BPMN21 — Contradiction - can or cannot show Data Object multiple times on a diagram

  • Key: BPMN21-388
  • Legacy Issue Number: 19771

  • Summary:

    p.206 states:

    Visual representations of Data Objects
    Data Object can appear multiple times in a Process diagram. Each of these appearances references the same Data Object instance. Multiple occurrences of a Data Object in a diagram are allowed to simplify diagram connections.

    p.368 states:

    Multiple depictions of a specific BPMN element in a single diagram is NOT allowed, except for Participants in a choreography (i.e., Participant Bands). For example, it is not allowed to depict a Task twice in the same diagram, but it is allowed to depict the same Task in two different diagrams.

    This seems like a contradiction. Only one of the above should be true.
