Yes, worked great for me too. I just needed to set all the table names in the Biz object like this

 public DataSet GetDataForRouteScheduleReport(int CompanyID, DateTime StartDate, DateTime EndDate)
        {
            // Returns Header DataSet
            DataSet ds = this.GetDataSet("getRouteScheduleReportData", CommandType.StoredProcedure,
                this.CreateParameter("@nCompanyID", CompanyID), 
                this.CreateParameter("@StartDate", StartDate), this.CreateParameter("@EndDate", EndDate));
            ds.Tables[0].TableName = "RouteData";
            ds.Tables[1].TableName = "Cleaners";
            ds.Tables[2].TableName = "Equipment";
            ds.Tables[3].TableName = "Jobs";
            ds.Tables[4].TableName = "JobDetails";
            ds.Tables[5].TableName = "Notes";
            return ds;
        }

and then in the ReportViewer page I used that method.

Kevin actually has this as part of the separate class, I found a link to this class and gave a link somewhere in this thread.
