  Solution:
  
  
  Adjust Penalty Costs: Review and adjust the penalty costs for safety stock shortfalls in the SNP configuration. Ensure that these costs reflect the true cost of stockouts or shortages.
  
  Navigate to the SNP configuration settings and locate the relevant parameters for penalty costs.
  Increase the penalty costs to a level that is more realistic and reflective of the business impact of stockouts.
  
  
  
  Review Safety Stock Levels: Analyze the safety stock levels set in the planning book. If they are excessively high, consider adjusting them to align with the penalty costs.
  
  Use historical data and demand forecasts to determine appropriate safety stock levels.
  
  
  
  Check Planning Parameters: Review the planning parameters in the SNP settings to ensure they are correctly configured. This includes lead times, service levels, and other relevant parameters that may impact safety stock calculations.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for detailed guidance on configuring penalty costs and safety stock settings.
  
  
  Testing: After making adjustments, run a test planning run to verify that the error is resolved and that the planning results are feasible.
