A repository workspace can contain many active change sets
but only one current change set. By default, the current change set
accumulates all changes that you check in.
About this task
If you have more than one active change set in a workspace,
one of them is identified as the current change set (the one in which
all check-ins accumulate by default). If you want, you can specify

resolve a defect immediately and deliver that change to the team without
affecting another change set that you are working on.
Note: A file or folder in a component cannot be part of
more than one active change set. When a file or folder is included
in an active change set, all changes to it become part of that change
set whether or not the change set is current, and changes to that
file or folder cannot be explicitly checked in to a new change set
