Yes, you can loop through items in your source document and generate one HL7 message for each. 

In this case the looping would be done in a business process (BPL), and you would call the transformation once for each outbound HL7 message.

 

Hi Joseph,

I developed something like this for a POC last year. It includes wizards to generate Business Services and Business Operations and related message objects based on a source query or stored procedure.

It's not currently in a state where I can share it, but I'm planning to eventually clean it up and post it on Open Exchange. I'll let you know when I do.

What about setting "Reply Code Actions" to "E=D" and enabling "Alert on Error"?

From the reply code actions help text:
"D - Disable the Process, log an error and restore the original incoming message to the front of the Process's queue."

For current versions, the approach I've seen customers use is to create a business operation using the HL7 or XML outbound file adapter. In Message Viewer you can then "resend" the messages you want to the new business operation.

I'm happy to say that we've added a way to download multiple messages directly from Message Viewer. This hasn't been released yet but will be soon. For more details on this and other upcoming features, have a look at this presentation.

Hi Guillaume,

Here's some rough code showing how to use executeParametersBatch. I put this together from a few other working examples I had but I haven't tested this actual code and it may have bugs.

As always, this is provided as sample code only and is not meant for production use :)

This won't help you in the short term, but upcoming versions will include a nice feature to export messages from the message search page. For more details, have a look at this presentation from this year's InterSystems Global Summit.

For the short term, most people use the suggestion from @Julian Matthews of adding a new file out business operation and resending the messages to it.
