Add new filter outside ALLEXCEPT

Hi, Anonymous 

According to your description and sample data, I can roughly understand your requirement, I think you can try this measure:

Share of Trade =
VAR _TotalMarketSales =
    CALCULATE (
        SUM ( 'Table'[Sales] ),
        FILTER (
            ALL ( 'Table' ),
            [Category] = MAX ( 'Table'[Category] )
                && [Market] = "Total Market"
        )
    )
RETURN
DIVIDE ( SUM ( 'Table'[Sales] ), _TotalMarketSales )

You can set the measure format to "Percentage" like this:

Then you can create a table chart and place and set the visual like this to get your expected output:

And you can get what you want.

If this result is not what you want, you can post some sample data(without sensitive data) and your expected result.
