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.

Consider the below scenario:

1. HL7 Service -> Process

2. DTL makes a call to a webservice (Post) via a REST operation via SendRequestSync call.

a. if the post is successful, end the DTL

b. if the server that hosts the webservice is down, i would like to keep retrying with the same message and not lose any messages in the queue.

does a simple "quit 0" at the DTL will rollback the message and will retry? please let me know how not to lose any messages if the webservice server is down.

Appreciate it.

Hi All,

I know hundreds of people have done this but I'm looking for some DTL's as a start to do HL7 to FHIR, I appreciate everyone's HL7 is slightly different, but just some starter DTL's would be much appreciated? Can anyone help?

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!

Hello Community,

I need advice converting a comma delimited string container with multiple records into some type of recordmap that iterates through all the records.

My string container has several records and I would like to loop through the number of records in the string container and transform each record in the container individually. Number of records will vary but the number of fields per record is static (28 fields). Meaning after every 28 fields, a new record begins. The goal is to convert to individual delimited flat file records.

Hi there,

I'm working on a project where I retrieve RawHL7 message(ORU R01 2.3.1) content from a database in a BPL. I've created a context object of type Enslib.HL7.Message, and I need to populate it with the contents from the RawHL7 message so that I can use this context object as source for my DTL transformation.

Does anyone have suggestions on the best approach to achieve this? I'm looking for guidance on how to efficiently transfer the data from the RawHL7 message to the context object.

Thanks in advance for your help!

Hello.

I have a delimited flat file that I need to read and then generate an HL7 A08 message from the fields in the file. I used the Management Portal's Record Mapper to generate the Map.Record class, then used drag & drop to map fields in the delimited flat-file to an A08 message.

But when I try testing this in the test tool, I'm getting an ERROR #6254: Tag expected . XML input. ... is not in proper format as child of Record (ending at line 2 character 11).

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:

I am working on tweaking our current patient load process. The roster input is in text pipe delimited format, parsed out and transforms it to a standard HS.Message.PatientSearchRequest, and send to business process for patient matching. Result is transformed into a standard ADT HL7 message using EnsLib.HL.Message class. I would like to know if there is another class I can use that will transform my output to a text flat file pipe delimited instead of HL7 format? any advice on how to do this is greatly appreciated.

Thanks!

I'm testing an HL7 2.4 -> HL7 2.3.1 set of transformations. For the time being the source (service) and sink (operation) are file adapters. What I'd really like is to be able to save the output file with a name matching/containing the input file name - but as the DTL transformation in between uses "new" rather than "copy" it looks like I'm losing (some of?) the metadata, including the "Source" field (Body tab, message viewer).

Is there any way of preserving the Source field so the OutboundAdapter has access to it?

Complex Record Map non-batch?

I would need to build a Complex Record Map and then transform that into xml. But not the whole batch to one xml file - instead every repetition in that Complex Record Map would become one xml file.

For Simple Record Maps this is easy to do because there are different types of Business Services that handle every record either individually or all of them as one batch but there doesn't seem to be similar options for Complex Record Maps? Instead, there is only batchtype business services.

suppressing a patient identifier

Hi all

Another newbie question.

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.
