Display a formatted value based on a two-value filter

Hi Zacharie 

Download PBIX file with example below

I think this single measure will do it for you.  NOTE that I've create a dummy measure [Revenue_] that doesn't do any conversion betwen currencies but works for the sake of this example.  You'll need to insert your own measure into the code below

Revenue Formatted = 

VAR _rev = FORMAT([Revenue_],"### ### ### ###")

VAR _magnitude = ROUNDDOWN ( DIVIDE ( LOG10 ( [Revenue_] ), 3 ), 0 )

VAR _format = SELECTEDVALUE('Format'[Format])

VAR _currency = 

    SWITCH(

        SELECTEDVALUE('Currency'[Currency]),

        "EUR", "€ ",
        "AED", "AED ",
        "AUD", "A$ ",
        "BRL", "R$ ",
        "SEK", "kr ",
        "USD", "$ ",
        
        "€ "

    )

RETURN

IF(_format = "Long", _currency & _rev


, //ELSE Format = "Short"

    SWITCH(

        _magnitude,

        0, _currency & FORMAT([Revenue_],"#,0"),        -- Integer number
        1, _currency & FORMAT([Revenue_],"#,0,.0#K"),   -- Thousand
        2, _currency & FORMAT([Revenue_],"#,0,,.0#M"),  -- Million
        3, _currency & FORMAT([Revenue_],"#,0,,,.0#B"), -- Billion
        
        _currency & FORMAT([Revenue_],"#,0,,,,.0#T")    -- Trillion

    )

)
