Using BP to create multiple messages from a single HL7

Hi all.

I'm currently working with a system needing results from a lab system, and they can only accept a single OBR per R01 message.

The R01s from the source have multiple OBRs, so I need to be able to send a message per OBR.

I found a similar post where the example was using a BPL, however there's some additional trickery processing that I already have working within an ObjectScript Business Process and would like to avoid trying to recreate in a BPL.

Any sample code will be greatly received
