DTS allows you to add or remove objects for change tracking in the consumption process. This topic describes how to modify objects for change tracking.


  • After you add an object, the change tracking task pulls the incremental data of the new object from the time when the modification takes effect.
  • After you remove an object, if the change tracking client can tracks data changes of the removed object, you need to filter the object in the change tracking client.
