Hi Anonymous 

Seems like you'd wanna get the TOPN based on different category : Customer/Others, and show it in the matrix/table. but the category should be ranked as you wish by Custmer>Others, right?

You might refer to rank by multiple columns:

I modified the measure as:

Measure 4 = 
VAR t =
    SUMMARIZE (
        ALLSELECTED ( 'Table (4)' ),
        'Table (4)'[Code Group],
        'Table (4)'[Name],
        'Table (4)'[Rank],'Table (4)'[Sales]
    )
RETURN
    COUNTROWS (
        FILTER (
            t,
            ISONORAFTER (
                    'Table (4)'[Code Group], SELECTEDVALUE ( 'Table (4)'[Code Group]), ASC,
'Table (4)'[Sales],SELECTEDVALUE('Table (4)'[Sales]),ASC
            )
        )
    )

That the code group ranks by asc, and sales ranks by desc:
