BPEL 2.0 Model
Enterprise Architect uses BPMN 2.0 as a graphical front-end to capture BPEL 2.0 Process description (as BPEL 2.0 does not have not a standard graphical notation). Enterprise Architect uses the partial mapping specified in the BPMN 2.0 specification to map BPMN 2.0 constructs to BPEL 2.0.

Notes
| · | Generating BPEL 2.0 from a BPMN 2.0 model is supported in the Business and Software Engineering and the Ultimate editions of Enterprise Architect |
| · | Enable the BPMN 2.0 Technology in the MDG Technologies dialog (Extensions | MDG Technologies)
|
BPEL 2.0 Example
| · | The Enterprise Architect Example file ( EAExample.EAP ) has a sample BPMN 2.0 model from which BPEL 2.0 can be generated |
| · | If you have installed Enterprise Architect at the default location, open this file: C:\Program Files\Sparx Systems\EA\EAExample.EAP |
| · | The BPMN 2.0 model Package is in: Project Models | Analysis and Business Modeling | BPEL Example | BPEL 2.0 Model
|
Modeling Restrictions
| · | Every BPEL Process and Sub-Process should start with a Start Event and end with an End Event |
| · | Boundary Start and End Events are not supported
|
| · | Sequence Flow Looping is not supported in both Normal and Exception Paths |
| · | All Sequence Flows should flow downstream and not upstream |
| · | Sub-Process cannot be a Loop node and have boundary Intermediate Events |
| · | Event Sub-Process cannot act as a Loop Node |
| · | Assignments are not supported on: |
| · | Start Events on Event Sub-Process |
| · | Boundary Intermediate Event |
| · | Task and Intermediate Event that immediately follow an XOR Event Gateway
|
| · | Exception Path has to merge back into the Normal Path |
| · | An exception to this rule is boundary Compensation Intermediate Event which should have a BPMN 2.0 Association to a Compensation Activity (that has no incoming or outgoing Sequence Flows) |
| · | Multiple Exception Paths from an Activity must join at the same location in the Normal Path |
| · | An Exception Path should not cross another Exception Path
|
| · | Activities in an Exception Path cannot have boundary Intermediate Events |
| · | Pools are treated as black boxes (that is, they do not expose any details) and hence they cannot contain any child elements or have any incoming/outgoing Sequence Flow connectors
