Hello @water huang 

As You can create a class method with name of your property " OPDTLogicalToXSD" and add the code conversion for the datetime as mentioned by @Enrico Parisi at XML export time.

It's suitable for both XML and JSON adaptor.

Sample code.

Class Samples.NewClass2 Extends (%Persistent, %Populate, %JSON.Adaptor, %XML.Adaptor)
Property OPDT As %Library.DateTime;

ClassMethod OPDTLogicalToXSD(%val As %TimeStamp) As %String [ ServerOnly = 1 ]
	Set %val=##class(%Library.TimeStamp).LogicalToXSD(%val)
	Quit $translate(%val,"TZ"," ")


 <NewClass2><OPDT>2023-11-30 11:07:02</OPDT></NewClass2>

Hello @Michael Wood

It won't allow to import the array values directly from the response/payload If you're using %JSONImport  in %JSON.Adaptor due to the datatype validation while import. So, You may define the list of properties in separate class definition and use that Property Messages As list of class if the array has object values and It allows to import. Or if it's literal string inside an array then it allows without any issues. 

Sample: Literal string values inside array

Class Samples.NewClass2 Extends (%Persistent, %Populate, %JSON.Adaptor)

Property email As list Of %String;


Property FirstName As %String;

Property LastName As %String;

ClassMethod test()
    set json={"FirstName":"test","LastName":"lastname","email":["test@gmail.com","test2@gmail.com"]}
    set obj= ..%New()
    set st= obj.%JSONImport(json)
    if $$$ISERR(st) write $SYSTEM.OBJ.DisplayError(st)
    write obj.%JSONExport()

Hello @Nimisha Joseph 
As per you're SQL implementation. It's actually straightforward and you took and store "Forename" and "Surname" in to context.  haven't taken any SQL resultset object to loop. You can execute only embedded sql in the <sql> BPL element.

So, If you want to execute the query you can assign the SQL object by using <assign> or you can use code block to write executable codes. I have added some sample code below for reference.

  • Assign the SQL result set object to context variable
  • while the result set
    • process and result and do your implementation
/// BPL Definition
XData BPL [ XMLNamespace = "http://www.intersystems.com/bpl" ]
<process language='objectscript' request='Ens.Request' response='Ens.Response' height='2000' width='2000' >
<property name='Forename' type='%String' instantiate='0' >
<parameter name='MAXLEN'  value='50' />
<property name='Surname' type='%String' instantiate='0' >
<parameter name='MAXLEN'  value='50' />
<property name='ReportDiscipline' type='%String' instantiate='0' >
<parameter name='MAXLEN'  value='50' />
<property name='tResult' type='%SQL.StatementResult' instantiate='0' />
<sequence xend='200' yend='950' >
<trace name='TEMP trace element' value='"In business process "_request.StringValue' xpos='200' ypos='250' />
<assign property="context.ReportDiscipline" value="request.StringValue" action="set" xpos='200' ypos='350' />
<trace value='"ReportDiscipline value: "_context.ReportDiscipline' xpos='200' ypos='450' />
<assign property="context.tResult" value="##Class(%SQL.Statement).%ExecDirect(,&quot;select * from table&quot;)" action="set" xpos='200' ypos='550' />

Hello @Colin Brough 

Can you try is this approach is suitable. Create a Business Service with Ens.InboundAdapter or without adapter. Call your BPL process as usual interoperability production flow.  Eventually Create your custom Task and invoke your Business service from the OnTask Inherited Method

Class HL7Task.Test Extends %SYS.Task.Definition
Method OnTask() As %Status
    Set status =  $$$OK
    Try {
        #dim service As Ens.BusinessService 
        Set status = ##class(Ens.Director).CreateBusinessService("HL7.Feed.TriggerService",.service)
        if $isobject(service) {
            do service.OnProcessInput(pInput,.pOutpt)
    Catch(ex) {
        Set status = ex.AsStatus()
    return status

Business service

Class HL7.Feed.TriggerService Extends Ens.BusinessService

Parameter ADAPTER = "Ens.InboundAdapter";
Property TargetConfigName As Ens.DataType.ConfigName;
Parameter SETTINGS = "TargetConfigName:Basic";
Method OnProcessInput(pInput As %RegisteredObject, Output pOutput As %RegisteredObject) As %Status
	Do ..SendRequestSync(..TargetConfigName,pInput,.pOutput)
	Quit $$$OK


Hello @Luis Angel Pérez Ramos 

as of my understanding, We can send the it's as a query parameter or http request body if the design supports. Incase the external system protocol was designed to handled the authorization and some additional custom headers are must be a request header Then it should be part of the headers section otherwise I believe it may creates some issue with the request/response.


Get/Post/Put any method will return status if error while executing otherwise return 1. The HttpResponse object property actually contains the response details such as status code, content length, content type, response etc... 

So, As you mentioned the code is "http.HttpResponse.StatusCode" is used to get the status code of the response.

  1. Basically you should keepIntegrity enabled. Otherwise it will delete all the messages regardless of whether processed or not processed.
  2. Select "All types" in Type to purge.
  3. You can enable the " Open output file when task is running? " and provide the file location.
  4. Once the process is completed or Errored you can check the Ens_Util.Log to get some additional information.

Can you try the above steps.
