  Check Planning Parameters: Review the planning parameters and settings in the system to ensure they are configured correctly to prevent overlaps.
  Use Planning Tools: Utilize SAP planning tools and reports to visualize and manage assignments effectively, helping to identify potential conflicts before they occur.
  
  Related Information:
