When I started my journey with InterSystems IRIS, especially in Interoperability, one of the initial and common questions I had was: how can I run something on an interval or schedule? In this topic, I want to share two simple classes that address this issue. I'm surprised that some similar classes are not located somewhere in EnsLib. Or maybe I didn't search well? Anyway, this topic is not meant to be complex work, just a couple of snippets for beginners.

Hi community,

I have a service that uses EnsLib.RecordMap.Service.FTPService to capture files in an FTP directory.

Instead of uploading them all at once, I would need to do so one at a time.

I have a class that extends this class because it preprocesses, saves everything in the RecordMap class, and then processes all the records at once.

When I invoke the BP, it does so through the method set tStatus = ..SendRequest(message, 1).

I've set the SynchronousSend flag to 1, but it continues processing all the files at once.

Introduction

HL7 messages often contain multiple repeating segments such as NTE, AL1, OBX, ZTX, DG1, and others. These segments sometimes require individual processing and routing to different downstream systems. This technical paper introduces a configurable template designed to automate the splitting of these repeating HL7 segments, improving message handling and integration efficiency.

There is a way to remove the web source control in the web page of BPL?

i already disabled a configuration in the production and works fine:

But in the BPL page, it doesn't worked. There is a way to disable this configuration at portal?

Hi all,

I’m working on a data transformation in IRIS where I need to calculate the difference in hours between two timestamps stored as %TimeStamp.

Example:

Set startTime = "2024-07-12 08:30:00"
Set endTime = "2024-07-12 15:15:00"

I’d like to calculate the number of hours (with decimals, like 6.75) between them. What's the recommended way to do this in ObjectScript? I’ve seen examples using $ZDATETIME, but I’m not sure if that’s the cleanest approach.

Any suggestions or best practices would be appreciated!

Thanks,
Jhonn Marie

I'm creating a Business Process that:

1. Transforms one object into another using DTL
2. Sends this object to an operation
3. Transform the object obtained in first point into another one using DTL
4. Sends the second object to an operation

The Business Process is created with BPL, and objects are stored in BP context. When I execute this Process, in the 3rd point the object obtained in first transformation doesn't exist. It's empty.

I have tried to make transformation before making CALL's, I mean:

Hi,

I've been working on a very basic Interoperability production in my computer. I followed one of the examples in the courses and created a TEST.FileRouterRoutingRule, but when trying to edit this rule, it takes me to the Rule Editor Login Page, where I can't get in (Not even with the _SYSTEM credentials) - Is this functionality unavailable in the community edition?

Artificial Intelligence (AI) is getting a lot of attention lately because it can change many areas of our lives. Better computer power and more data have helped AI do amazing things, like improving medical tests and making self-driving cars. AI can also help businesses make better decisions and work more efficiently, which is why it's becoming more popular and widely used. How can one integrate the OpenAI API calls into an existing IRIS Interoperability application?

Hi, Community!

🐍Great news—you can now use Python to customize your productions and add custom code!

Using Embedded Python in the BPL and DTL Editors

I need a DTL to handle this.

Any ideas appreciated.

For all Prosthetics orders:
when ORC-1(Order Control) is "NW" (New Order), need to update OBR-18(Placer Field 1) based on PV1-2 (Patient Class) value.
assumption is that the selection logic is that all prosthetics orders with OBR-18 field is always blank.
Description :
If PV1-2 is I, insert I in OBR-18
If PV1-2 is O, insert O in OBR-18
If PV1-2 is E, insert O in OBR-18
If PV1-2 is P, insert O in OBR-18
If PV1-2 is R, insert O in OBR-18
If PV1-2 is B, insert O in OBR-18

Hi all,

I can't find the list of business host setting sections and (crucially) how to refer to them in the SETTINGS parameter, as marked in purple here:

Parameter SETTINGS = "MySetting:Basic";

Does anyone know where this list lives?

I have a business service which is responsible for some batch operations with an SQL table. The process is generally slow but it is possible to scale the performance using multithreading and/or parallel processing and logical partitioning (postgres):

select id, col1, col2, mod(row_number() over (), 4) as partition from some_table;

Thus, a partition index will be assigned to each table row. The idea is to create several instances of my business service using pooling (e.g. Pool Size = 4) so each business service instance will be responsible to hande rows belonging to a certain partition, e.g.:

Prompt

Firstly, we need to understand what prompt words are and what their functions are.

Prompt Engineering

Hint word engineering is a method specifically designed for optimizing language models.
Its goal is to guide these models to generate more accurate and targeted output text by designing and adjusting the input prompt words.

I already mentioned in a Previous post I am trying to build a list from a repeatable field within a HL7 message. I figured out how to build the list by using a context list string variable within the Business Process (BPL) and doing a

do context.<variable>.Insert = <value>

 when I am looping through the field. I want to do it one step farther though... I want to search the list to see if the value exists before I do the insert. I only want to insert if the value is different than what is in the list already.

Hello everyone!

I have set up an EnsLib.REST.GenericService with an  EnsLib.HTTP.InboundAdapter which forwards the http requests received by a web app to my Business Process. 

I would like to parse HTTP multipart/form messages I am receving and be able to iterate over the various fields within the request body, accessing its content type and the content itself.

As far as I understand I should use the %Net.MIMEReader class which should return a list of %Net.MIMEPart, one for each field within the request. However if I do : 

I understand that InterSystems provides functions to facilitate transactions between FHIR and HL7 via the SDA segment. My question is:

• Does this transformation only work when InterSystems receives FHIR requests and converts them into HL7, or does it also support responses?
• Specifically, if our operation sends a GET request to a broker and receives a FHIR response, does InterSystems support transforming this response into an SDA segment automatically?
• Or should we manually parse and modify the response to handle it according to our needs?

Hi Community,

I need to remove first tag from a XML file in service and send  file to the  process ,how do i remove line from the File and process it 

Thanks,

I need to use a context variable in my code block for the table to query. When I use :content.table, it does not work.  When using the literal, it does.  How do I get the :context to work?

I have a Service reading a flat file and routing to a Process.  Does anyone know how to get the %Source value into a BPL context parameter?

Very similar question posed here: https://community.intersystems.com/node/467496, but I am missing a piece of this:

How do I correctly call a EnsLib.HL7.MsgRouter.RoutingEngine class from the BPL?I can successfully call the BPL from the EnsLib.HL7.Service.TCPService, and I have the BPL created to delay then call the rule. And I set the context and the result location.

This rule is really basic just sending the HL7 content to a EnsLib.HL7.Operation.TCPOperation

When implementing deferred response there was a problem initially with a few responses which meant we had blank jobs spawned somehow. How do you get rid. All the operation does is:

SET sc =..SendRequestAsync($piece(..ForwardComponentNames,",", i),pRequest,1)

These all sent ok and tried to update status to 9 from 6 hoping it would clear the blank jobs but it didn't . The original issue has been resolved weeks ago. 

To transfer data between production components I actively use messages of type Ens.StreamContainer class and its descendants. In many cases the content of the message content is not visualised (the 'Body' tab contains a table with a list of selected message properties but the 'Contents' tab is empty). Response messages are never visualised, and request messages are visualised with a fifty-fifty probability. What do I need to do to ensure that messages are always visualised?

In a Business Process (Ens.BusinessProcessBPL), how can you correctly call a classMethod?
I know we can call it in a block <code>  :

Or in a <assign>

Are there other ways and/or good practices?
Thanks
Corentin

I want to execute initialization code on the start of my business process.

I thought OnInit is a way to go, but apparently not - ^dbg global remains empty:

Class Test.BP Extends Ens.BusinessProcess
{
Method OnInit() As %Status
{
    Set ^dbg = 1
    Quit $$$OK
}
}

Ideas?

Our TEST environment and PROD environment are on two different versions of HealthShare Health Connect.

Someone within the group wants to migrate a BP from TEST to PROD, however they are running into an error "attribute 'languageOverride' is not declared for element 'assign'" 

Hello,

First of all: thanks for your help, and thank you for your time.

Thanks for your time.

We have the following situation:

We are in a BPL, and we have defined 4 <call> asynchronous as follows:

First one name: "Enviar a Proceso NEGRIN"

The second one, named as: "Enviar a Proceso HUNSC"

The third one, titled: "Enviar a Proceso CHUIMI 02"

And the fourth and last one names as: "Enviar a Proceso Fuertev"

Inmediately after the 4 calls, we have a <sync> instruction which should wait for all of them to finish.

I have a BPL iterating over Dynamic arrays. Can I add Dynamic Array (%Dynamic Abstract Object) and also %Iterator.Array to BPL context? I tried and I see Error: %AddToSaveSet method does not exist for %Iterator.Array

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.

I am still trying to understand and come up with a use case to use FHIR as an enhancement to our existing HL7 messages. Does anyone have an example of taking a FHIR response and transforming it into a SDA?

How does the workflow go? Does it go through 1 BP? 

Thanks

Scott
