  Review Resource Capacity: Check the capacity settings for the resource in question. Ensure that the capacity is set correctly and that it reflects the actual available capacity.

  Check for Overlaps: Ensure that there are no overlapping activities that could be causing the capacity to be exceeded. If there are, adjust the scheduling to avoid overlaps.
  
  
  Capacity Planning Settings: Review the settings in the Capacity Planning area to ensure that they are configured correctly. This includes checking the bucket size and the planning horizon.
  
  
  Use Capacity Evaluation Tools: Utilize the capacity evaluation tools available in SAP APO to analyze the resource utilization and identify potential issues.
