You can amend the rows snippet to use the GENERATE function:

SELECT 
  NON EMPTY 
    {[Measures].[Actual Retail Value]} ON 0
 ,NON EMPTY 
    GENERATE( 
     [DimBrands].[Brand].[Brand].ALLMEMBERS AS B
    , 
     TopCount(
          B.CURRENTMEMBER
         *[DimPartners].[Partner].[Partner].ALLMEMBERS
         *[DimSKU].[XXX Desc].[XXX Desc].ALLMEMBERS
       ,5
       ,[Measures].[Actual Retail Value]
      )
    ) ON ROWS
...
...
