A selected change package's properties can be viewed in the Change Perspective, but when the change package is re-opened in the View Compare/Merge session, its properties can be edited with the VCM Session Properties dialog box. This dialog box servers several purposes. It allows you not only to view or change the properties of the change package, but it also allows you to commit the changes if the session was new, add or change the change session labels, and add a comment for the committed revision.
This procedure assumes you have already saved one or more change packages that will be visible in Change Perspective of the target view in which it resides.
