Hi Erdal,
According to your description, you have a matrix report and you want to get percentage of two different column in this report. Right?
In Reporting Service, we can’t just use ReportItem function or aggregation function with scope string to calculation when we are working in a matrix because the columns of matrix are dynamic. So we need to define some functions in custom code and do calculation
by calling those functions. Your scenario has been tested in our local environment. Here are some steps and screenshots for your reference:
Add the custom code below into your report:
Dim Shared Num1 As Integer
Dim shared Num2 As Integer
Public Function GetPA(PA as Integer, Type as String) 
If Type = "Male" Then
   Num1=PA
ELSE If Type="Female" Then
   Num2=PA
End If 
Return PA 
End Function
Public Function GetMalePct()
Return Num1/(Num1+Num2)
End Function
Public Function GetFemalePct()
Return Num2/(Num1+Num2)
End Function
Ps: We notice that Total PA=Male PA +Female PA. So we use “Num1+Num2” in the functions that we define in the custom code instead of using “SUM(Fields!PA.Value)” in expression.
Put the expression below into the PA textbox in Gender group:
=Code.getPA(SUM(Fields!PA.Value),Fields!Gender.Value)
Put the expression below Female textbox within Gender Percentage:
=Code.getFemalePct()
Put the expression below Male textbox within Gender Percentage:
=Code.getMalePct()
Save and preview, the matrix and result looks like below:
