Check this page from the documentation.

I think that already exists an open exchange project to convert hl7 to xml, check this:

Have you tried creating a class of type "view" joining both tables? Maybe with that class you can create your cube definition.

Here you can see and example of this type con classes.

I've no idea about how IRIS FHIR Server works with the profiling but according to FHIR documentation...Did you define in the meta element the profile property for the Patient resource? In theory you have to include that info to apply the profiling for the resource.

You can find here the description of profile property in FHIR documentation

It should be something like this:

<meta>
    <profile value= "http://localhost:52773/fhirr4/StructureDefinition"></profile>
</meta>

How are you importing the Python library in your class? Have you declared your method language as Python? Did you see the package installed in the path defined by the documentation?

If you are getting:

callresponse.%ClassName(): Ack

And your code is:

if (callresponse.%ClassName() = "consultarEstudiosDatosPacienteVNAResponse"){
	set callresponse = ..respuestaConsultaEstudios
	Quit $$$OK
}

It will never send back respuestaConsultaStudios because the previous condition, try assigning respuestaConsultaEstudios to callresponse without it.

Maybe you can do a workaround for this problem creating a new Business Process to send respuestaConsultaEstudios and manage it from there, ignoring from EnrutadorConsultarEstudiosVNAv01r00 the null response that you receive from ConsultarEstudiosMedianteFind

Another option could be define OnResponse method on ConsultarEstudiosMedianteFind and define the response properly.
 

Oh! forget what I said, I was thinking that you were calling a Business Operation all the time...remove the pOutput from the OnMessage method .

I see what is the problem. Your BP is using the method OnMessage to do the C-FIND operation, but the OnResponse method is not receiving the response.

Remove the pOutput references from your code and try with the following code:

do ..%responseSet(..respuestaConsultaEstudios)
Quit $$$OK

Not sure if that would work.

Did you update the call from EnrutadorConsultarEstudiosVNAv01r00 to ConsultarEstudiosMedianteFind  adding the variable by reference?

For the Quit you have to return the status, is not necessary to return the output variable. You have to update the call to Procesos.DICOM.ConsultarEstudiosMedianteFind adding the output variable as reference.

And the Quit is what is generating the null response. You have to avoid the async call and return the result using an output variable.

I suspect that the problem is that you are sending a SendRequestAsync to  EnrutadorConsultarEstudiosVNAv01r00 that is the business process that called to Procesos.DICOM.ConsultarEstudiosMedianteFind, and after that you are doing the Quit, returning to  EnrutadorConsultarEstudiosVNAv01r00 again.

Try adding a $$$TRACE in this method:

Method OnAssociationReleased(pSourceConfigName As %String, pInput As EnsLib.DICOM.Notify.Released) As %Status
{
    #dim tSC As %Status = $$$OK
        
        #; The association between this process and the operation has been released, so we are now
        #; not connected to the operation
        Set ..CurrentState="OperationNotConnected"
    
    ; Añadimos 11 10 2023
    
    
    Set tSC=..SendRequestAsync("EnrutadorConsultarEstudiosVNAv01r00",..respuestaConsultaEstudios,0)
    
    Quit tSC
}

Maybe you are calling the BP from here with a null response.

Hi Yone! You can follow step by step the following article to create a REST web service from scratch:

https://community.intersystems.com/post/creating-rest-service-iris

As you can see this web service is not a Business Service, it's a web application that invoke a Business Service, I suggest you to use that way.
