MDX: Top 10 with filtered members

[r0375557]

I'm creating a report for JasperServer in iReport. I am creating a report with the top 10 companies with most product downloads of the selected products. Users can select in JasperReports which products with a list (parameter {$P{ProductFormat}}).

My dimension for products has the following structure: [Product].[ProductFactory].[ProductType], so input for the parameter for example can be: [Product].[ProductCategory1].[Product1], [Product].[ProductCategory2].[Product2], ... I also want those products available as rows so I can use them as fields in iReport. (product in where is not an option)

SELECT

  NON EMPTY {

    [Measures].[Orders]

  } ON COLUMNS,

  NON EMPTY

     Crossjoin({TopCount({[uSER_COMPANY].[Company].Members}, 10, [Measures].[Orders])}, {$P{ProductFormat}})

   ON ROWS

FROM [Products]

WHERE $P{DateFilter}[/code]

This query return the top 10 companies of all products with the data filtered per products. I want a top 10 companies of the selected products, but I can't get it to work with topcount and as a row.

Thanks.
