Total sales based on field parameter

[Anonymous]

Hi, Not sure if it is possible, but id like a column here which based on the parameter selected does a total of the matching grouping: 

So in the case below, now that product group is selected, I need a colum which for A,D,G,J all show the total sales value for "Bike", which is the corresponding product group that they are connected to etc. 
In case I was doing it by sub product group, the total for F and L for instance would show the total for "Bad coffe"

pbix file with data can be found here

Created the following measure: 

Sales by selected parameter = 
VAR _SelectedParameter =
    SELECTEDVALUE ( Parameter[Parameter Order] )
VAR _CurrentDimension =
    SWITCH (
        _SelectedParameter,
        0, SELECTEDVALUE ( DimArticle[Product group] ),
        1, SELECTEDVALUE ( DimArticle[sub product group] ),
        2, SELECTEDVALUE ( 'Fact Sales'[Customer] )
    )
VAR _TotalSales =
    SWITCH (
        _SelectedParameter,
        0,
            SUMX (
                FILTER (
                    ALL('Fact Sales'),
                    RELATED ( DimArticle[Product group] ) = _CurrentDimension
                ),
                'Fact Sales'[Sales Value]
            ),
        1,
            SUMX (
                FILTER (
                    ALL('Fact Sales'),
                    RELATED ( DimArticle[sub product group] ) = _CurrentDimension
                ),
                'Fact Sales'[Sales Value]
            ),
        2,
            SUMX (
                FILTER (
                    ALL('Fact Sales'),
                    'Fact Sales'[Customer] = _CurrentDimension
                ),
                'Fact Sales'[Sales Value]
            )
    )
RETURN
   _TotalSales
