State Model
State model allows you to configure workflow control according to the status of an object, such as a service request or a product defect. A state represents the status of an object, such as Open, Closed, or Pending. The state represents where the object is in the lifetime of the object. The state can determine whether the user can or cannot modify the data of that object. For example, a service request that is in a Closed state might be considered frozen and the user cannot modify the object.
A state transition defines how the user can modify an object from one state to the next. For example, state model can allow a user to modify the state for a service request from Closed to Open, from Open to Pending, but not directly from Closed to Pending. Modifying a service request from Closed to Open or Open to Pending represents a state transition. For more information, see the content about State Model in Siebel Applications Administration Guide.
