As part of our Usecase we receive the Order ID from HL7 ORM messages in our application, using this Order ID we wanted to fetch the ServiceRequest R4 FHIR resource, but currently as per Cerner Millennium documentation ServiceRequest FHIR resource only have system id to fetch the data and they currently does not have business identifier.
What we receive from HL7 ORM Orders are the Business Identifier and not system ID, for other FHIR resources like Encounter, Patient etc, Cerner has both System ID and Business Identifier, but the business identifier is missing in ServiceRequest resource.
Please suggest a way to link the HL7 ORM orders & ServiceRequest FHIR Resource retrieved from Cerner Millennium ?
Captured the list of available data attributes from Cerner Millennium documentation below. If you see here it only has ServiceRequest id without any business identifier field.
