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..

Opening Files Within A BPL

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.

I'm trying to get a text value of a xml node of a XML Document through the xpath activity within a BPL diagram.

I set the source to Request and all the other properties.

The error I always get back is Method does not exist...

Could anyone help me out?

Kind Regards

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> ?

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.

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.

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.

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...

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?

We would need to know the Ens.Response SourceConfigName to identify which Operation has raised an exception.

We have tried:

$$$LOGINFO("..%Process.%PrimaryResponseHeader.SourceConfigName..: "_..%Process.%PrimaryResponseHeader.SourceConfigName) //It outputs an empty string
$$$LOGINFO("response.SourceConfigName: "_response.SourceConfigName) //It generates an exception


We would need to get from an Ens.Response which body is null, its SourceConfigName:

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.

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?

Hi All


I have a BP which has a transformation. 

when I run the process I end up with the following error: 


ERROR <Ens>ErrBPTerminated: Terminating BP Propirion.BP.GetServices # due to error: ERROR <Ens>ErrGeneral: Object is immutable
ERROR <Ens>ErrGeneral: Object is immutable 


I have created a context named : HL7Message  type of: EnsLib.HL7.Message  and in the start of the BP assigned the request to it  (using set in assigned activity)


What did I miss ?

Actually I am trying to implement a RESt API where in I will get ZIPCODE as request and I need to call external API which will take ZIPCODE as input and give State and City in response.

But the problem is the request is in XML Format and also response is in XML format.

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 am trying to use EnsLib.SQL.Operation.GenericOperation for retrieving (multiple) rows. But I am looking for a way to handing a StreamContainer returned by the operation, in my business process such as receiving it in the Context object and packing it to a request to call another business operation.

Does anyone have sample code to do this?

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?

maybe I am not looking in the correct spots, but how should one handle an Exception from a SOAP web service within the Business  Process Language? For example I am sending a request to a Web Service to try to get information, but the response I am getting is an Exception like "Patient Not Found".


Is there a function I can call to check the response similar to what I do to check a SQL Snapshot to see if it is valued?

I have a call in a business process that returns a response which may contain a collection of error message. I use the following code in my response builder to extract the messge value from the first error and map them to a context variable:

Set    context.ErrorMessage   callresponse.result.GetAt(1).errors.GetAt(1).message
