How to create an unrelated subreport in another unrelated report

Question

I have an unrelated XtraReport that has a subreport control that contains another report. I call it “unbound” in a report that has a field definition using a schema but is not tied to any DataSet, I create a DataTable using the data access level, and then pass that object to the DataSource property of the report.

So, I have the following code:

        // (...) Get the data from the db and fill a DataTable

        if (table.Rows.Count > 0)
        {
            report.DataSource = table;

            // (...) Get the data from the db and fill a DataTable for the subreport
            report.SubPurchaseOrder.Report.DataSource = tableSubReport;

            report.ShowPreviewDialog();
        }
        else
        {
            MessageBox.Show("No data to show.");
        }

But what I get when using this approach is a very detailed report, presented below (see attached pdf , sorry in Spanish, but I think you understand this idea).

- . BeforePrint subreport :

((XRSubreport)sender).ReportSource.FilterString = "[IdPO_RO] = " + _idPurchaseOrder;

((XRSubreport)sender).ReportSource.Parameters["Id"].Value = _idPurchaseOrder;
