Unable to set WoNumber field while POSTing /crmRestApi/resources/

I do a REST POST of /crmRestApi/resources/ with the foll payload

"Title": "WO5 created by REST",
"OwnerTypeCd": "ORA_SVC_CUSTOMER",
"AccountPartyId": "30000000xxxxxx",
  "FieldServiceResourceId": "30000000xxxxxx",
  "WoIntegrationCd": "ORA_WO_INT_SVC",
  "IBAssetId": "10000000xxxxx",
  "WoNumber": "xxxxxx"

I get a 400 Bad request response with the following payload

  "title": "Bad Request",
  "status": "400",
  "o:errorDetails": [
  "detail": "Reference Number cannot be updated.",
  "o:errorCode": "27008",
  "o:errorPath": "/WoNumber"

WoNumber is the PUID and I should be able to set it to a unique value from an external system. This is how most entities in CRM work, not sure why this is behaving differently. This is a product bug.

Doc Ref:
WoNumber: string
Title: Reference Number
Read Only: true
Maximum Length: 30
The alternate unique identifier of the work order. This value is system-generated, and is configured in the work order profile options SVC_WO_NUMBER PREFIX and SVC_WO_NUMBER_FORMAT. The default configuration is WO0000000000.

Business Use Case: Customer uses ServiceMax as an external Field Service system and imports WorkOrders and Charges aka Debriefs (Service Logistics entity) from that system. They need to set the WoNumber as the ServiceMax Work Order Number. Now, I am having to create a custom field, make it indexable and searchable to store this value. But even then, I cannot easily search for the WO from the landing page using the Find box.

400 Bad Request
