Lorenz - June 26 th 2005 / 18 CONFIDENTIAL Status and Action Management in a Nutshell Basic Elements Actions represent the process steps to be performed on a business object  Actions are service operations within the Enterprise Services Respository (ESR) that implement business logic  Performing actions change status depending on the result Status describes the progress of the business object life cycle  Driven by actions  Status values desribe the progress of the associated actions Constraints describe which actions are allowed to be performed when specific status are reached Meaning Status and action management is a constraint-based model which governs the life cycle of a business object (node) by defining constraints between status and actions Action

In addition, Compound Services offered by the Business Objects and by AP for usage in Composite Applications are shown. No other BO interactions, calls or services are shown. §5 For each Process Component Interaction cross DU or B2B a Process Component Interaction Model is required. §6 Process Component Interaction Model entities are represented in the Enterprise Services Repository. §7 Models and Enterprise Services Repository have to be in sync, Implementation follows modeling. §8 Each key model entity has an owner.
