You can modify an existing Change Task to add one or more Affected Objects or Resulting Objects by providing the required attributes and the Changeables OIDs that you want to add as Affected Objects or Resulting Objects, in the request body. The Change Task may or may not have existing Affected Objects or Resulting Objects associated with it. To create and modify Change Tasks, you must have Create and Modify permissions.

The Affected Objects or Resulting Objects that you want to add must exist and you must have Read permission to those. You can add the Affected Objects or Resulting Objects according to the defined association rules.

You can add any of the Changeables such as parts, documents, subtypes of parts, or subtypes of documents as Affected Objects or Resulting Objects.
