A new workflow Process Instance row is created for each enactment of a workflow Process Definition.

Example

You define a workflow (Process Definition) to allow correspondence to be sent to customers whenever their payment details change. The workflow contains several activities.

Person John Smith's payment details change due to an increase in rates. This increase raises an event which causes the Workflow Engine to enact your workflow and create a row on this table. All subsequent processing of the workflow for John Smith acts on data which is ultimately tied back to this row.

Person Mary Smith's payment details also change; the Workflow Engine enacts the same workflow as for John, but creates a separate Process Instance.

Technical Notes

Processes may be enacted by:

• an explicit call to the enactment service (i.e. an explicit call that you write in your customized server application);
• the occurrence of a system event which you have configured (using the Admin Application) to start your process; or
• a sub-flow activity in a parent Process Instance.

You can customize the Curam server application to raise new system events which you can then configure to trigger the enactment of your workflow(s).
