Smart SAP Assistant

• What is the cause and solution for SAP error message /SAPAPO/PP_OPTIMIZER831 - Optimizer run failed without result. ?

  The SAP error message /SAPAPO/PP_OPTIMIZER831 indicates that an optimizer run in SAP Advanced Planning and Optimization (APO) has failed without producing any results. This can occur for various reasons, and understanding the cause is crucial for resolving the issue. Below are some common causes, potential solutions, and related information:
  Causes:
  
  Data Issues: Missing or incorrect master data (e.g., materials, resources, or production versions) can lead to the optimizer failing to generate a feasible plan.
  Configuration Problems: Incorrect settings in the optimizer configuration, such as planning parameters or heuristics, can cause the run to fail.
  Resource Constraints: If there are too many constraints on resources (e.g., capacity, availability), the optimizer may not find a feasible solution.
  Planning Area Issues: Problems with the planning area, such as incorrect key figures or data inconsistencies, can lead to failures.
  Locking Issues: If the data being accessed is locked by another process, it may prevent the optimizer from running successfully.
  Insufficient Data: If there is not enough data to generate a plan (e.g., no demand or supply data), the optimizer may not produce results.
  
  Solutions:
  
  Check Master Data: Verify that all necessary master data is complete and accurate. Ensure that materials, resources, and production versions are correctly defined.
  Review Configuration: Check the optimizer configuration settings. Ensure that the planning parameters and heuristics are set correctly for your planning scenario.
  Analyze Resource Constraints: Review the constraints applied to resources. Consider relaxing some constraints to allow the optimizer to find a feasible solution.
  Validate Planning Area: Ensure that the planning area is correctly set up and that key figures are populated with valid data. Check for any inconsistencies in the data.
  Monitor Locks: Use transaction codes like SM12 to check for locks on the data being accessed by the optimizer. If locks are found, resolve them appropriately.
  Data Availability: Ensure that there is sufficient demand and supply data in the system for the optimizer to work with. If necessary, create or adjust the data to provide a basis for planning.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like /SAPAPO/OPTIMIZER to access the optimizer settings and /SAPAPO/MC90 to check the planning area.
  Logs and Traces: Check the optimizer logs for detailed error messages that can provide more context on why the run failed. You can find logs in transaction /SAPAPO/OPTIMIZER or by using the application log (SLG1).
  SAP Notes: Search for relevant SAP Notes in the SAP Support Portal that may address known issues related to the optimizer.
  Documentation: Refer to the SAP APO documentation for detailed information on configuring and troubleshooting the optimizer.
  
  By systematically checking these areas, you should be able to identify the cause of the error and implement a solution to resolve it. If the issue persists, consider reaching out to SAP support for further assistance.
