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?

Suppose I have an image and need to convert that image into a PDF for inclusion in an HL7.

I know that Zen Reports can display an image in a PDF but I do not want to view the image in a web page. I just need to convert the image to PDF in a Process and then include that PDF in an HL7. The workflow would be like this:

Get image -> Convert image into PDF -> Include PDF in HL7 OBX.

I know how to do the last part to include PDF in HL7 OBX. Just need ideas on the first part.

Single Row SQL.Snapshot

I have several stored procedures that when I execute them they will only return a single snapshot. In my BP I have been setting this to a Snapshot variable then looping using a WHILE through the snapshot variable just to get that single value.

Since it is only a single row, is there an easier way where I don't have to do a WHILE loop to pull the values out of that row? Can I call First Row or something like that to get me just the row into the Snapshot variable?

I have a Business Service that reads a file from a folder and sends it as a string to a Business Process. In the business process, I need to add a string to the end of the file string that is coming into the Business Process. I am trying to do this in object script in studio and I am struggling to figure out how to add the string to the end of the other string. I am still new to studio and object script I have been reading up on the documentation and I am not sure what is the best way to accomplish this.

How do we trigger a BPL Business Process on a time schedule?

We are building a production that takes a steady stream of (HL7) lab results messages, processes them and stores them in a temporary database table. At scheduled points during the day (eg 0800, 1300, 1600) the database is queried and messages sent on to the downstream system. Aiming that the Processes to be implemented in BPL if possible - but we are having trouble triggering code in a BPL as a scheduled job.

API Response truncating?

I have an API that does not have all the data. Like it is truncated. Magic number of characters seems to be 163,280

I do an <assign>

context.RawBundle=##class(%DynamicObject).%FromJSON(context.FHIRResponse.Body)

The error does not happen when the response is < 163,280 chars. And when < 163,280 chars, it is a complete FHIR Bundle. Have anyone experienced this? If so, what is the resolution?

What are the pros and cons of developing a custom database driven routing engine vs. using the Ensemble standard routing engine. What I'm trying to accomplish with the custom routing engine is less manual intervention every time a new route is added. The con I can see with the custom engine is performance may lag behind the standard engine. My development vs. Intersystems essentially.

I appreciate feedback. Thanks!

I am calling a business rule from one of my business processes and I noticed that when the business rule reports an error that the business process calling that rule just stops without any errors. Resultingly it fails to trigger the scope - catch-all construction that is surrounding the business rule. I know that it is possible to view the errors in business rules in the business rules log, but I really like to push an error message to Ens.Alert or something similar when my business rules report an error. How do I achieve that?

Hello,

I need to access the value of a setting I created (ex: name_BO) within the logic of my BP.

Property name_BO As %String(MAXLEN = "");

/// Additional Settings 
Parameter SETTINGS = "name_BO:Basic:selector?context={Ens.ContextSearch/ProductionItems?targets=1&productionName=@productionId}";

But the class is common and the production item names will change.

Greetings,

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

I have never seen this before! Any suggestions?

I am using the EnsLib.File.PassthroughService class in the business service, this business service will accept a text file from a location and pass it through to the BPL as a stream. I have been trying to work with the BPL in the GUI and I have been reading the documentation and trying to get it to work but I can not I continue to get errors and I am not sure why.

I will attach the Photos of what I have been trying, I think there is a problem with my call action because when I try and trace the message the context of the file does not even make it to the business operation.

I have a use case where Epic is sending an A60 Allergy transaction is set at the Patient level, but we have a system called VIBE which needs the ADT at an Encounter level instead. Currently we store ADT information in a MS SQL database for years, and we are querying it to get the latest Account Number to insert into the ADT^A60 for VIBE.

Hi all,

We're in the process of creating several courses for creating custom business components for productions. This includes custom business operations, BPL processes, and custom business services. Custom Business Operations and Custom Business Services are both aimed at software developers while BPL processes can be also be created by business analysts. What are some gotchas or best practices you've learned that you wish you knew when first building these components?

We'd love to include what you've learned into these courses so others can learn from them as well!

Decoding Base64 PDF File

Hello, I am writing some cache code that will pick up a PDF file, Base64 encode the contents and then send on to a third party system within a Long String (via their API). I have been testing this and discovered that the PDFs do not open within the supplier system (I get an error saying that it hasn't been decoded correctly). I wanted to prove that the issue does not lie with the way that I have Base64 encoded it within Ensemble, and therefore as a test wanted to Encode the PDF stream, then decode the stream and write out to a new file.

Hello, we have a couple of BPL processes. This works with a limited amount of messages but we run into issues when we process thousands of messages in a session. One BPL calls a Validation BPL process with async='False' and there is a response defined. The timeout is two seconds and that seems to be plenty of time for the validation process. I expected the calling process to wait for a response but that is not happening.

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:

Hi there,

I'm working on a project where I retrieve RawHL7 message(ORU R01 2.3.1) content from a database in a BPL. I've created a context object of type Enslib.HL7.Message, and I need to populate it with the contents from the RawHL7 message so that I can use this context object as source for my DTL transformation.

Does anyone have suggestions on the best approach to achieve this? I'm looking for guidance on how to efficiently transfer the data from the RawHL7 message to the context object.

Thanks in advance for your help!
