#Business Process (BPL)

InterSystems Ensemble Business Process Language (BPL) is a language used to describe executable business processes within a standard XML document.

Documentation.

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!

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
> FEHLER #5002: Caché-Fehler: <MAXSTRING>zgetAtFromArray+46^EnsLib.HL7.Segment.1

Hello,

We have defined four BPL Business Processes. One gets occasionally errors when pool size is two. No errors happen with pool size one. The error happens on calling %Save() on a large objects with many references to other objects.

Error #5803: Failed to acquire exclusive lock on instance of 'classname'.

Error #5002: Cache error: <ROLLFAIL> %TRollBack+10^%occTransaction

The error happens on a particular large object.

Our FileService gets the same Errors #5803 and #5002 with class 'EnsLib.EDI.X12.Document'

Hello All,

I am exploring Ens.Alert to generate alerts for Server exceptions.

I noticed that in the business operation, if you have your code inside try/catch and if your catch doesn't explicitly invoke $$$systemerror then Ens.Alert is not invoked.

Similarly, in the Business process if you have <catchall> then Ens.Alert is not invoked on error. How can I invoke Ens.Alert from <catchall> ?

Is it possible to dynamically adjust the RetryInterval andFailureTimeout settings in a BPL?

I've got a business process that calls a web service operation to get a session ID from an external system. There is a string property returned in the body of the response that indicate an exception occurred in the external system. I have code in the BPL that examines the property and sets the status property to an error status when that occurs.

I have a production that takes in an HL7 message thru a business service. The business service passes the incoming HL7 message to a business process that calls a transform to transform the HL7 message to a message class. After the transform is finished, the business process uses a code block to pass the object created by the transform to a method class that processes the data in the object. What would be the correct syntax for passing in the object to the class method?

Ran into an issue this morning, that I am having a hard time trying to track down what might have caused the issue. We have a Business Rule that sends HL7 ADT to a Business Process that inserts the data into a MS SQL Server using a Custom Business Operation (SQL Outbound Adapter).

I have a handful of EnsLib.HL7.MessageRouter sending an HL7 message to a single Business Process (Ens.BusinessProcess).

In the OnRequest method, I am declaring pRequest as EnsLib.HL7.Message

What I need to do is determine which HL7 Router sent any given request to my BusinessProcess.

To do this, I know that I need to fetch the SourceConfigName property from the Ens.MessageHeader of the Request, but I am not sure how (or if) I can fetch this data from within the OnRequest Method.

Does anyone have any pointers?

I'm looking at an issue where I need to grab an ID number from an external SQL table when it doesn't exist in a HL7 message, and then add it to the HL7 message.

I have built the logic within a BPL which checks for the lack of ID, and then pulls the ID from the SQL table (and storing its value using the context functionality within the BPL) however I am at a loss as to how I then take the ID and add it to the HL7 message before passing it to a router.

SQLCODE Error -400

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.

I created a custom class for a process that does some basic manipulation to an HL7 message. I'd like to be able to write some debugging to the process event log. How would I do that?

I've tried ##class(Ens.Util.Trace).WriteTrace("system","HOSP.IHE.PDQProcess","MessageHeaderHandler","Discarding input message")

but I get a runtime error when I try that. I know this is pretty basic stuff, but any help would be appreciated.

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.

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...

There has been some confusion about how to edit Business Process Language (BPL) and Data Transformation Language (DTL) files in Atelier using the graphical editor. The following steps describe how to do this with Atelier version 1.0:

Copy the file you want to edit from the server to an Ensemble-enabled project in your Atelier workspace. To do this, find the file in the Server Explorer, right click and select Copy to project.

Open the file in the Atelier class editor just as you would any other class file.

I have a batch record mapper that reads a csv file and passes the message to a process that uses the EnsLib.MsgRouter.RoutingEngine and would like to pass the message to an operation that will output that as a XML file but so far been unlucky as the operation that I use , uses the EnsLib.EDI.XML.Operation.FileOperation which only works with the messages("BusinessOperation class for writing XML messages to a file.

1.Can anyone share few details how to save Non HL7 message into SQL table and the converted HL7 message into SQL table

2.In Message Viewer is there any SQL tables are linked to the session id or where the information regarding the message will be stored? Will the message trace details are stored in globals or in SQL table,If yes can anyone share the details in which tables or globals will it be stored?
