Shells can be single instance (one shell can be created for the shell type), or multiple instance (many shells can be created for the type). Single instance shells are represented in Primavera Unifier as a tab, at the same level as the Home tab. Multiple instance shells allow you to create more than one instance of a shell. For example, your top level shell might be called Europe, and is a single instance shell. This shell is represented as a tab. Under this shell, you could use multiple instance shell types to create instances of countries, such as Holland, France, and Hungary. There are templates for shells, just as there are templates for projects. The Shell Manager enables you to import and manage shells and sub-shells for users.
To access the various groups of shells, click the tab with the single instance shell name. The shell landing page displays and the sub-shells are list in the shell log in the lower area of the landing page.
Shell types are characterized by:
| • | A unique system ID |
| • | Single or multiple instance |
| • | Generic or WBS cost code |
Shell instances are copies of shell types, and have these characteristics:
| • | An instance of a shell type must exist before the shell type is viewable in User Mode |
| • | Shell type single can be a root node or a tab |
| • | Shell type multiple populate levels in a hierarchy Shells and the Cost Managers |
