Associating events with data objects in BPMN diagrams

Events in BPMN diagrams can be associated with a data objects, data stores, data inputs, or data outputs, depending on the type of event that occurs. End and throw events are associated with data inputs, data stores or data objects, and start and catch events are associated with data outputs, data stores or data objects.

About this task

Before you can associate a data object, input, or output with an event, the event must have a signal trigger or message defined. You must have an event and a data object, input, or output created in the diagram editor.

Procedure

  1. In the Palette, click the Connector icon.
  2. In the diagram editor, click the element to reference and then drag the cursor to the referenced element. If there are multiple triggers, click a trigger in the dialog box. You can drag to an empty space in the diagram editor to create a new element to be referenced.

Example

In the following example, a start event is associated with DataObject1 and DataOutput1. DataInput1 is associated with an intermediate throw event. In each case, the elements have matching item definitions.
