I had this exact issue last week, and this is how I got around it. For clarity, I wanted to pass the Dynamic Object from a process to an operation.

I created my dynamic object within the Process, and then used the %ToJSON Method to put the JSON within a GlobalBinaryStream (which can be passed through the request).

In the Operation, I then use the %FromJSON Method of DynamicAbstractObject to then have the Dynamic Object within the operation.

I have to say, the documentation is very detailed with regards to mirroring. Here is a link.

Could you generate a message to your ens.alert (or equivalent) from the BO, and then immediately call ##class(Ens.Director).EnableConfigItem to disable the business process?

Hi Andrew.

I don't think the operation to a downstream system would be the appropriate place for adjusting the HL7 content.

Using Transforms within a router will be the best approach for this, and while it might seem a little cumbersome creating a transform per message type you should be able to remove some of the leg work by using sub-transforms.

For example; if you were looking to adjust the datestamp used in an admission date within a PV1, rather than complete the desired transform work in every message transform that contains a PV1, you create a sub-transform for the PV1 segment once and then reference this in your transform for each message type. If you then have additional changes required to the PV1 which is message specific (say, a change for an A01 but not an A02) you can then make this change in the message specific transformation.

As far as transforming datetime in HL7, I have faced my share of faff when it comes to this with suppliers. The best approach from within the transforms is to use the built in ensemble utility function "ConvertDateTime" listed here. 

What type of business service are you using? If you are using a single job on the inbound, I guess you're hitting a limit on how fast the adapter can work on handling each message (in your case, you're getting around 15ms per message)

You could look at increasing the pool size and jobs per connection if you're not worried about the order in which the messages are received into your process.

Hi Alexandr.

If you are looking to run a task at specific times, you could create a new task which extends %SYS.Task.Definition to then be selectable as an option from the task manager.

For example, I have a folder which I need to periodically delete files older than x days.

To achieve this, I have a class that looks like this:

Class DEV.Schedule.Purge Extends %SYS.Task.Definition
{

Parameter TaskName = "Purge Sent Folder";

Property Directory As %String;

Property Daystokeep As %Integer(VALUELIST = ",5,10,15,20,25,30") [ InitialExpression = "30" ];

Method OnTask() As %Status
{

Set tsc = ..PurgeSentFolder(..Directory,..Daystokeep,"txt")
Quit tsc
}

Method PurgeSentFolder(Directory As %String, DaysToKeep As %Integer, Extention As %String) As %Status
{
// Calculate the oldest date to keep files on or after
set BeforeThisDate = $zdt($h-DaysToKeep_",0",3)

// Gather the list of files in the specified directory
set rs=##class(%ResultSet).%New("%File:FileSet")
Set ext = "*."_Extention
do rs.Execute(Directory,ext,"DateModified")

// Step through the files in DateModified order
while rs.Next() {
set DateModified=rs.Get("DateModified")
if BeforeThisDate]DateModified {
// Delete the file
set Name=rs.Get("Name")
do ##class(%File).Delete(Name)
}
// Stop when we get to files with last modified dates on or after our delete date
if DateModified]BeforeThisDate 
set tSC = 1
}
quit tSC
}

}

Then I created a new task in the scheduler, selected the namespace where the new class exists, and then filled in the properties and times I want the task to run.

Hi Stephen.

Are you able to select the specific queue from the Queues page and press the abort all button, or does it return an error?

Yes, a new schema can do this along with a transformation.

If you have an existing schema, probably best to clone it and then edit the clone to speed things up.

So I found that it is possible to save single messages using the "HL7 V2.x Message Viewer" which might not be suitable for you if you're looking to export loads of messages.

One option could be to add a new HL7 file out operation, search for your desired messages from the Router you wish to "export" from and then resend them to a new target which can be selected from the Resend messages page.
