С QueryRun точно работает. Вот джоб:

static void Job10(Args _args)
{
    InventTable     inventTable;
    Query           query = new Query();
    QueryRun        queryRun;
    QueryBuildDataSource    qbds;
    int                     i = 2;
    ;
    qbds = query.addDataSource(tableNum(InventTable));
    qbds.orderMode(OrderMode::GroupBy);
    qbds.addSortField(fieldId2ext(fieldNum(InventTable, Dimension), i));
    qbds.addSelectionField(fieldNum(InventTable, RecId), SelectionField::Count);
    queryRun = new QueryRun(query);
    while (queryRun.next())
    {
        inventTable = queryRun.getNo(1);
        info(strFmt("%1  %2", inventTable.Dimension[i], inventTable.RecId));
    }
}
