Ensemble supports Data Transformation Language (DTL) for describing data transformations. DTL is an XML language. Ensemble provides wizards and graphical tools for creating, editing, and testing DTL transformations. A data transformation is a Caché class like the following. If you prefer you can use Studio to edit the class definition directly and bypass the wizards and graphical tools.

Documentation.

I need to set and use some context variables in a transformation (written in DTL), but the code is manually written.

When writing the same as BPL I define context variables and they are visible in transformations called by that process.

In something like this my.DTLtransform sets HL7 message fields to values in context variables:

DTL vs. ObjectScript

As I've become a little more familiar with HealthShare, I'd like to start exploring different ways of doing things. To date, the bulk of my data transformations have been using DTL; only using ObjectScript for a few operations that write to external SQL tables that were largely based on examples provided by my sales engineer.

Mass Export DTL

Hi Everyone,

We are trying to migrate old server to new infrastructure and need to sync all the DTL cls from old one to new one. There are hundreds of DTL in system and we tried to export from production but cannot select all at once which might cause some missing classes. Not able to connect to studio or atelier with that server neither. Is there any way that we are able to do mass export from system which will save some effort? Please let me know your thoughts. Thanks.

Hello, In the DTL, is there a way to set a value for the HL7 data element in the code section? For example, set target.SetValueAt("PID:3(k1).1)") = mrn (mrn is the value returned from the SQL query) When I ran the test utility, I got this error message. ERROR ErrException: zTransform+27^testclass.TEST.1 *SetValueAt,EnsLib.HL7.Message -- logged as '-' number - @' set target.SetValueAt("PID:3(k1).1)") = mrn' I tried both target.SetValueAt("PID:3(k1).1)") and target.GetValueAt("PID:3(k1).1)"). That didn’t make a difference. The code still error out.

- Currently we are receiving one NTE (See Below) from the source system

NTE|1|Result Comment|TESTING:\.br\\.br\This is a test results. \.br\\.br\This test is a Test.

- We would like to create multiple NTE segments and send to destination system by using ".\br\"(Line Break)

NTE|1||TESTING:

NTE|2||

NTE|3||This is a test results.

NTE|4||

NTE|5||This test is a Test.

We have a data transformation where source is object collection (populated from a json file) and target is EnsLib.EDI.XML.Document.

If source file is large enough, transformation fails and we get <store> error and I quickly found this:

https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=EBPLR_DTL_foreach which at the bottom in "Avoiding <STORE> Errors with Large Messages" section tells to:

In my Data Transformation, the Target class needs to create a new List of objects (ListOfObj), depending on some conditions of Source class (Source/Target are completely distinct/different classes).

I experimented with Lists of 'primitive' data types (ListOfDT), and I could add new %String items (as an example) to a List of %String property, with "append" action in DT.

Does anyone have an example, or guidance, how to create new Lists of Objects in data transformation?

For example, if I have a 'container' class like this, it works:

I'm not sure what the purpose of this is, but the Management Console causes the browser to refresh periodically. If you're in a form or an editor such as the DTL or Routing Rule editors, you may lose work unless you save frequently. This did not occur in Caché 2018 and earlier releases.

I've had a couple of incidents where I've created a number of rules in the DTL editor, answered the phone or stepped away for a few minutes, then come back to find any work since the last save erased.

I've noticed this in both 2019 and 2020 releases of IRIS.

Heads up!

Hi everyone,

I am very pleased to announce that the Readmission Demo has been released as open source. Many thanks to the Solution Factory team that worked hard on making this possible.

Here are the changes:

I have to write a DTL with the Data Transformation Builder to convert messages from HL7 ORU R01 v2.1 to HL7 ORU R01 v2.5. The incoming messages contain a text in OBX-5. This text contains LF characters (only LF - Segment separator is CR). Therefore it is not possible to parse the incoming message. While testing the transformation the OBX Segment ends at the first occurence of LF. Is there a way to replace the LF character before parsing?

example:

source:

OBX||FT|ltest1|| first line

second line

…

last line

||||||F|

target:

IRIS GUI/DTL Rewrite

Hi,

I've heard from two different sources the SMP (or parts of it) and for sure the DTL front end (in studio? via SMP?) have been rewritten to be more modern. But on a latest IRIS Community download everything looks the same to me. Am I missing something or is this Marketting Spin?

Hopefully I won't get banned for this post aswell......

Hi,

I am trying to add an OR condition in the DTL but not able to. Sorry if this is a silly question, but can you advice?

I want to add a condition where if source.45 is "" or "..." then map "" to the target. But I am not able to add the OR condition

Currently I have as below

What will I need to do to add an "OR" condition to the DTL?

Would appreciate your guidance

Regards,

ED

I must be missing something. We have done encoded PDF's in the past with the Encoded PDF in OBX.5.5. When I have used this code in the past I was only working with 1 OBX, but I have a case where I am having multiple OBX's and having to loop through them and I am renumbering the outbound OBX.

Unit Tests for Data Transforms

Would you like to be sure your data transforms work as expected with a single command? And what about writing unit tests for your data transforms in a quick and simple way?

When talking about interoperability, there are usually a lot of data transforms involved. Those data transforms are used to convert data between different systems or applications in your code, so they are running a very important job.

Hi Community,

I am trying to remove a duplicate OBX from a result, but I am running into some issues. Let me explain.

First I had a OBX where the observation Value had the blood type in it and the following OBX had the result in it.

The clients wants the blood type and the result in one field. therefore I merged / concatenated the observation values of the two OBX's.

I tried removing the OBX:2 but just cant take the whole segment out.

please see examples below

This is the result.

x12 substring manipulation

How do I manipulate a string in Ensemble DTL (X12 document) to extract a string starting from the right, or end, of the string?

I need to have 10 digit phone numbers, however some of the source data records include the "1" for the long distance dialing and I need to exclude this.

I have tried using Right(), SubStr(), and even SubString(string,*,-10) but it will not compile.

I find it hard to believe that Ensemble does not have the ability to read a string from the right.

Thank you for any assistance.

Hello All.

In need of some help.

We are currently migrating Interfaces from JCAPS to HealthConnect 19.1 and have done a lot of work on our Dev server. I am looking to copy/export this work over to the Test server and have managed to export the production and Rules, HL7 custom Schemas etc. The only thing left now are the Data Transformations but so far I can only find ways of copying the transformations over individually. Is there some way to copy all of the transformations we have produced in our namespace to another server in one go?

Thanks

Hello,

I have a DTL to transform X12 Document 278 Request to 278 Response HIPAA 5010 schema. The DTL is called from BPL. I defined a class method that receives source, target, and context objects. How can I create 2000F loops in the response when there were none in the source object?

Hello,

When creating an outbound X12 file (834, 835, 837, etc), what's the easiest way to keep a segment count to use in the SE01 element? Other mapping tools I've used either detect it's an X12 file and do this automatically, or there's an option to keep a count after each outputted segment. The Data Transformation tool within Health Connect doesn't seem to have similar functionality, but I could just be missing something. Any help would be greatly appreciated!

Thanks,

Jason
