Step 2.1: CAT notifies Requester HCP that service request was cancelled
See Step 10 in Primary Flow message flow with changes as below:
| Element | Value |
|---|---|
| MessageHeader.destination.endpoint | Requester HCP EMR endpoint |
| MessageHeader.source.endpoint | CAT RMS endpoint |
| Task.status | "cancelled" |

Step 3: CAT sends service request cancellation to Performer HCP
Same as Step 1 above with changes as below:
| Element | Value |
|---|---|
| MessageHeader.eventCoding | "notify-update-service-request" |
| MessageHeader.destination.endpoint | Performer HCP EMR endpoint |
| MessageHeader.source.endpoint | CAT RMS endpoint |
