I am creating a BPL using the Management Portal instead of creating a custom class.

As per the documentations 'request object' contains properties those were in the original request message object or primary request and can be reference using the dot syntax.

So if the primary request was an HL7 message, i should be able to pull the value MSH:9.2 as follow

request.{MSH:9.2} and assign it to a context property

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.

Folks

1) What's the correct way to check for an existence of a segment? So far I have been doing this by checking to see if a required field is non-null, and this seems to work but is a bit clumsy. In this case, it’s an X12 message being checked in an IF action in BPL:

request.GetValueAt("NTE(1):Description")'=""

Or in a DTL, to see if a Z segment exists:

source.{ZEF:Counter}=1

I created a DTL to do HL7 mapping. The test function in the tools works the DTL perfectly but when used by the rule in my business process, the OBX segments are stripped and the MRN is gone. The assigning authority and ID type are added into the PID but the actual patient MRN is blank (3.1 value).

Here is the source code.

Count Number of Pages?

Hello,

We are working on creating a metadata file to accompany PDF documents produced by one of our third party systems for ingestion into our DMS. One of the pieces of data that the metadata file must contain is the number of pages of the PDF document.

In Cache ObjectScript does anybody know if there is currently a way of counting the number of pages within a file (specifically a PDF) without invoking a non-Caché ObjectScript program/function from within Caché ObjectScript?

I have an XML I am sending to an operation from a BPL. This is a query for Patient information from Epic using a web service. I created the operation using the add-in in Studio. I setup the BPL to do a Call and send whatever data I receive from the client. I get a response back from Epic with a list of matching Patients. In the BPL I am trying to use the Response Builder to pass the response ID, name, DOB, etc. to matching context items to then pass to the client as a response. I get the following error within the call:

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?

Thanks

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!

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 ?

Thanks

Gadi

Using Snapshots in BPL

I have a scenario where I am calling a business operation which populates and returns an EnsLib.SQL.Snapshot via dynamic SQL to a Business Process. I then want to iterate over this snapshot and call a RecordMap Operation to write those records to a delimited file.

Is this the correct way to do something like this? If so, does anyone have a sample which illustrates its correct usage?

When the snapshot is returned I save it into a context variable with:

set context.Snapshot=callresponse where the pOutput variable of the operation is set to EnsLib.SQL.Snapshot.

I installed Atelier on Windows in order to take a look at how the BPL and DTL graphical editors accessible via the "Open diagram editor" action work. The diagram editor is opened but I get the following error:


Message from webpage
---------------------------
Unable to load SVG diagram. Please ensure your browser is supported for portal access.


It looks like Atelier uses IE in order to display the editor even though my Windows default browser is Chrome.
