• What is the cause and solution for SAP error message /SAPAPO/PP_OPTIMIZER818 - Find start solution ?

  The SAP error message /SAPAPO/PP_OPTIMIZER818 with the description "Find start solution" typically occurs in the context of the SAP Advanced Planning and Optimization (APO) module, particularly when using the PP/DS (Production Planning and Detailed Scheduling) optimizer. This error indicates that the optimizer is unable to find a feasible starting solution for the planning run.
  Causes:
  
  Insufficient Data: The planning data may be incomplete or incorrect. This can include missing master data (like resources, products, or production versions) or planning data (like demand or supply).
  Constraints: There may be constraints defined in the planning run that are too strict, making it impossible for the optimizer to find a feasible solution.
  Resource Availability: Resources may not be available for the required time periods, or there may be capacity constraints that prevent scheduling.
  Incorrect Settings: The settings in the optimizer profile or the planning run may not be configured correctly, leading to issues in finding a solution.
  Data Inconsistencies: There may be inconsistencies in the data, such as overlapping production orders or incorrect lead times.
  
  Solutions:
  
  Check Master Data: Ensure that all relevant master data (materials, resources, production versions) is correctly maintained and complete.
  Review Constraints: Analyze the constraints set in the planning run. If they are too strict, consider relaxing them to allow for more flexibility in scheduling.
  Resource Availability: Verify the availability of resources and ensure that they are correctly defined in the system. Check for any maintenance or downtime that may affect capacity.
  Optimizer Profile Settings: Review the settings in the optimizer profile. Ensure that the parameters are set correctly for the specific planning scenario.
  Data Consistency Check: Run consistency checks on the planning data to identify and resolve any inconsistencies or errors.
  Test with Simplified Data: If possible, try running the optimizer with a simplified dataset to see if it can find a solution. This can help isolate the issue.
