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 have a case where I need to look up the NPI provider against an External MS SQL database to retrieve our Provider Identifier to send to a downstream system. In the past I would use a Business Process (BPL) to connect to the outside MS SQL via JDBC and get that information for me. But I was thinking instead of creating a BPL process to do this, would it be better just to link to the outside MS SQL database table to retrieve the information in a SQL statement within a DTL?

Hello, our Team is trying to develop Ensemble DTL to transform incoming X12 files into persistent data records. We created a persistent class and we can insert data using SQL. We tried to verify that %Save() gets called by adding %AddToSaveSet() method to persistent class and there writing to a global. We had to extend our persistent class with Ens.VDoc.Interface class or we could not see %Save() being called from Ensemble DTL. We suspect that %Save() gets some kind of error. We tried to debug by overwriting Transform() method in our DTL class.

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.

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.*

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.

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!

I was looking for an easier way to build the FHIR Query String, given the Record Map request that is passed into the DTL.

I built this Function, but when I run a message through it, my Query String that is passed back into the DTL is a Reference Pointer and not the String I am looking for.

Hi,

Does anyone have a sample that demonstrates how to use the Data Transformation option create='existing', in order to update an existing object by its ID? My use-case is that I have an HL7 message coming in which contains data on a patient that may or may not already exist in a (non-HL7) table. I want to use the PatientID from the (source) HL7 message, check if that patient exists in the (target) object, and if so, insert some new data into the existing patient, or if not, create a new patient.

I need to add some extensions to the HS.FHIR.vSTU3,Model.Resource.Patient class and then use those extensions to convert incoming FHIR JSON to the FHIR Patient Resource and Likewise add functionality to create A FHIR Patient (target class) from my patient database into the FHIR Patient Resource Object (target class)

many months ago I found a tutorial that explained all of this but can no longer find that tutorial.

Yours

Ensemble 2015. Working on an a way to send NACK'd HL7 messages to a flat file for external review/troubleshooting. (Similar to the way BadMessageHandler deals with validation errors.)

I think I have the Alert piece down, but need assistance with the exact syntax to do an SQL query in the DTL (or a custom function) to pull the HL7 message Raw Content into the Alert, based on the SessionID.

(Also, anything special to write alerts to the File Operation?)

Thanks, Brian

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

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-obj...

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

Hi All

I have a BP which has a transformation.

when I run the process I end up with the following error:

----

ERROR <Ens>ErrBPTerminated: Terminating BP Propirion.BP.GetServices # due to error: ERROR <Ens>ErrGeneral: Object is immutable
+
ERROR <Ens>ErrGeneral: Object is immutable

----

I have created a context named : HL7Message type of: EnsLib.HL7.Message and in the start of the BP assigned the request to it (using set in assigned activity)

What did I miss ?

Thanks

I have an EMR sending double quotes "" as the value. How do I write criteria to find this match in a DTL?

PV1|1|A|||||1111111111^Doctor^MR|||||||||||||||||||||||||||||||||||||20170331|""

source.{PV1:DischargeDateTime()}="""" didn't work

Hi all,

I'm looking for a user-friendly way to make a method library available in DTL, and by user-friendly I mean via '..MyMethod()' or '$$$MyMacro()' rather than '##class(MyPackage.MyClassName).MyMethod()'.

Does anybody know of a way to add a second superclass or a set of macros to a DTL ... or some other trick?

Cheers,

Otto

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?

We are receiving an ORU message and the vendor is requesting that we append a new OBX segment at the end of the message and I wanted to reach out to see what options might be available.

So far, I tried the append action in the DTL editor with a single OBX-3 field but it seems to be appending to the field directly instead of creating a new OBX. I've started looking into if whether I could use a function but wanted to first check with the experts on the Discussion here in case there's an easier way to accomplish this. Thank you.

In specifying a "WHEN" condition statement, I don't seem to be able call a function directly from this declaration, as the generator seems to get confused

In the graphical editor:

%request.GetValue("MRN"))=123453

(%request.GetValue("MRN"))=123453)

In the DTL directly:

<when condition="(%request.GetValue(&quot;MRN&quot;))=123453)">

<when condition="(%request.GetValue&#40;&quot;MRN&quot;&#41;)=123453)">

DICOM to HL7

We have a case where a vendor can send us more information in the DICOM message rather than in the HL7 result message. In theory it should be possible to take a DICOM and convert it to HL7, stupid question is has anyone done it before? Does anyone have any good examples of a DTL they did to show me how to setup the message structures and translation?

Thanks
