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.

I am receiving a FHIR response bundle back with a resource of patient. Using fromDao, I attempted to take the stream and put it into FHIRModel.R4.Patient but it is not mapping correctly. When I attempt to take FHIRModel.R4.Patient and write it out using toString(), all I am seeing is the resource

{"resourceType":"Patient"}

so the response is not mapping correctly to FHIRModel.R4.Patient. How have others handled this? Do I need to translate it to an SDA since it does fit the model format?

We are receiving the report in text format and it has special characters like ', - like that in the text. Source system is using the UTF8 encoding format hence the text is showing as ' � ' . Is there a way to convert the utf8 to actual character in the DTL.

Thank you,

HL7 Section to JSON

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

So this may sound trivial, but I'm seeing conflicting information on this topic and hoping to get clarification.

According to Enslib.HL7.Message class definition, the maxlength of RawContent is 10,000 characters. So when using encoding like UTF-8, that is 10KB. When using Unicode, that should then be 20KB.

But then also coming across some forums and documents where 32KB is maximum size before HL7 fields are truncated.

What is the sure way to determine and modify an interface's maximum supported message size?

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

suppressing a patient identifier

Hi all

Another newbie question.

A small percentage of our patients have an extra hospital number which was imported from the previous PAS but is no longer in use. We only need to send MRN and NHS number and would like to suppress CMRN. Could you please advise me how to do it in DTL?

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

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:

I have a business service that brings in a xml virtual document to the production and also a csv service that brings in a csv file and have a process that transforms both to a xml output but I have a problem with the csv as it is giving me this error when I try to trans form it ```ERROR <Ens>ErrException: <PROPERTY DOES NOT EXIST>zOnRequest+1 ^EnsLib.MsgRouter.VDocRoutingEngine.1 *DocType``` I have read here followed the suggestion but now I do not get any errors but my m

Hi,

I have a PV1 repeating field that can contain multiple or a single value. I'd like to always pull the last value in the field but am not sure how to configure this in my DTL.

The repeating field is in PV1:50().1

Could somebody shed some light on this?

Examples:

|15081942~15081951~15108961~15280550|

|15081947|

|15081939~15081940|

Thanks

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.

I am working on creating a DTL that can replace OBX segment with a string formatted NTE segment . There is a class ImportFromString but it looks like that is not replacing the target message with the new formatted NTE. I do see target.setvalueat class but I wanted the transformer to not be scheme base.

Has anybody encountered this before?

I did a very usual hl7 adt transformation DTL, but it is with a customized schema, like ADT_ALL, it is a structure that tries to cover all the ADT schema scenario so we can use 1 type for all ADT messages.

the DTL tests fine in DTL test, with all the segment transformed correctly, but once I put it to test, to send message through source and the message after transformation can only go to MSH, EVN, but won't transform other segment like PID etc.

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,

is it possible to kill/suppress hl7 message in the DTL (data transformation).

in cloverleaf, it is common practice to check the value in message, for example pv1:7.9. if the value is certain word(assigning authority) then send the message over to destination, if it is not, kill the message

how would this be done in InterSystems ? does that need to be done in the rule instead? or can it be done in the data transformation? if it can be done in data transformation, how can it be done?

Thanks

I have an incoming data partner who occasionally passes a non-ASCII character in some free text fields which is causing some downstream systems to be unable to accept the message. Ideally I'm looking for some way to just process the entire message as a data transformation applied in the business rule, as we already have a pre-processor transform to remove the PD1 segment.

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.
