Salesforce -按id编辑多态查找

Question

我需要更新多态查找字段的id。我使用的是批量API v48.0。如果我将数据上载到作业(例如，更新事件对象)

id,Lead:Who.Id
00U5f000008eventId,00Q5f000003ISwhoId

则事件未更新，API返回作业状态。

{
  "id": "7505f000002pnjobId",
  "operation": "upsert",
  "object": "Event",
  "createdById": "0055f0000032userId",
  "createdDate": "2021-12-08T11:06:29.000+0000",
  "systemModstamp": "2021-12-08T11:06:51.000+0000",
  "state": "JobComplete",
  "externalIdFieldName": "Id",
  "concurrencyMode": "Parallel",
  "contentType": "CSV",
  "apiVersion": 48.0,
  "jobType": "V2Ingest",
  "lineEnding": "LF",
  "columnDelimiter": "COMMA",
  "numberRecordsProcessed": 1,
  "numberRecordsFailed": 1,
  "retries": 0,
  "totalProcessingTime": 62,
  "apiActiveProcessingTime": 3,
  "apexProcessingTime": 0
}

如果我填写电子邮件而不是身份证

id,Lead:Who.Email
00U5f000008eventId,test@mail.com

然后成功地更新事件。

如何通过对象id更新多态查找值？

Answer 1

在更新查找字段本身的值时，不需要使用多态关系语法。只需引用该字段的名称，WhoId

Id,WhoId
