  Check Dependencies: If the activities are dependent on one another, ensure that the dependencies are correctly defined and that they do not lead to synchronization issues.
  Use the Alert Monitor: Utilize the Alert Monitor in APO to identify and analyze the specific activities causing the synchronization violation. This can provide insights into which activities need to be adjusted.
