User Story (Required on creation):

I want to keep track of the hierarchy in which an external task runs, in order to display it to my users. If a link points to the parent process, with the feature of CAM-13197 I can build the entire hiearchy of process instances based on external task notifications (e.g. having listeners on the start event of every process).

Functional Requirements (Required before implementation):

• In the Java API, there is a getter to retrieve the parent process instance id
• This is also exposed in the REST API and the external task clients

Technical Requirements (Required before implementation):

Limitations of Scope (Optional):
