MONTH(DATEVALUE(MAX('Table'[Month]) & " 1, 2000"))
RETURN SWITCH(CurrClient,
"Client1", IF(CurrMonth <= Val1, 0, SUM('Table'[Value])),
"Client2", IF(CurrMonth <= Val2, 0, SUM('Table'[Value])),
"Client3", IF(CurrMonth <= Val3, 0, SUM('Table'[Value])),
SUM('Table'[Value])
)
Basically, you read in each parameter and compare them to the month in the current cell.
