如何通过API更新PowerApps Dataflow的所有者？

错误尝试及报错 #

尝试1：直接PATCH更新ownerid #

PATCH <ORG-DOMAIN>/api/data/v9.2/msdyn_dataflows(<DATAFLOW-ID>)
Body = {"ownerid@odata.bind" = "/systemusers(<USER-ID>)"}
Headers = {"Authorization" = "Bearer <TOKEN>", "Content-Type" = "application/json"}

报错：

"error":{"code":"0x80040265","message":"This operation is not supported."}

尝试2：使用$ref关联所有者 #

POST <ORG-DOMAIN>/api/data/v9.2/msdyn_dataflows(<DATAFLOW-ID>)/owner_msdyn_dataflow/$ref
Body = {"@odata.id" = "<ORG-DOMAIN>/api/data/v9.2/systemusers(<USER-ID>)"} 
Headers = {"Authorization" = "Bearer <TOKEN>", "Content-Type" = "application/json"}

报错：

"error":{"code":"0x80060888","message":"The URI segment '$ref' is invalid after the segment 'owner_msdyn_dataflow'."}}

正确的API调用方法 #

msdyn_dataflow实体的所有者变更需要使用Dataverse的Assign专用操作，具体请求如下：

POST <ORG-DOMAIN>/api/data/v9.2/Assign
Headers:
Authorization: Bearer <TOKEN>
Content-Type: application/json

请求Body：

{
  "Target": {
    "entitytype": "msdyn_dataflow",
    "id": "<DATAFLOW-ID>"
  },
  "Assignee": {
    "entitytype": "systemuser",
    "id": "<USER-ID>"
  }
}

说明 #

Dataverse中部分实体（如数据流、仪表板等）的所有权转移不支持直接字段更新或普通关联操作，必须通过Assign消息来完成，这是平台规定的标准所有权分配流程。
