Users who are administrators or editors of a project can
create subprojects in the User interface.
About this task
A subproject is derived from an existing project (parent
project) but is more specific in scope. For example, you can create
a parent project for SystemA and subprojects for different releases
of SystemA. Subprojects inherit the contents of the parent project,
but the contents must be further refined by adding additional criteria.
Likewise, administrators and editors are implicitly inherited. A subproject
does not show inherited administrators and editors unless someone
has explicitly added them.
