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'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?
In terms of general through-put design and long term support, I'm considering what would be a "best approach" for needing to create multiple batch files in a few different layouts from the same data-sets.
Still a newbie for ensemble, I am trying to convert XML message to HL7 Message. I am using Custom schema for XML structure which includes MSH and PID segments from HL7 Message.
These are the service, process, Operation classes i am using
Business service-EnsLib.EDI.XML.Service.FileService
Business Process-EnsLib.MsgRouter.RoutingEngine
Business operation -EnsLib.HL7.Operation.FileOperation
Add a for each loop. Create and use utility functions. Create and use lookup tables. Use counting. Create and implement a subtransformation. Add a code action. Add a group of actions to organize relevant actions.
Can you please help me to develop EDI X12 to XML and XML to EDI X12 conversion in IRIS 2021.1 for EDI 204, also known as Motor Carrier Load Tender?
Also, suggest flow for how to achieve this kind of functionality in InterSystems IRIS. If you are able to provide some Videos/Documents on the EDI X12 interface for 204 then it would be very helpful for me.

I am Converting HL7 message into SDA3 format by using Ens.DataTransform Class but transformation is not happening while using this class and throwing the below error
ERROR <Ens>ErrException: <UNDEFINED>zTransform+1^Hosiptal.SDA3.DataTrans.1 *target -- logged as '-' number - @' Set target.Patient.Name=source.GetValueAt("PID:5")'
Let me know if any mistake please refer the below code
Is there a way to compare the value in a source field against all of the values in a repeating field? For example, we have multiple DG1 target segments populated. Is there an easy way to check a source DG1 segments against all of the target DG1 segments? I didn't know if there is a wild card I can use for the comparison.
I have an existing DTL and I need to insert a trace statement so that it writes the value of the target object. However, I haven't been successful in completing this.
I have opened the DTL viewer in Studio, and have inserted a trace statement.
I have a transform that I am calling from within an objectscript process, and I need to pass it a few values. I have in the past done this using the aux property, however I have got away with only needing to pass in a single value, so I have not had to worry about passing in anything other than a string container.
I noticed today that when we are creating a message from one doc type to another doc type, that the message type categories are not necessarily set. This is causing some issues with routing rules when we try to reference the Message Type Categories. Is there a way to make sure the Message Type Categories are being set within a DTL to make sure this doesn't cause problems down the road?
Hi, I am glad to announce another submission to OpenExchange and the current contest, the FHIR Pseudonymization Proxy. The FHIR Pseudonymization Proxy adds a transparent pseudonymization layer to any existing FHIR server, enabling clients to perform queries on the FHIR server – which may contain personal identifying information – and receive an on-the-fly pseudonymized version of the data.
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'm trying to take an unformatted social security number and insert the dashes into it. I'm getting a value in PID-19 like this: "123456789" and would like to use a data transformation to set the value in PID-19 to "123-45-6789".
I'm required to do a transformation around patient physical addresses. If (for whatever reason) a patient has multiple addresses, I want to move the home address to the first iteration of PID:11 and remove all other iterations. I've accomplished the first bit using DTL, but for patients who have multiple addresses they are left with empty trailing iterations. Here is an example I mocked up:
I have created persistent classes for source, target XSDs and completed DTL. When I tested in DTL window by passing source xml it is generating below target xml as result.
Problem to Solve: When an HL7 message hits a particular Process, I need to use the placer order number therein to query the messages that came in over the last 24 hours on a particular Service and grab discrete pieces of data that came in the latest message that has that placer order number.
We have a couple of systems that send us a URL link to a PDF instead of base 64 encoding it in the HL7 message. Has anyone ever tired to take that URL, and retrieve the file off of the server to save it off somewhere?
DTL Transformations and GetValueAt/SetValueAt calls on HL7 messages will truncate any fields longer than 32K. To avoid this, the methods GetFieldStreamRaw and StoreFieldStreamRaw must be used when dealing with fields that might be larger than 32K. OBX:5 is a frequent example. These methods have some subtleties and must be used carefully.
This can't be done by simply dragging from left to right in a DTL. It must be done with a code action. Also, the StoreFieldStreamRaw call must be the last edit made to the segment because the segment becomes immutable after that.
We are seeing ERROR #5002: Cache error: <MAXSTRING>zSaveData+14 ^EnsLib.HL7.Segment.1 come up on a Routing rule when we are trying to Encoded PDF's through a DTL. In the DTL we are copying source to target. Is there a limitation on trying to copy source to target?
At the bottom of the DTL you are see that we commented out converting the Encoded PDF to a Stream, is it recommended that we always use %Stream anytime we are dealing with PDF's?
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.
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
