Greetings.

I have a scenario in ENSEMBLE, where a business process router A is dependent on another business process router B. If B shuts down for some reason, A has to be disabled as well.

Do i need to write a custom process for B and call the call back method onShutdown or something?

Any suggestions would be appreciated.

Thanks,

Jimmy Christian.

Rule logic

In an HL7 Business rule I am trying to block ONLY ORM messages that have a PV1:3.4 of 105 or 205 and a OBR:4 value of EP22 or CATH01.

I created the logic below but it appears to be evaluating the two fields independently instead of combined?

Here is what I had.

I have been successfully able to transform hand-written medical test results documents to HL7 ORU_R01 v2.x, then to SDA, which will be trasformed to FHIR or C-CDA.

However, I have a category of documents which contains reference range in multiple date formats, which are measured for each gestation period.
For example, below is one of the documents.

Analyte: HCG, Value: 1968, Unit: mlU/mL

HL7 test message generator

I am looking for an appropriate solution to generate HL7 test messages to test my production. IRIS for Health already contains many HL7 specific functions like the schema structures. Furthermore one can use transformations to build custom messages.

What I am interested in is if anyone has already created a tool or script that can be used to create any HL7 messages that meet the minimum requirements and populate all the required fields with test values. I would then like to send these test messages via TCP to a business service.

How to import Custom Schemas from VSCode? They look like this:

<?xml version="1.0"?>
<Category name="ITK" description="xmlns:hl7='urn:hl7-org:v2xml' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'" std="1">
<MessageType name='ACK' structure='ACK' returntype='ACK' description='xsi:schemaLocation="urn:hl7-org:v2xml ACK.xsd"'/>
</Category>

Instead of wrapped XML export produced by $system.OBJ:

Hi all,

I'm wondering if is possible to call to a BO from a HL7 Route according to a parameter of the HL7 Message

I mean,

According to the identify of the laboratory, I want to call to other TCP process to retrieve information about blood tests.

We are creating the BO using this partern.

LAB.BO.TCP. + name of the laboratory.

The name of the laboratory is stoted in the lookup table T_LABORATORIOS

I've tried to assign the name into a variable and put it in the "send" instruction, but it doesn't work.

Curious if anyone has modified the HL7 TCP/IP Service and adapter class to receive an HL7 message, ACK it, and just dump it straight to a file? I don't want the messages in the engine at all - just receive and dump. Has anyone done this before and have code you're willing to share?

Thank you very much in advance!

Hi,

we get HL7 MDM messages with embedded PDF documents that are Base64 encoded. When the embedded PDF document exceeds the size of 3.6 MB the following error occurs:

FEHLER <Ens>ErrBPTerminated: BP Main HL7 MDM # wird wegen folgenden Fehlers beendet: FEHLER #5002: Caché-Fehler: <MAXSTRING>zgetAtFromArray+46^EnsLib.HL7.Segment.1

Hello, I want to show a fellow DC member how to convert JSON file into HL7 message. I personally do not work with HL7. I set up a production with EnsLib.File.PassthroughService. It passes Ens.StreamContainer to BPL process. I call a DTL to transform StreamContainer to HL7 message. I run into an error:

ERROR <Ens>ErrBPTerminated: Terminating BP JSON2HL7 # due to error: ERROR #5035: General exception Name 'Parsing error' Code '3' Data ''
> ERROR #5035: General exception Name 'Parsing error' Code '3' Data ''

The code is in this GitHub repo:

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?

Morning everyone,

I would appreciate some advice please- hopefully there is plenty of experts out there.

We are setting up an sFTP share between hospital trusts here in the UK and I have set the outbound operation up using a custom extension of EnsLib.HL7.Operation.FTPOperation.

We are configuring a VPN tunnel to run between the sites also so there is a bit of firewall / network routing to take place to enable the connection but to add in a complication we are on a mirrored cluster and usually present on a Virtual IP address.

Hi all.

I have a scenario where I am receiving NACKs and I'd like to adjust the error handing of the operation based on the content of the NACK.

For example, I could receive the following and want to move onto the next message:

MSH| ^~\&|||||20221025083135.489+0100||ACK ^A02^ACK|9271|D|2.5.1
MSA|AE|1664378390234
ERR|||207 ^Application internal error ^HL70357^^^^^^Cannot transfer patient, encounter is cancelled.|E

However, I could also receive the following and want to keep retrying:

Hi all.

I have setup a HL7 Operation using the HTTP adapter, and I'm getting what seems to me as an unusual response. When sending a sample message to the operation, I am getting a nested ACK. For example:

MSH|^~\&|||xxx|xxx|202209230806||ACK^HTTP^200|00|D|2.1|1
MSA|AA|RWSD7V5iuEC5F6zscDWz|HTTP ACK 'HTTP/1.1 200 OK' : MSH|^~\&|yyy|yyyy|xxx|xxx|20220923080633||ACK^A01|1663916793965||2.3||||||
MSA|CR|RWSD7V5iuEC5F6zscDWz|Error Message Goes Here.

I am trying to split a HL7 message (RDE O11) into several messages depending on how many RXC segments there are in the message (Two RXC segments would need to two separate HL7 messages)

I have seen a couple of posts regarding this but am struggling with my BP using ObjectScript, the idea is to take the receiving message and split this before passing it onto another BP

Here is my code so far

Routing ACKS.

I'm trying to get an ACK routed to a different process in our Test environment and here is the router setup:

I have a rule in the target router to send to an operation.

The problem I'm running into is that the HL7 ACK coming back is marked as "Discarded", so it's not even getting to the second router.

Hi ,

We have inbound HL7 message we want to transform. Is it possible to copy inbound NTE segments at ORC level to PID group level in the transformed messages? I see functions for insert / append / set etc but they appear to be related to specific properties / fields of segments as iodised to the entire segment.

thanks

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 my fellows camrades,

I have a question that seems really simple but it's quite a pain in my ass right now.

I had to rename (take a file from a directory and move it to another) which is a .hl7. Whenever this file has been displaced, I have to change the extension from .hl7 to .OK without using the rename method. Maybe using the attribut?

Do you have any ideas how I could do it?

This should follow the step i have explained right before.

I have a service to take the file but i need an operation to rename it then change his name.

Cache Query for HL7 NACK

I would like to capture any NACK's that is sent back to the Operation. The Operation is already setup to "Save Replies/IndexNotOK's", but I would like to see if we can query Cache and pull those NACK's into an extract.

Is this possible?

Thanks

Scott

Hello,

I want to access the HL7 Router settings from within the HL7 rule. Goal is to create a New class by extending "EnsLib.HL7.MsgRouter.RoutingEngine".

Then create a PARAMETER ProcessMessage which can be set to an integer value for the HL7 Router.

Create a Rule class and based on the value of this setting ProcessMessage
process/not process the messages.
