I need to set and use some context variables in a transformation (written in DTL), but the code is manually written.

When writing the same as BPL I define context variables and they are visible in transformations called by that process.

In something like this my.DTLtransform sets HL7 message fields to values in context variables:

Set dtl = ##class(my.DTLtransform).%New()
Set qStatus = dtl.Transform(pRequest, .msg)
 

However, when I create a business process using custom code option, I don't see an obvious option, as well as documentation covering that area.

So we have a custom business service that we use and we are calling SendRequestSync.

Set tSC=..SendRequestSync(tOneTarget,tTargetStream, .tResponse)

For our response from our custom business operation, we send back an Ens.StringResponse.

set pResponse = ##class(Ens.StringResponse).%New()
set pResponse.StringValue = "File Delivery: "_tOutFilename_" of size: "_pRequest.Stream.Size_" (modified='"_pRequest.Stream.LastModified_"')"_" Status: "_tSC
 

In 2017, Forbes published an article talking about API Economy (see: https://www.forbes.com/sites/louiscolumbus/2017/01/29/2017-is-quickly-b…). This article was the trigger to popularize the use of API and API Management by large companies. The article published a maturity model. My understanding is that Intersystems IRIS allows you to reach the top of the pyramid with your current technologies. See the figure above.For this it is important to combine % CSP.REST package, IRIS API Manager (IAM), ML Pack and IntegratedML, Native API for Python, BPL and

I've got a REST service that I can access via a browser. I can get it to take HTML tags as data and display it back to me (so I know the REST part is working). So if I send it this:

http://MyServer:57772/TestArea/rest/TestQuery?UUID=1&RTX=RTX123456&CareType=Palliative
 

Then I can pick out the data and tell it to display in the browser, which is great but what I really want to do is put the data into a string and send to a business process that will do lots of looking up but eventually return a URL that my REST service will then redirect the browser to.

In this article I'd like to share with you a phenomena that is best you avoid - something you should be aware of when designing your data model (or building your Business Processes) in Caché or in Ensemble (or older HealthShare Health Connect Ensemble-based versions).

I am developing a BPL with a delay process. 

The problem I have is when a message is delayed I cannot see a job id so whilst a job is in halt status I cannot see how i can then cancel the message? It obviously doesn't show up in queues as it isn't active either. 

Am i missing something?

Hello,

We are developing a BP where we would need to call at the same time to get appointments in two external systems. So then, we would need two threads, one for primary care appointments, and other for specialist appointments . We need to paralelize both calls because of both of them require some time and we would need to shorten it as much as possible.

We are currently using a flow:

when ever I pull the xml file from business services and its failed in business process and I am getting the below error. ERROR <Ens>ErrPreviouslyCrashedMessage: Message '117' crashed previously.

I want to send requests from custom BP with timeout and be able to understand that timeout event happened.

I thought that I need to implement OnTimeout method in my process (in either caller or callee), however it seems like OnTimeout  is never called.

Let's say we have this parent process:

I have a code block in a BPL.  I have the below SQL and code.  All variables have been declared and set.  When I run the SQL, if there are no values returned, I get 100 for the value of SQLCODE when I perform the FETCH, which is correct.  If values are returned, I get a -400 error when I perform the first FETCH.  I've investigated, but cannot find the reason for a -400 error.  Hoping someone out here understands this and knows what's wrong.

In a HTTP operation, which extends Ens.BusinessOperation, EnsLib.REST.Operation, one can read the component's AlertGroups property by simply referring to it with "..":

set AlertGroup =  ..AlertGroups//Do something with AlertGroup

"AlertGroups" is a property of Ens.Host. The above however  does not work in a business process which Extends Ens.BusinessProcessBPL which extends Ens.BusinessProcess which extends Ens.Host. Can this property be read from inside the business process and what would the syntax be? 

I have two files that I ultimately need to combine.  The first file contains data from a PO.  The second file contains tracking information.  What I thought about doing was create a BS that grabs the first file, loads it into a record map and transfers it to a BPL.  Then, the BPL would open the second file where I would write code to load the file into a second record map and then insert the tracking information to the correct places in the first file based on PO line items.

Hi everyone,

I am very pleased to announce that the Readmission Demo has been released as open source. Many thanks to the Solution Factory team that worked hard on making this possible.

Here are the changes:

Hi Community,

New video, recorded by @Eduard Lebedyuk, is available on InterSystems Developers YouTube:

⏯ Python Gateway: Jupyter Support - extended

I am working on a BPL to take data from a MS SQL database and create an HL7 Materials Message for our EMR.  I have done this plenty of times in the past however I am running into an error.

"Remote Gateway Error: JDBC Gateway SP execute(0) error 0: Access to the remote server is denied because no login-mapping exists."

What is confusing is that this BPL doesn't differ from any of my other BPLs in connecting to MS SQL Server. I know I am missing something..

This BPL will execute the 1st Stored Procedure without any issues, the issue is when it comes to executing the second stored procedure.

This series of articles would cover Python Gateway for InterSystems Data Platforms. Execute Python code and more from InterSystems IRIS. This project brings you the power of Python right into your InterSystems IRIS environment:

• Execute arbitrary Python code
• Seamlessly transfer data from InterSystems IRIS into Python
• Build intelligent Interoperability business processes with Python Interoperability Adapter
• Save, examine, modify and restore Python context from InterSystems IRIS

The plan for the series so far (subject to change).

We're back with more AI, more ML and more presenters!

We are pleased to invite you to the upcoming webinar in English: AI Robotization (Python, R, Interoperability) for InterSystems IRIS on November 7 at 11:00 EST!

HI

We can easily do a <call> from graphic BPL's

I was wondering what is the best way we can call another Business Process or Operation via code.

Thanks in advance

Hi,

I am sending a request message to Business Process which has one property as Dynamic Object type. So i get the JSON in my REST service and convert that as a dynamic object and set that in the request message and calling the business process from the business service. But the request is not getting sent to the Business Process. Is it possible to send dynamic object input to the business process.

Greetings,

I am trying to test an hl7 message inside studio and when I click on the test button I get this error:

"<FUNCTION>GetProp+2^%CDCalBk"  at  9:51 am.   $I=/dev/null:50333010   ($X=0  $Y=54) $J=50333010  $ZA=0   $ZB=""   $ZS=65536 ($S=66023400)

I have never seen this before! Any suggestions?

Here a simple test message:

I have several BPL's that act like SQL Server Integration Services (SSIS) where they are transferring data. When I do this they are all being written under 1 session id, is it possible to make the BPL create multiple session ID's as it is cycling through a Snapshot, so it is easier to read in the trace?

Thanks

Scott Roth

I'm writing "Finder"-like dialog and need to get list of BPL classes.

The query is dependent on current "path" - it outputs all BPLs in the current path (if any) and all sub-packages which contains BPLs.

So far I have this query:

Query getBPL(path, needPlus = {(path'="")}) As %SQLQuery
{
SELECT DISTINCT $PIECE(Name, '.', 1, $LENGTH(:path, '.') + :needPlus) Name
FROM %Dictionary.ClassDefinitionQuery_SubclassOf('Ens.BusinessProcessBPL')
WHERE Name %STARTSWITH :path
}

My problem is, if I'm not in "root" path I need to add additional dot level, but in root path I only need to add one.

I have BPL BP and BO.

To call BO I need to populate the stream property of the request message.

What's the best way to do it?

From inside Business Service (OnProcessInput method specifically) I want to determine if Ensemble tries to shut down the job.

Is it possible? How?

Hi all, My first post. I hope I have created it correctly.

Our team is looking to increase the number of characters in our Ensemble 'Categories' for Services, Processes and operations.

We are doing this to better identify things like Vendor, Message type and integrated application names...

One of our team members thought his might increase processing overhead and a discussion ensued that was not resolved.

my thoughts...

Hello,

We have a BPL that returns in Response several %Strings, Dates. When we try to add Array of Objects property to the Response we verified just before the BPL terminates the response object has correct values in all properties including the array. We checked the Count().  It appears that even array of String works correctly but we prefer to pass objects rather than strings.

When it comes to Response Builder in the calling BPL, the array of objects property in callresponse is not a valid oref, it appears to be missing, other properties of types string or date are valued correctly.

How do I send request on production start?

Here's what I got so far in my production class:

ClassMethod OnStart(pTimeStarted As %String) As %Status
{
    job ..InitialTraining()
    quit 1
}

lassMethod InitialTraining() As %Status
{
    hang 5
    set sc = ##class(EnsLib.Testing.Service).SendTestRequest(...)
    quit sc
}

Is there a better way without hang, etc?

Is there a way to have a context property be available across 2 or 3 different business processes? For example if I am setting a value in a context property within one business process and want to use the same context property in a second business process, is this possible? Is this something that can be done with the "Context Superclass"?

Hi community.

I need to get the parent classname of a class, but I don't find how to do it.

I have a class Parent  (MyLibrary.ParentClass) and two classes inherited from the parent class

MyLibrary.ParentClass

       ├─── MyLibrary.ChilcClass01
       │
       ├─── MyLibrary.ChildClass02

I have a Business Process that entry class is MyLibrary.ParentClass. If I'm calling with any child class (i.e. MyLibrary.ChildClass01) it works, then I'm using the method $Classname(request) to get the name of the class and redirecto to other process.

In a Business Process (BPL) I noticed that if I 'm using a "scope" to handle errors  then inside the "scope" when a "call" is used, the "request" and "response" action (i.e set for callrequest.prop = request.prop & response.prop = callrespones.prop does NOT work !
The result is that the values of those properties in the callrequest  are nulls (I do see the properties names in the content of the callrequest message)
