Architecting and designing
  
Activity based costing
When you update Activity Based Costing (ABC) for each Elementary Business Process, System Architect multiplies the cost drivers and the frequencies which you have specified. The result is a read-only figure in the Modify Definition [Elem. Business Proc.] dialog, labeled Total Cost.
To update ABC, you must assign a cost driver to an Elementary Business Process, execute the update, and view the Total Cost in the Elementary Business Process definition.
