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.

Date Filtering Functionality

I have come across several cases where I need to set a Date filter to send only send any admit/scheduled date past a certain point. We have a couple different date comparison functions but none looking at the true date. Most of them are date + 15 or etc. Does anyone have a good date function they have written to say if x > 20170102 ?

Thanks

Hi,

Can anyone point me to an example of a DTL & Class method that can pull a base64 encoded PDF out of a MDMT02 message?

This is really asking for two things;

- how to make a DTL that extracts a specific subfield of an HL7 2.3 message into a message of its own,

and

- how to transform an base64 encoded document into its original binary form for writing to a file.

I'd also love to see an example of an HL7 2.n MDM^T02 ==> HL73.ITK2 non-coded CDA

There has been some confusion about how to edit Business Process Language (BPL) and Data Transformation Language (DTL) files in Atelier using the graphical editor. The following steps describe how to do this with Atelier version 1.0:

Copy the file you want to edit from the server to an Ensemble-enabled project in your Atelier workspace. To do this, find the file in the Server Explorer, right click and select Copy to project.

Open the file in the Atelier class editor just as you would any other class file.

I am trying to transform an Enlib.EDI.XML.Document through aXLT I know how to trans form the xml document through a xlt stylesheet but been trying to get an Enlib.EDI.XML. Document from a procees by creating aoperation that will do the transformation of this to file if this can be done in a process all ideas welcome so far I have come to this and I keep getting an error

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?

Looping through a DTL

I have a DTL that reads an xml file and I want transform that to a list of objects but I have a problem looping through my xml as when I try I get the first instance on the xml not the whole XML being transformed. here is my example. Here is the output

I have a batch record mapper that reads a csv file and passes the message to a process that uses the EnsLib.MsgRouter.RoutingEngine and would like to pass the message to an operation that will output that as a XML file but so far been unlucky as the operation that I use , uses the EnsLib.EDI.XML.Operation.FileOperation which only works with the messages("BusinessOperation class for writing XML messages to a file.

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

I've got a Service that get ACK Messages originated by another system.

I want to get the details of a Message when the ACK is CE (Failed Message).

I don't know whether this is the best approach but, at the moment, I have a DTL and I would like to search the Cache Database for a Message with the Control ID on the ACK in the MSA segment.

Any help with this would be great.

Tks.

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.

Suppose I have an image and need to convert that image into a PDF for inclusion in an HL7.

I know that Zen Reports can display an image in a PDF but I do not want to view the image in a web page. I just need to convert the image to PDF in a Process and then include that PDF in an HL7. The workflow would be like this:

Get image -> Convert image into PDF -> Include PDF in HL7 OBX.

I know how to do the last part to include PDF in HL7 OBX. Just need ideas on the first part.

Folks

1) What's the correct way to check for an existence of a segment? So far I have been doing this by checking to see if a required field is non-null, and this seems to work but is a bit clumsy. In this case, it’s an X12 message being checked in an IF action in BPL:

request.GetValueAt("NTE(1):Description")'=""

Or in a DTL, to see if a Z segment exists:

source.{ZEF:Counter}=1

With help from others here I had developed some code to take a Base64 PDF within a OBX.5 and save it locally to the file structure on the server.

I had to make a change to the code to return me a String so I can pass the Path back into Ensemble to use it in the message. When I made this change I am getting " ERROR #5034: Invalid status code structure ("/ensemble/data/transfer/AncillaryPDF/TMSAUDIO/Apr-11-1/980512729TMSAUDIO1046784936436537800.pdf")"

Here is the code...

I created a DTL to do HL7 mapping. The test function in the tools works the DTL perfectly but when used by the rule in my business process, the OBX segments are stripped and the MRN is gone. The assigning authority and ID type are added into the PID but the actual patient MRN is blank (3.1 value).

Here is the source code.

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.

Hi all,

We have a big problem with spanish accent and special characters using Data Transformation (HL7 Messages).

We have some DT to transform HL7 messages to other type (OUL^R22 To OML^O21) so it copys the PID segment to the new one, but if in the PatienName field has any special character, the transformation stops and it not continues with the transformation.

This is the message
