A Business Process Diagram modeled with Camunda Modeler or Signavio. The process flow is in a Lane (“LANE # 1”), whereby at least one Activity (“Activity”) has a Boundary Event (“ErrorEvent”). This diagram is to be imported into the Enterprise Architect.
BPMN modeling tools such as Camunda Modeler or Signavio reference Boundary Events as an element contained in a lane (see below, the line marked with red), although basically only the respective activity element is in this Lane and the Boundary Event element is a part (a subelement) this Activity element is.
The BPMN standard does not provide a clear description of how a Boundary Event element should be mapped to Lane affiliation.
