Create a new version (KIT)
A Product Structure (KIT) may be configured into several versions. Several versions of a structure specification may exist, but only a single version can be valid at any one time. However, every product will keep track of all its versions from the first one to the latest, valid version. The versions may be inspected in the Versions drop-down menu.

In order to modify a structure, a new version must first be created from a copy of version 1.
Click the Copy version icon and a new version 2 is automatically created in Status 1.
This enables the Designer tab. In addition, the ValidFrom date is set to today's date, and the VersionPid is set to the current user's PID. Two new icons are added to the toolbar, one to request approval, and one to delete version 2.
