For cost management in a shell, you can choose either to use Primavera Unifier’s Standard Cost Manager, or to create your own Generic Cost Manager in uDesigner. The generic cost manager specifically supports costing for shells that manage business information that is not of a fixed duration or cost, such as ongoing leases, building maintenance, or landscape care.
In the hierarchy of your shells, one shell might use the Standard Cost Manager while another might use a generic cost manager. There is, however, a limitation: Primavera Unifier will roll up information only from shells that use a generic cost manager; it will skip shells using the Standard Cost Manager.
Note: There are some limitations to a generic cost manager. For a comparison of the generic and Standard Cost Managers, see Generic Cost Manager Overview.
Tip: Although roll-ups in a shell will omit information from the Standard Cost Manager, you can roll up that information to the Program level, and run a report to capture it.
