I've modified the RDL from http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=525433&SiteID=1 to illustrate the problem I am having setting Interactive Sorts on columns in a Matrix. Using the rdl below you'll see that the 2 interactive sorts in the matrix corner named Cols and Rows are working well. My problem is in adding the Interactive Sorts to the individual CompanyName columns. I’d like to be able to click on a CompanyName and have the CategoryName (rows) sort by the Quantities shown for the clicked CompanyName. Any help in correcting the rdl below would be appreciated.

Clicking on a column header to sort the rows is not supported. Because an end-user sort on a column header means you want to sort all details (when the SortExpressionScope is detail scope) or all inner groups (that correspond to the SortExpressionScope if it's not detail) under that column. Since the matrix row hierarchy is not under the columns, this would be an invalid scenario.
