Rentain,
Your message is actually an HRL and not really a VRL. What this means is that it’s a set of different VRL’s not just a single VRL.
HL7 is an HRL. Each message is a set of VRL’s.
You can use the VRL and HRL tool to build this message structure. Use the VRL tool to build the segments. Then put them together using the HRL tool.
Cheers,
