Activity detail diagrams show tasks to be performed as part of an activity associated with a particular role. These diagrams also show mandatory input and output work products for each task. Activity detail diagrams are suitable for activities that consist of only child tasks. You can choose to include diagrams created externally by another application or you can create activity detail diagrams internally by using the Diagram editor.
Activity detail diagrams will be generated during publication if you select the Publish activity detail diagrams that have not been created in process editor option when you publish your configuration.
Note: If you want to use generated diagrams make sure that you do not have any saved activity detail diagrams that are out-of-date. Whenever you open an activity detail diagram a diagram is created and saved for you if there is no diagram already. To remove a diagram, open the context menu on the activity detail diagram editor and select Delete Diagram.
Under Window > Preferences... specify the preference Publish or browse activity detail diagrams that have not been created in process editor so these diagrams will be generated when you browse your processes.
You can modify the activity detail diagram that is created for you when you open the activity detail diagram in the diagram editor. Use the palette tools to make your modifications and save your diagram.
