Mapping BPMN 2.0 constructs to IBM Business Automation Workflow

Edit online

You can import elements from the IBM WebSphere® Business Modeler into IBM Business Automation Workflow, using the Business Process Model and Notation (BPMN) Version 2.0 file format.

The following table shows the mapping between elements in the Business Process Model and Notation (BPMN) Version 2.0 file format and their equivalent IBM Business Automation Workflow objects or properties, after import. If an element is not included in the table, the element is not imported. The main library elements are in boldface type. The elements that are not in boldface type and are listed under a main library element, are subordinate elements within them.
BPMN construct IBM Business Automation Workflow element Comments
Item definition Business object  
Message that does not refer to an item definition Business object - without a structure  
Resource Team Before version 8.5 the team element was known as participant group.
Global task Service flow or Advanced Integration service Element selection depends on your choice in the procedure described in Moving business processes from WebSphere Business Modeler to Process Designer or Importing BPMN models.
Global user task Client-side human service  
Global rule task Decision service  
Interface - with or without a backing WSDL Service flow or Advanced Integration service A service is generated for each operation in the interface. Element selection depends on your choice in the procedure described in Moving business processes from WebSphere Business Modeler to Process Designer or Importing BPMN models.
Process Business process definition (in CF2017.12 and earlier)

Process (in CF2018.03 and later)
  
Task Activity The following rules apply:
  • If the task has performers, the activity has a user task implementation and has a reference to a client-side human service.
  • If the task has no performers, the activity has both a system task implementation and a reference to a service flow.
  • If an incoming service is, for example, a web service that contains data to set up a binding, it is reflected in the business service.
Human task User task with a reference to a client-side human service  
Business rules task Decision task with a reference to a service flow  
Service task - To an operation with or without a backing WSDL Activity with a system task implementation and a reference to a service flow  
Receive task Intermediate message event  
Script task Activity with a JavaScript implementation  
All other task types Activity  
Subprocess Activity with a subprocess type Only a single none start event is allowed. Other start event types are collapsed into the single none start event.
Event subprocess Activity with an event subprocess type Only a single error, timer, or message start event is allowed. If there is more than one, only the first is used. Other start event types are converted to an error start event.
Call activity with a reference to a process Activity The activity has a reference to a business process definition.
Call activity with a reference to a global task Activity with a service (task) implementation and a reference to a service flow The activity has a reference to a service.
Exclusive gateway Exclusive gateway  
Inclusive gateway Inclusive gateway  
Parallel gateway Parallel gateway  
Event-based gateway Activity with message boundary events The message catch events that followed the event-based gateway are converted to message boundary events attached to the activity.
None start event Start event Only a single none start event is allowed. If there is more than one, only one will be created.
Message start event Message start event  
Timer start event Timer start event  
Error start event Error start event
