Using Iguana 4.0 (or a later version) and Chameleon, you can split an incoming HL7 message into multiple output messages using scripted transformation.

In this tutorial, an incoming ADT^A17 (Swap Patients) message is transformed into multiple ADT^A02 (Transfer a Patient) messages. This requires you to do the following:

• Use Chameleon to create a VMD file that contains a Python transformation script. This script writes transformed ADT^A02 messages to an output file directory.

• Create a channel in Iguana that uses this VMD file to split incoming messages.

• Create another channel to process the split messages.

The following sections describe these steps.
