Once you have modeled your business process on the BPMN canvas, you have to add the necessary execution parts to this process to bring it to life. The execution canvas is the place where you make your model executable.
You need to perform two steps to implement executional parts to your model:
- Provide all necessary data types and operations for the implementation of your process. These types and operations reside in the Service panel of the BPMN editor.
- You can use the Base Types that are provided with the Designer.
- You can create other necessary types yourself in the Implementation section.
Refer to Modeling Data Mapping for further information. - You can import a library that provides additional types and operations.
Refer to Designer Administration > Libraries for further information.
- In the second step, select data types and operations from the Service panel, and add them to your process at the right places.
- How this is done will be explained in this chapter.
The Execution Canvas
The execution canvas is displayed below the BPMN canvas. It is shown as soon as you click on one of the BPMN elements:
The content of the execution canvas depends on the selected object on the BPMN canvas - three different views are possible:
| Selected BPMN Elements | Canvas Content | Execution Canvas View |
|---|---|---|

Execution Canvas Contents
| Section | Description |
|---|---|
UML activity diagram | The execution is modeled as a UML activity diagram. Every execution canvas contains an empty diagram with start and end node. |
Persisted | Variables created in section Persisted are usable in all executions of the BPMN model. |
| Local | Variables created in section Local are only available for use within the current execution. |
| Message | Section Message is shown for all BPM elements that need to process an incoming message. As per default, the incoming message has type any. To gain access to the data used in your process, you have to apply the correct type from a customized library. |
| Return | Only for outgoing relations of Exclusive Gateways Section Return is displayed, containing the unchangeable object return of type boolean. |
Customizing the Canvas
You have several options to adjust the canvas. When you open the canvas for the first time, the default view is displayed:
