Automatic activities are steps in a workflow that are executed without any human intervention. When a step in a business process needs to be executed by the system, the workflow that represents that business process requires an automatic activity.
An automatic activity invokes a method of any BPO or entity method. Its definition specifies the fully qualified name of the method to call, which parameters to pass to it, and what results to retrieve from it. Input mappings specify which workflow data should be passed as parameters to the business process. Output mappings are used to map data calculated, retrieved, and/or modified by the method back into the workflow data. It can then be used anywhere in the remainder of the process, e.g., the data can be used in the following activities or transitions.
The metadata associated with automatic activities is described in the Automatic chapter of the Cúram Workflow Reference Guide.
