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.

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).

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.

I am having an issue with the output file format on a production where quotes (" ") around column values are being removed from the imported file. For example, my input file is a csv formatted as such: "123", " ", "ABC". The output file format that is being generated produces: 123, , ABC. I need the output file to retain the quotes around the data.

Is this something that can be corrected in the record map? Or is it an issue elsewhere?

We have one user that is having issues in Ensemble via browser. The two issues she reported are:

- If she opens a DTL, she has to Save or Compile the DTL before she is able to edit anything in the Actions tab. Typically, you can simply open the DTL, click on a line, and edit the Actions.

- If she opens the Tools tab and clicks the Test button, she does not get a response and it eventually times out on her. Typically, clicking the Test button will open a new window where you can paste a message to test your DTL with.

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.

Two fairly common requests we receive from HL7 customers are (1) how to remove all trailing delimiters for fields and segments in HL7 messages and (2) how to "find and replace" for an entire HL7 message (as opposed to one segment/field at a time). The code sample below shows a custom function that solves for item 1 and by extension item 2 above. In other words the same approach can be used for finding/replacing any sequence of chars in an entire HL7 message, with some tweaks to the custom function.

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

I came across How to import a tab separated text file into a SQL table programmatically?, which appears to indicate that I can pass the filename and all records will be imported. However, when I put use the Import method only a single record gets imported. However, all records are imported if I use the management console to import the file by selecting it and choosing the options.

Has anyone ran into this in the past?

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.

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.

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

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")"

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

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

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.
