#DTL

Hi Everyone,
Please suggest/share best practices and sample questions that would help me to secure InterSystems HL7 specialist Certification.

We have a scenario where we use the best practice article of a BP and DTL to split up HL7 messages mainly ORUS 

https://community.intersystems.com/post/splitting-oru-messages-using-ob…

It is really useful but we have this code in many places that we are trying to consolidate it in one place. 

We do not want to split it at the first stage in our rules as there is a lot of messages that go to sink. So we are trying for specific rules and the incoming hl7 matches certain rules and classified for certain downstream systems that it is then split and transformed.

Hi Team,

I am converting xml message into HL7 message but the input XML message contains pdf which is converting into base 64 and getting mapped to OBX:5.5 in HL7 message and sending it to downstream 

In Downstream service i am using normal HL7 TCP class EnsLib.HL7.Service.TCPService but the message looks like below i am not sure why stream is taking as another segment in HL7 message,

Any thoughts on this?

Thanks,

Smythee

Folks,

I need help mapping following JSON elements with HS.SDA3 Container. Could you please share if you have any mapping details.
Source ------->Target (SDA3)
Medication (Custom Persistent class with HS.SDA3.Medication)
Procedure(Custom Persistent class with HS.SDA3.Procedure)
Referral (Custom Persistent class with HS.SDA3.Referral)
Appointment (Custom Persistent class with HS.SDA3.Appointment)
Immunization (Custom Persistent class with HS.SDA3.Vaccination)
Diagnosis (Custom Persistent class with HS.SDA3.

Can you assign the SessionId to a target field in a DTL. There is a %Ensemble("SessionId") variable that looks like it would be available to use.

Hello All

I'm not sure what the best practice is for this. I have a DTL for returning ORUs back to a hospital in a different time zone. They have requested that various timestamps have the time zone offset added to the HL7 format (%q%k, I think). First, I just wanted to be sure the system was aware it was DST. I was able to determine if DST is in effect like this:

<assign property='tzOffset' action='set' value='"-0500"' />
<code><![CDATA[ 
         SET dst=$SYSTEM.Util.IsDST()
         IF dst=1 {SET tzOffset = "-0400"}
         ]]>
    </code>
<assign property='target.

Hi Community,

What is Defination of XData which we use using in Object script 

we are using XData  MessageMap and  XData DTL 

How can we use XData for different functionalities 

Thanks,

Hi Community,

Is there a way to call HL7 Data transformation directly from Business service without using Rule functionality in the production

In this scenario i need to call a data transformation in directly in business service and give the transformed message to Business operation 

Please share if you have any ideas to implement this.

Thanks,
Smythee

Hoping someone can help,

I have the "Sample FHIR Production" installed ( as described in the documentation) with the following Components:

Service: HS.Gateway.ECR.SDA3XMLFileService

Processes: HS.FHIR.FromSDA.DTL.Transaction.Process

Operations: HS.FHIR.Repository.Operations

When a patient's data gets updated in my application a new SDA3 message is generated and processed by the FromSDA DTL. The Repository Stores that data as a New patient ( i.e. when I query the Repo they have different IDs "resource":{ "resourceType":"Patient", "id":"4", ) .

Hi all

I'm having trouble defining the mapping needed to take the very large base64 string in OBX:5.5, and map it to an XML virtual document property that supports Stream.GlobalCharacter. I know from within the DTL you have to use custom code to manage the segment due to its size. 

do target.StoreFieldStreamRaw(.stream,"LetterAttachment(1).Base64EncodedFile(1)", .rem)
 set tObx14Value = $piece(rem,"|",10)
 set convertedDate = ##class(Phu.Shared.Util.DateTime).ConvertHl7DateTimeToXmlDateTime(tObx14Value)
 do target.SetValueAt(convertedDate,"DocumentDetails(1).AuthoredDate(1)")
 do target.

Can someone share some details for creating a  pipeline for converting CCDA (XML) document into Flatfile or CSV File using IRIS.

Could you please help me out identifying the inbound and outbound adapters along with the DTL process for converting CCDA into CSV Files.

Thanks in  advance!!

I am receiving a FHIR bundle and I need to extract data from it and wondered if there was an easier way of doing this rather than looping through the data as suggested in Working with FHIR Data | FHIR Support in InterSystems Products | InterSystems IRIS for Health 2023.2.

Ideally it would be great if there was a DTL the accept STU3 and then extract the data from there and I did try using the HS.FHIR.DTL.vSTU3.Model.Resource.Bundle class (depreciated) but that only allowed me to see the data at the bundle level and not the resources within it (entry).

Hello,

I have a problem attempting to store a base 64 encode stream into the OBX:5 field of a HL7 message, by using the StoreFieldStreamBase64 method.

I'm using a transformer to input the contents of a pdf within a stream container (Ens.StreamContainer). The output is a HL7 message (EnsLib.HL7.Message 2.5:ORU_R01).

The transformer is being used in a business process.

This is the code used in the transformer to encode the stream to base 64:

Try {
     Set pdfStreamObj = source.StreamGet()
   } Catch {
      Quit
   }

 //Set PDF stream object into OBX:5
   Set status = target.

Hi Community,

I have SDA file as Ens.StreamContainer Message using pRequest As Ens.StreamContainer

SDA file structure looks like this 

<Name><FamilyName>Lucy</FamilyName><GivenName>Hale</GivenName><MiddleName>Park</MiddleName></Name><Gender><Code>F</Code><Description>F</Description></Gender><BirthTime>2023-09-07T00:00:00</BirthTime>

How can i change individual value from the Steam and then save changed value into the stream?

Way back when during our Siemens LCR days we had to limit the number of characters in OBX.5 to a length of 75. That was back when we had eGate.

Now I need to do the reversal of that and take loop through a string length and split the string up into multiple OBX or NTE based on a certain length. In reading documentation $EXTRACT can do this if you know the exact length, but in this case we don't. 

So how would one loop through a string and say every 75 characters create a new OBX or NTE segment?

Thanks

Hi,

Using Interoperability, I can't figure out how to create separate XML's files from a CSV-file using the GUI-features Record Maps/Complex Record Mapper -> Data Transformations. I'm familiar with reading/writing the files using File Service/Operation, but don't understand the processing-steps. The preferred method by my colleagues is to do this without any Objectscript or Embedded Python coding, but if this can only be done by some coding that's fine as well.

See example below. Any help is appreciated!

Looking to pull out HL7 Fields data to put into columns in a SQL table. How to handle the repeated fields & segments data  to SQL.

Appreciate your Help!!

Hi all,

I am looking for a way to serialize fhir content received via interoperability adapter into it´s corresponding ISC model class (e.g. HS.FHIR.DTL.vR4.Model.Resource.DiagnosticReport) for later use. In my opinion the outline to accomplish this would be something like

1) Receive the FHIR data
2) Get quick stream containing the JSON data
3) Examine if bundle or single ressource
4) For resource serialize to coressponding model class (HS.FHIR.DTL.vR4.Model.Resource.*)
5) further use of newly created object of type HS.FHIR.DTL.vR4.Model.Resource.*

Of course something like set tObj = {}.

Hi,

Is there a way to insert new Key/Value in an existing  lookup Table via a DTL code?  The only thing I found in the documentation is that we could use the following command SELECT KeyName,DataValue FROM Ens_Util.LookupTable WHERE TableName = 'myTab'. In the meantime I just created a table and  used it in my DTL to insert new values and validate if the Key exist.

Regards

Hi

Is there a way to read JSON and transform it (in DTL) by using a VDOC of this JSON (without transform it to internal message) like I can do with HL7 or XML?

If it possible, I guess that I should have a schema of the JSON so the second question is how to build a schema for JSON and load it to the IRIS?

Thanks, Ori.

Hi Team,

Can you please help me to develop EDI X12 to XML and XML to EDI X12 conversion in IRIS 2021.1 for EDI 204, also known as Motor Carrier Load Tender?

Also, suggest flow for how to achieve this kind of functionality in InterSystems IRIS. If you are able to provide some Videos/Documents on the EDI X12 interface for 204 then it would be very helpful for me.

Thanks,

Harshdeep Acharya

Hi ,

I am Converting HL7 message into SDA3 format by using  Ens.DataTransform Class but transformation is not happening while using this class and throwing the below error

ERROR <Ens>ErrException: <UNDEFINED>zTransform+1^Hosiptal.SDA3.DataTrans.1 *target -- logged as '-' number - @' Set target.Patient.Name=source.GetValueAt("PID:5")'

Let me know if any mistake please refer the below code

Class Hosiptal.SDA3.DataTrans Extends Ens.DataTransform
{

ClassMethod Transform(source As EnsLib.HL7.Message, target As HS.SDA3.Container) As %Status
{
 
   Set target.Patient.Name=source.

Hi all,

I'm trying to convert a HL7 section to a XML or JSON string.

We need to save the content of PID section into a SQL Column, therefore we need to convert it into a XML o JSON string

is there any easy way to convert it?

I've tried to convert it directly into a DTL, but all my attempts have been unsuccessful

Best regards,

Francisco Lopez

I noticed today that when we are creating a message from one doc type to another doc type, that the message type categories are not necessarily set. This is causing some issues with routing rules when we try to reference the Message Type Categories. Is there a way to make sure the Message Type Categories are being set within a DTL to make sure this doesn't cause problems down the road?

Thanks

Scott

Hi

I have an a Ens.Request subclass (Invoice) that has a relationship property to another persistent class (InvoiceItems), with properties of its own and the inverse relationship defined referring back to Invoice. 

When building a DTL with these classes, the Relationship’s inverse relationship (Invoice, within InvoiceDetails) is displayed.   

Can this be hidden ? 

thanks

Good afternoon,

I'm trying to take an unformatted social security number and insert the dashes into it.  I'm getting a value in PID-19 like this:  "123456789" and would like to use a data transformation to set the value in PID-19 to "123-45-6789". 

I can't find any insert or append functions and I can't find anything in the Intersystems doc repository that would do this.  Can someone help point the way for me please?  I would like to keep this as a "set" action in my DT.  I'm a little new to calling classes so it would be helpful if you included some syntax that would go in the "Value" field.

I need to split a large XMLfile  into multiple smaller ones, grouping by an element multiple iterations deep.

In XSLT 2 I use for-each-group  group-by,  which perfectly does the trick.

I wonder if it is possible to do the grouping  in DTL?

Hi, guys,

I've written a DT for a partner which transfers a csv file into SDA3. 

I', using record map to gather data from a folder storing csv files and using the DT to tranfer the records into sda3 entities.

The followings are the codes of that DT:

Class POC.DT.CSV2SDA3 Extends Ens.DataTransformDTL [ DependsOn = (User.PhysicalExam.Record, POC.SDA.Container) ]

{

Parameter IGNOREMISSINGSOURCE = 1;

Parameter REPORTERRORS = 1;

Parameter TREATEMPTYREPEATINGFIELDASNULL = 0;

XData DTL [ XMLNamespace = "http://www.intersystems.com/dtl" ]

{

I'm required to do a transformation around patient physical addresses.  If (for whatever reason) a patient has multiple addresses, I want to move the home address to the first iteration of PID:11 and remove all other iterations.  I've accomplished the first bit using DTL, but for patients who have multiple addresses they are left with empty trailing iterations.  Here is an example I mocked up:

How can I remove those trailing iterations?

This is part of the DTL I've written to do my transformation:

<foreach property='target.{PID:PatientAddress()}' key='i' >
<if condition='source.

Hi Community,

I have created persistent classes for source, target XSDs and completed DTL. When I tested in DTL window by passing source xml it is generating below target xml as result.
