What happens if one of the activities is skipped
If one or more of the stage activities was not completed, and the opportunity was moved to the next stage with the workflow bar, then the activity will be canceled automatically. The system will generate a new list of activities corresponding to the current opportunity stage.
Note
Automatically and manually created uncompleted tasks will not be canceled when moving to the next stage. Uncompleted tasks do not affect transition to next stages.
