Placer Order Management [LAB-1] - the Order Placer (EPR, order comms, GP system) sends a new order to the Order Filler (LIMS), and may later cancel it. The Order Filler accepts or rejects it.

The FHIR equivalent is the Laboratory Order (O21)
message: a Bundle Message whose
MessageHeader has eventCoding v2-0003 O21
and focus the Laboratory Order(s). ORL^O22
is a FHIR response message (MessageHeader.response). Order control (ORC-1) maps to
ServiceRequest.status - see v2-0119-to-request-status.
A GP requests a full blood count.
