Как можно использовать join Query как DataSource для формы ?

[AndrianG]

Нашел решение, в init для DataSource пишем код:

public void init()
{
    Query query = new Query();
    QueryBuildDataSource wmsOrderTransQBDS, salesTableQBDS;
    QueryRun queryRun;
    QueryBuildRange qbr;
    ;
    wmsOrderTransQBDS = query.addDataSource(tableNum(WMSOrderTrans));
    salesTableQBDS = wmsOrderTransQBDS.addDataSource(tableNum(SalesTable));
    salesTableQBDS.addRange(fieldnum(SalesTable, asu_SOType)).value(enum2str(asu_SOType::AccessoryOnly));
    salesTableQBDS.addLink(fieldNum(WMSOrderTrans, inventTransRefId), fieldNum(SalesTable, SalesId));
    salesTableQBDS.fetchMode(QueryFetchMode::One2One);
    wmsOrderTrans_ds.query(query);
    super();

}

Спасибо за совет
