Question

How do I create a duplicate of my PV1 segment, but name it PD1?

Answer 1

In order to add a segment after the originating segment, use message.addChildAfter(). Here is an example of how to use this:

message.addChildAfter('PV1', 'PD1', 'PD1' + StringUtils.substringAfter(message.getNode('PV1'), 'PV1'));
