How to filter and process different message types?

[tintinn]

How do I go about configuring an inbound channel (LLP listener) to process different type of messages ?

Suppose my channel at LLP port 8080 listens to various type of ADT messages. I'd like to process each type of messages differently depending on the event code. How do I go about doing it ?

As a novice, my plan is that i would create a filter that recognize the ADT event type, and use Destination to resend the message to various Mirth channels (eg A01, A04, A13 etc) i created in order to handle the different message types. Doing it this way ensures that I can create customized transformers, database destinations for the different message types.

Is there a better way of doing this ?

Yes, there is a better way.

All you need is a single channel with all of your destinations, set in Router mode.

You can define a filter on each destination that checks the message type:

var messageType = msg['MSH']['MSH.9']['MSG.1'].text() + msg['MSH']['MSH.9']['MSG.2'].text();
if (messageType == "ADTA04"){
     return true;
}else{
     return false;
}

The destination will only be processed if the message Type matches (this is for HL7 v.2.3 or greater - the mapping is a bit different for 2.2 and 2.1). You can define a seperate transformer and database destination for each "destination" in Mirth. It will only be run if the filter returns true.

thanks.

i wasn't aware that each destinations have separate filters and transformers. *doh*
