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?

Hi ,

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

Hi Team,

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.

Thanks,

Harshdeep Acharya

Hi ,

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

Comparisons in DTLs

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.

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

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?

Thanks

Scott

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.

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.

Hi, guys,

I've written a DT for a partner which transfers a csv file into SDA3.

I', using record map to gather data from a folder storing csv files and using the DT to tranfer the records into sda3 entities.

The followings are the codes of that DT:

Class POC.DT.CSV2SDA3 Extends Ens.DataTransformDTL [ DependsOn = (User.PhysicalExam.Record, POC.SDA.Container) ]

{

Parameter IGNOREMISSINGSOURCE = 1;

Parameter REPORTERRORS = 1;

Parameter TREATEMPTYREPEATINGFIELDASNULL = 0;

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:

How can I remove those trailing iterations?

Requirement: Transform source XML message to target JSON.

step1: First create json equivalent xml from any online tool.

step2: use add in studio utility create persistent classes from json equivalent xml and compile it , now target persistent classes are ready

step3: Do the above step for source xml or xsd and generate persistent classes for source and compile it

step4: complete the DTL by selecting root node from source, target persistent classes and complete the mappings and compile it

Hi Friends ,

We have requirement to convert source hl7 message to target json message using dtl.

Currently I have created persistent cls for json and completed the dtl.

DTL giving output as json equivalent xml.

Now how to convert DTL result xml object to json?

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?

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.
