SSRS - Error: Subreport could not be shown

I tried this for the second subreport, Table2, but no subreport for Table2 was displayed:

METHOD SubReportEventHandler(sender AS OBJECT, 
       e AS SubreportProcessingEventArgs) AS VOID
    LOCAL oDS   AS ReportDataSource
    LOCAL table AS datatable
    // fill table here with the appropriate data
    oDS                 := ReportDataSource{"SFMSales",Table}
    e:DataSources:Add(oDS)
oDS                 := ReportDataSource{"SFMSales",Table}
   e:DataSources:Add(oDS)
oDS := ReportDataSource{"SFMSales",Table2}

   e:DataSources:Add(oDS)

Both subreports are in the same directory. How shall I code for the second subreport inside the SubReportEventHandler?
