Странно! Каким способом ты получаешь данные из запроса.
Вот такой пример работает без проблем

Queryrun main_query(boolean _count_query = false)
{
    VendInvoiceJour     VendInvoiceJour;
    QueryRun            QueryRun;
    Query query   =      new Query();
    QueryBuildDataSource qbds;
    QueryBuildRange      qbr;
    ;
    qbds  = query.addDataSource(tablenum(VendInvoiceJour));
    qbds.addSortField(fieldnum(VendInvoiceJour,purchId));
    qbds.addSelectionField(fieldnum(VendInvoiceJour,Qty), SelectionField::Sum);
    qbds.orderMode(OrderMode::GroupBy);
    qbds  = qbds.addDataSource(tablenum(VendInvoiceTrans));
    qbds.addLink(fieldnum(VendInvoiceJour,purchId),fieldnum(VendInvoiceTrans,purchId));
    qbds.joinMode(JoinMode::InnerJoin);
    qbds = query.dataSourceTable(tableNum(VendInvoiceJour));

    QueryRun = new QueryRun(query);
    while (queryRun.next())
    {
        VendInvoiceJour = QueryRun.get(tablenum(VendInvoiceJour));
        info(strFmt("%1  %2",VendInvoiceJour.PurchId,VendInvoiceJour.Qty);
    }
}
