• What is the cause and solution for SAP error message /SAPAPO/CDPSOPT831 - Relax-and-Resolve optimizer ended ?

  The SAP error message /SAPAPO/CDPSOPT831 Relax-and-Resolve optimizer ended typically indicates that the optimizer in SAP Advanced Planning and Optimization (APO) has encountered an issue during its execution. This error can arise from various causes, and understanding the context is crucial for troubleshooting.
  Possible Causes:
  
  Data Issues: Incomplete or incorrect master data (e.g., product, location, or resource data) can lead to optimizer failures.
  Configuration Problems: Incorrect settings in the optimizer configuration or planning area can cause the optimizer to fail.
  Resource Constraints: If there are insufficient resources or capacity constraints defined in the system, the optimizer may not be able to find a feasible solution.
  Infeasible Planning Problem: The planning problem may be infeasible due to conflicting constraints or unrealistic demand/supply scenarios.
  Memory Issues: The optimizer may run out of memory if the problem size is too large or if the system is under heavy load.
  
  Solutions:
  
  Check Master Data: Ensure that all relevant master data is complete and accurate. This includes checking product, location, and resource data.
  Review Configuration: Verify the configuration settings for the optimizer and the planning area. Ensure that all necessary parameters are set correctly.
  Analyze Constraints: Review the constraints defined in the planning area. Look for any conflicting constraints that may be causing the infeasibility.
  Run Smaller Scenarios: If the problem size is large, try running the optimizer on a smaller subset of data to see if it completes successfully.
  Monitor System Resources: Check the system's memory and CPU usage during the optimizer run. If necessary, allocate more resources or optimize the system performance.
  Check Logs: Review the optimizer logs for any additional error messages or warnings that can provide more context about the failure.
  Consult SAP Notes: Look for relevant SAP Notes or Knowledge Base Articles (KBAs) that may address known issues related to this error message.
