может быть как то так:

static void Job2(Args _args)
{
    Query                   query;
    QueryRun                queryRun;
    QueryBuildDataSource    qbdsSalesTable;
    QueryBuildDataSource    qbdsCustTable;
    QueryBuildDataSource    qbdsSalesLine;

    QueryBuildRange           queryBuildRange;
    QueryBuildLink            queryBuildLink, queryBuildLink1;
    salestable  salestable;
    ;


    query = new Query();

    qbdsSalesTable = query.addDataSource(tablenum(SalesTable));

    queryBuildRange = qbdsSalesTable.addRange(fieldnum(SalesTable, SalesStatus));
    queryBuildRange.value( queryvalue(salesstatus::Backorder) );

    qbdsCustTable =  qbdsSalesTable.addDataSource(tablenum(CustTable));
    qbdsSalesLine =  qbdsSalesTable.addDataSource(tablenum(SalesLine));

    //qbdsCustTable.joinMode( 2 );
    //qbdsSalesLine.joinMode( 2 );
    
    qbdsSalesLine.fetchMode( QueryFetchMode::One2One );
    qbdsCustTable.fetchMode( QueryFetchMode::One2One );


    queryBuildLink = qbdsSalesLine.addLink(fieldnum(SalesTable, salesid),fieldnum(salesline, salesid));
    queryBuildLink1 = qbdsCustTable.addLink(fieldnum(SalesTable, custaccount),fieldnum(custtable, accountnum));

    queryRun = new QueryRun(query);


    while (queryRun.next())
    {
        salestable = queryRun.get(tablenum(Salestable));
        
        info (strfmt("salesid %1 - %2", salestable.salesid, salestable.RecId));
    }

}
