To organize your work with tracker artifacts, you can make an artifact a "child" or a
"parent" of another artifact.
- A child artifact can have only one parent.
- A parent artifact can have any number of children.
- A parent artifact cannot be closed if a child is open.
Note: "Open" and "Closed," in this context, refers to a type of status, not the status
itself. A tracker administrator can specify a group of statuses, such as "Deferred,"
"Fixed," or "Rejected," as equivalent to "Closed," while "In progress" and "Under
consideration" might be specified as "Open" statuses. For example, when you look at
the artifact summaries at the top of any tracker list page, you are seeing a summary
of the status type, not the status, of the artifacts.
