Can I use a (business process) lane in a sequence diagram in enterprise architect?

In Enterprise Architect I have represented one of our systems as a lane on a BPMN diagram. I would like to reuse that system in various UML sequence diagrams, however when I add the system to a SD it shows as a lane rather than a Lifeline. Any idea how to approach that?

Solution

  • Assuming that you talk about BPMN, the specs say on p. 111

    A Pool acts as the container for the Sequence Flows

    Lanes are just sub-partitions of pools.

    So, it is not an object that has behavior but only surrounds a couple of behaviors.

    You would need to create single SDs showing the behavior of actitivities inside a lane. Question is: why use SDs which are meant for technical description if you already described the communication on a business process level?
