Generating the outbound xml file for all records using File system adapater in ax 2012 AIF

1. Generating the outbound xml file for selected record or single record - using document service(file system adapter).

2. Generating the outbound xml file for all records( i.e. specified criteria on the query) - using document service(file system adapter).

Example: Generating the outbound xml file for selected record or single record.
Below is the code to generate the outbound xml file for the selected record.
static void GenerateXmlSelectedRecord(Args _args)
{
    AxdSendContext      axdSendContext  = AxdSendContext::construct();
    AifEntityKey        aifEntityKey    = AifEntityKey::construct();
    AifEntityKeyList    aifEntityKeyList = AifEntityKeyList::construct();
    Map                 keyData;
    AifConstraintList   aifConstraintList   = new AifConstraintList();
    AifConstraint       aifConstraint       = new AifConstraint();
    CustTable           custTable;
    int i,j;
    CustCustomerService CustCustomerService = CustCustomerService::construct();
    ;
    custTable = CustTable::find('Cust001');

    keyData = SysDictTable::getKeyData(custTable);
    aifEntityKey.parmTableId(custTable.TableId);
    aifEntityKey.parmRecId(custTable.RecId);
    aifEntityKey.parmKeyDataMap(keyData);

    aifEntityKeyList.addEntityKey(aifEntityKey);


    axdSendContext.parmXMLDocPurpose(XMLDocPurpose::Original);
    axdSendContext.parmSecurity(false);


    aifConstraint.parmType(AifConstraintType::NoConstraint) ;
    aifConstraintList.addConstraint(aifConstraint) ;

    info(strFmt("%1",custTable.AccountNum));
    AifSendService::SubmitDefault(  classnum(CustCustomerService),
                                aifEntityKey,
                                aifConstraintList,
                                AifSendMode::Async,
                                axdSendContext.pack());
}

Example: Generating the outbound xml file for all records( i.e. specified criteria on the query).
Below is the code to generate the outbound xml for all the records or specified criteria.

static void GenerateMutiplerecords(Args _args)
{
    CustTable           custTable;
    AxdSendContext      axdSendContext      = AxdSendContext::construct();
    AifEntityKey        aifEntityKey        = AifEntityKey::construct();
    AifConstraintList   aifConstraintList   = new AifConstraintList();
    AifConstraint       aifConstraint       = new AifConstraint();
    AifEndpointList     endpointList;
    AifActionId         actionId;
    Query               query;
    QueryBuildDataSource    qbds;

    query               = new Query(queryStr(AxdCustomer));
    AxdSend::removeChildDs(query);

    actionId            = AifSendService::getDefaultSendAction(classnum(CustCustomerService), AifSendActionType::SendByQuery);
    aifConstraint.parmType(AifConstraintType::NoConstraint);
    aifConstraintList.addConstraint(aifConstraint) ;
    endpointList        = AifSendService::getEligibleEndpoints(actionId, aifConstraintList);

    AifSendService::SubmitFromQuery(actionId,endpointList,query,AifSendMode::Async);
}
