#Business Operation

Hello everyone. I'm currently working on how to implement a solution that makes it possible to include within the response of a BusinessOperation the "RetryCount" for each message.
For Example, we have this message that was retried twice:

This is an HL7.message going through a specific business operation, we did not create a custom one: we used the default implementation EnsLib.HL7.Operation.TCPOperation. This operation should automatically handle retries (infinetely waiting on a response).

Hi,

I want to consume an API that provides HL7 messages. To achieve this, I have thought of the following workflow:

I have created a business service that periodically triggers a business process. The trigger request is forwarded to a business operation. There, a %Net.HttpRequest is assembled from scratch and then sent to the API endpoint. The corresponding HttpResponse then contains several HL7 messages encoded in UTF-8 in the message body. To further process the HL7 messages, the operation sends the HttpResponse back to the business process as EnsLib.HTTP.GenericMessage.

Hi, I have simple email alert setup (EnsLib.EMail.AlertOperation) where in operations I have SMTP server setup and Recipients emails.

Also I find Alert Groups dropdown option in operations, processes, how this is different from setting up simple email alert with recipients list?

Please advise.

Needs some help with FHIR return code 200 or 201 when processing HL7 messages in HealthConnect.

Issue:

1. If FHIR code is 200 or 201, HealthConnect keep processing HL7 messages

2. If FHIR code is NOT 200 or 201, HealthConnect keep suspend the HL7 messages in the messages queue, then keep processing NEXT subsequent HL7 messages in the TEXT file if the FHIR code is 200 or 201

3. I am also using following "Reply Code Actions" in Operation settings (:?R=S,:?E=S,:~=S,:?A=C,:*=S,:I?=W,:T?=C)

Please advice if I have a "if condition check" for FHIR codes 200 or 201, what "Reply Code Actions" I should use?

Using a WSDL and the SOAP wizard I created a WebServiceClient, and Operation to send an encoded message to a Vendor. But the vendor is now sending back an HL7 in the SOAP response.

I tried updating the Operation to Extend EnsLib.HL7.Operation.ReplyStandard, but still use the EnsLib.SOAP.OutboundAdapter. When I did this it broke my Operation and would not compile with the following error...

ERROR #5478: Keyword signature error in osuwmc.Nutrition.HL7SoapOperation:Method:SendMessage, keyword 'method argument/s signature' must be 'EnsLib.HL7.Message,EnsLib.HL7.

Working on interfaces, trying to add simple email alert (link below) under "Operations"

https://docs.intersystems.com/healthconnect20231/csp/docbook/DocBook.UI…

if the message is good,  health connect processes ok.

if the message has an ERROR, it held up the message in Queue (keep retrying), then subsequent messages held up in the queue as well to be processed. Because of the message held up in Queue, Operation for TCP connection also turning blue.

Please advice.

Hello,
I am currently facing the task of retrieving or sending HL7 messages from a web API. Since we only send HL7 messages via internal sockets, web APIs are relatively new to me.
The following is my plan for the new interface:
I have created a new custom business service that periodically sends requests to a business process. In this business process, the HTTP request (HTTP.GenericMessage) is then created from scratch. The special feature is the "Authorisation" header field, where a signature is inserted, which consists of a base64-encoded hash value.

We are trying to mark a hl7 nack as "completed" to ignore an error and not generate the alert. 

We can remove from adding a managed alert or add another router in 

When Nack of CR of 

Date of birth in PID.7 must not be empty

We tried via this but i think it's only for an actual IRIS alert errror not the HL7 error code/description 

E*Date of birth in PID.7 must not be empty=C,:?CR=C,:?R=RF,:?E=S,:~=S,:?A=C,:*=S,:I?=W,:T?=C

Our vendor is developing an interface API on their end to capture HL7 data on a Server Port, and they require us to send a pre-defined HL7 Order message for testing every hour until the API is completely operational.

Is it possible to accomplish that in a Business Operation automatically without utilizing a service or process? The BO is a standard TCP/IP connection.

I'm manually sending the message again from the Operations right now. I do not have access to the System Operation to use the Task Manager feature.

We currently have Business Operation that we built to use the EnsLib.SQL.OutboundAdapter so we can make Microsoft SQL Server Stored Procedure calls. The BO is attached to a Java Gateway Service.

Some of our MS SQL Databases have moved from being OnPrem to Azure Cloud. We have started seeing where we are receiving errors on the BO saying that we cannot connect to the Azure Database, but we never receive a Disconnect from the Azure Database.

Given:
class Foo.Bar extends Ens.BusinessOperation
{
Parameter SETTINGS = "Whatever:Basic";
}

class Foo.Baz extends Foo.Bar
I want to somehow drop "Whatever" as a setting from Foo.Baz. How can I do this?

We have a vendor that is requiring that the HL7 sent to them is sent as an Encoded message inside a SOAP request but is sending back an HL7 message as the response. 

When the WSDL built the response, it was expecting an encoded message back. I updated the Request and Business Operation to expect an EnsLib.HL7.Message, however I am not sure how to handle the HL7 ACK to post it back to the sending message so it will not cause an Orphan message, and to parse it back correctly in the trace viewer.

When I do a $$$LOGINFO on the pResponse, I get back...

I am having issues trying to send SOAP requests to a Cloud Based AWS Application that lives outside of our network. 

It is using a Basic Authentication, Key, Certificate Authority and Whitelist for Security. 

If I attempt the connection using wget from the command line I am able to connect,

:>wget --bind-address=10.95.129.245 --server-response https://xxxxxxxxxx/xxxxxxx/services/Mirth
--2025-06-06 15:54:51--  https://xxxxxxx/xxxxxxxx/services/Mirth
wget: /ensemble/.netrc:16: unknown token xxxxxxx
wget: /ensemble/.netrc:16: unknown token xxxxxxxx
Resolving xxxxxxx.com (xxxxxxx). 34.233.89.

I am having a hard time trying to figure out the following...

Within a DTC, I was able to take the a EnsLib.HL7.Message source and using

set a= $System.Encryption.Base64Encode(source.RawContent)
set encodedMessage=$Get(a)

to take the HL7 message encode it and add it to the Data Class as a string to be sent to an Operation to be sent out as a SOAP Request. 

However to make it more universal I tried doing this within a copy of EnsLib.HL7.SOAPOperation

Method SendMessage(pMsgOut As EnsLib.HL7.Message, Output pMsgIn As EnsLib.

WSDL for a CDC vendor was provided with a URL using a custom socket (non 443). Everything generated fine, but when making calls to their https:// URL that has their custom port in the URL - no response comes back. The assumption is, their server isn't even processing the request, as Postman does using the custom https://path.to.server:NNNN port in the URL.

I see with a normal web operation that uses %Net.HttpRequest overriding the port property is easily done - but no animal seems to exist for any generated SOAP Operation class.

Hi,

We're having an issue with some messages being sent to a downstream system from Healthshare.  Part of the free text in the NTE segment is displaying with special characters on the system front-end but is not present in the HL7 message that we send to them.  We are guessing that this is a result of some of the text being copied and pasted from something like MS Word. The '?' on their system is just representing an invalid character. 

Is anyone aware of a way to prevent this occurring? We are sending the messages using the 'cp1252' encoding.

Trying to start investigating an error we are seeing with multiple of the same messages getting sent to the same vendor. We receive an HL7 message with an RTF embedded from our EMR, send it through a DTL to just update the Patient Class, and then send it onto the Operation which is TCP.

We are starting to see this error message...

ERROR <Ens>ErrBPTerminated: Terminating BP DocOutRptRouting3M360 # due to error: ERROR <Ens>ErrException: <INVALID OREF>zOutputToIOStream+6^EnsLib.HL7.Message.1 -- logged as '-' number - @''
> ERROR <Ens>ErrException: <INVALID OREF>zOutputToIOStream+6^EnsLib.

Hello,

I tried to define Pool Size in System Default Settings, but it is not being used. I see I am not the first to try this without success:

Any suggestions?

Hi,

My HL7 interface in production is outputting messages to a HL7 File Operation and a  EnsLib.HL7.Operation.HTTPOperation. There is no errors in the File Operation, but the HL7 HTTPOperation is giving ERROR #5911: Character Set 'iso-8859-4' not installed, unable to perform character set translation.  Both the HL7 File Operation and HL7 HTTP Operation are using latin1 for Default Char Encoding.

What is ERROR #5911 about? Is something missing in the IRIS installation? 

Thank you.

We are calling a REST web-service from Ensemble using EnsLib.HTTP.OutboundAdapter and redefining the adapter class to set custom headers as described by @Eduard Lebedyuk here: How to set Content-Type

During development we accidentally stumbled across puzzling behaviour - we now suspect that the %Net.HttpRequest object created in the linked example is being reused in the following scenario:

1. request is created as described and sent to web-service, so an instance of a %Net.HttpRequest object exists and is known to the EnsLib.HTTP.

What is the recommended library for converting documents to pdf. Any suggestions welcome has anyone out there had a use case where they had to convert documents to pdf .What worked for them .I have asked WRC for the best practice and they have recommended that may be  a sale engineer might have an answer to this .

I have an operation using $ZF this operation ran and did not error but the job has been active and it can not be stopped I have tried stopping it from the front end and through the terminal using ##class(ENSLIB.Job).%New() Stop method. Now my production will not update even if I add a new item to the production I cannot update the item is there a way to force stop  this job.

Hello,

I hope this is a simple ask..

basically I need to create local files daily at a certain time for example 11:30pm.

1. file name needs to be like  xxx__20250113.txt , the date part should be next day's timestamp with format YYYYMMDD, so I will write about 17 files like that with different names.

2. write a dummy hard coded word for example “Dummy Word” in the file.  the file eventually will be used by other operations to add hl7 message on top of this  in it with the live interface message. 

3. this needs to be done every night at 11:45pm

So how am I going to implement this?

I am developing a business operation that receives a request, creates a message with the data contained in it and sends it to an outlook email. For testing purposes both the sender and the destination are the same email account
This is the code:
ClassBO.AlertEmailSenderExtendsEns.BusinessOperation{

Hi all,

I'm wondering if it is possible to call a Business Operation from other Business Operation.

I have a BO that writes logs into a database, using a personal message. I can create a set obj=##class(MyLogs).%New() but the BO has all parameters about connection.

Is it possible?

Best regards.

I have been trying to track down an issue we are seeing in our TEST environment with Memory usage.

We have Several BP's for years now that take a HL7 message, parse it apart, and make calls to a Custom EnsLib.SQL.OutboundAdapter to have it execute Insert/Select/Update/Delete stored procedures against a MS SQL Database via JDBC connection. We are using Microsoft's JDBC 12.2 driver to do this.

What we are seeing is that IRIS.WorkQueue globals are being defined for these calls but then the IRIS.WorkQueue is not being cleaned up and taking up large amounts of Memory.

Hello all,

On one of my team's systems, we utilize a business operation with the EnsLib.SQL.OutboundAdapter to make SQL queries to another IRIS system using JDBC. To authenticate the connection, we utilize a user account on the target system.

We recently had a failure where this user account expired due to inactivity, causing all queries to error until the account was reactivated on the target system.

I have a question about using OnInit() within a Ens.BusinessOperation.

When you include OnInit(), does OnInit() only execute when you start a Business Operation? Or does it execute OnInit () every time you send a REST request to the operation. I am trying to pinpoint when the best time is to execute the POST command to get the Token

I am needing to get a Bearer Token from a REST POST call and return the Authorization key prior to making the rest of the REST calls to pull down data.

When not using OAuth, what have you done to get the Token prior to executing any Requests?

Thanks

Scott
