Dynamic Summarized table - selected count

Hi PGY 
Please follow the method described in the attached file. THe solution is based on the assumption that Priority column is of integer data type and contains consecutive values like { 1, 2, 3, ..... }

You will need to have a separate and disconnected table for slicing that contains the priority name and number.

Distinct Count = 
SUMX ( 
    VALUES ( Priority[Priority] ),
    VAR CurrentPriority = Priority[Priority]
    VAR PreviousPriorities = FILTER ( ALL ( Priority[Priority] ), Priority[Priority] < CurrentPriority )
    VAR CurrentMembers = CALCULATETABLE ( VALUES ( Input[Member] ), Input[Priority] = CurrentPriority )
    VAR PreviousMembers = CALCULATETABLE ( VALUES ( Input[Member] ), Input[Priority] IN PreviousPriorities )
    RETURN
        COUNTROWS ( EXCEPT ( CurrentMembers, PreviousMembers ) ) + 0
)

% Local = 
VAR Numerator = CALCULATE ( [Distinct Count], Input[Origion] = "Local" )
VAR Denomimator = [Distinct Count]
RETURN
    DIVIDE ( Numerator, Denomimator ) + 0

*UPDATE

The solution is updated fixing the Total
