• What is the cause and solution for SAP error message /SAPAPO/CDPSOPT822 - Optimization run ended with no solution ?

  The SAP error message /SAPAPO/CDPSOPT822 Optimization run ended with no solution typically occurs in the context of SAP Advanced Planning and Optimization (APO) when an optimization run fails to find a feasible solution for the given planning scenario. This can happen for various reasons, and understanding the cause is crucial for resolving the issue.
  Causes:
  
  
  Infeasible Constraints: The optimization model may have constraints that are too strict or conflicting, making it impossible to find a solution. This can include capacity constraints, demand constraints, or other planning parameters that do not align.
  
  
  Data Issues: Missing or incorrect master data (like product, location, or resource data) can lead to infeasibility. For example, if a resource is defined with zero capacity, the optimizer cannot allocate any production.
  
  
  Planning Parameters: Incorrectly set planning parameters, such as lead times, lot sizes, or safety stock levels, can also lead to infeasibility.
  
  
  Demand and Supply Mismatch: If the demand exceeds the available supply or if there are no available products to meet the demand, the optimizer will not be able to find a solution.
  
  
  Optimization Settings: The settings used for the optimization run may not be appropriate for the current planning scenario.
  
  
  Solutions:
  
  
  Review Constraints: Check the constraints defined in the planning model. Ensure that they are realistic and do not conflict with each other.
  
  
  Validate Master Data: Ensure that all relevant master data is complete and accurate. This includes checking product availability, resource capacities, and any other relevant data.
  
  
  Adjust Planning Parameters: Review and adjust planning parameters to ensure they are set correctly. This may involve modifying lead times, lot sizes, or safety stock levels.
  
  
  Analyze Demand and Supply: Check the demand and supply data to ensure they are aligned. If demand exceeds supply, consider adjusting forecasts or increasing supply.
  
  
  Run Diagnostics: Use the diagnostic tools available in SAP APO to analyze the optimization run. This can help identify specific issues that led to the failure.
  
  
  Test with Simplified Scenarios: If possible, run the optimization with a simplified version of the data to isolate the issue. Gradually reintroduce complexity to identify the specific cause of infeasibility.
  
  
  Consult Documentation: Review SAP documentation and notes related to the optimization run for any known issues or additional troubleshooting steps.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /SAPAPO/CDPSOPT for running optimization and /SAPAPO/CDPSOPTLOG for viewing logs.
  SAP Notes: Check for any SAP Notes that may address known issues related to optimization runs.
  Community Forums: Engage with SAP community forums or support channels for additional insights and shared experiences from other users facing similar issues.
  
  By systematically addressing these areas, you should be able to identify the root cause of the error and implement a solution to successfully complete the optimization run.
