Hi Oliver,

I have tried the same steps by using BPL i am able to convert the message  but i am not supposed to use BPL logic in my tasks , so i am trying to figure other ways for this conversion 

Thank you ,

I have tried the steps mentioned in the below post but i am not sure what values i need to use in few variables


This is example mentioned in the link

SET tContent = %request.Content.Read()---->in %request do we need to declare any variable

WHILE '%request.Content.AtEnd {

SET tContent = tContent + %request.Content.Read()


SET tReq = {}.%FromJSON(tContent)

SET tInput = tReq.Message

// Remove your %New() statement and set tMsg like this

SET tMsg = ##class(EnsLib.HL7.Message).ImportFromString(tInput)

// Then you can either set the doctype manually or use PokeDocType()

Let me know  if you have any ideas on this one?


I agree with your point it will be very helpful to have basic examples for new developers in Cache Object scripts.

Can you please give me an example  how to create a JSON message structure @Phil Burkhalter  for a JSON message?



Thank you Robert, It worked.

Set Jsonobj="{""Doctype"":""ADT^A01"",""PatientId"":""123"",""PatientName"":""Alex""}"

set dynmicobj={}.%FromJSON(Jsonobj)

Set HL7Obj=##Class(EnsLib.HL7.Message).%New(dynmicobj)

---> here i am trying to open an Object trying to Convert JSON to HL7 message

Can you share any ideas how can i proceed from this steps to convert into HL7 message ?

Hi Robert 

I have tried by giving Set Dynjsonobj={}.%FromJSON(Jsonobj) it is throwing below error 

<THROW>%FromJSON+37^%Library.DynamicAbstractObject.1 *%Exception.General READ error while reading input stream 10 Line 1 Offset 0

Is there any way i can read from the JSON object

Thank you ,

Can i give the OnProcessInput method like below 

Method OnProcessInput(pInput As Ens.Request, Output pOutput As Ens.StreamContainer) As %Status

How to map the fields in JSON file to HL7 message Fields?

Thank you 

Can you please give me an example how can i save Non HL7 file data into SQL example any CSV file data into SQL Dynamically ?
