Before creating the Logical Activities diagram, the  Logical Activities Taxonomy diagram should be created first.

To create an L4 Logical Activities diagram for Operational Activity flows

  1. Create Operational Activity Actions or drop them from the Containment tree directly to the diagram pane.
  2. Connect Operational Activity Actions with Operational Control Flow or Operational Object Flow.
  3. Display the possible Operational Exchanges on Operational Control Flow or Operational Object Flow.
