Query Join AX 2012 Version 2

public void executeQuery()
{
  QueryBuildDataSource   cpj;
  QueryBuildDataSource   bol;
  query    query;
  query = CustPackingSlipJour_ds.query();
  cpj = query.dataSourceTable(tableNum(CustPackingSlipJour));
  bol  = cpj.addDataSource(tableNum(WMSBillOfLadingOrder));
  bol.joinMoIde(JoinMode::ExistsJoin);
  bol.fetchMode(QueryFetchMode::One2One);
  bol.relations(false);
  bol.addLink(fieldNum(CustPackingSlipJour, SalesId), fieldNum(WMSBillOfLading, InventTransRefId));
  super();
}
I tried the same in a job and it worked:
static void Job21(Args _args)
{
   Query       query;
   QueryRun    queryrun;
   QueryBuildDataSource    cpj;
   QueryBuildDataSource    bol;
   QueryBuildRange         qbr1;  
   CustPackingSlipJour     custPackingslipJour;
   WMSBillOfLadingOrder wmsBillOfLadingOrder;
   ;
   query = new query();
   cpj   =   query.addDataSource(tablenum(CustPackingSlipJour));
   qbr1  = cpj.addRange(fieldnum(CustPackingSlipJour,orderAccount));
   qbr1.value(queryvalue('CUST001'));
   bol   = cpj.addDataSource(tablenum(WMSBillOfLadingOrder));
   bol.relations(false);
   bol.joinMode(joinmode::InnerJoin);
   bol.addLink(fieldnum(CustPackingSlipJour,SalesId),fieldnum(WMSBillOfLadingOrder,InventTransRefId));
   queryrun  = new queryrun(query);
   while(queryrun.next())
   {
   custPackingslipJour   = queryrun.get(tablenum(CustPackingSlipJour));
   wmsBillOfLadingOrder = queryrun.get(tablenum(WMSBillOfLadingOrder));
   info(strfmt("%1 - %2",custPackingslipJour.salesid, wmsBillOfLadingOrder.billOfLadingId));
   }  
}
