• What is the cause and solution for SAP error message /SAPAPO/ND324 - Admissible, non-optimal solution found (due to error) ?

  The SAP error message /SAPAPO/ND324 Admissible, non-optimal solution found (due to error) typically occurs in the context of SAP Advanced Planning and Optimization (APO) when the system is unable to find an optimal solution for a planning problem due to certain constraints or errors in the data or configuration.
  Cause:
  
  Data Issues: There may be inconsistencies or errors in the master data, such as incorrect or missing information in the product master, location master, or resource master.
  Constraints: The planning run may be encountering constraints that prevent it from finding an optimal solution. This could include capacity constraints, transportation constraints, or other planning parameters that are not set correctly.
  Configuration Errors: Incorrect settings in the planning area, planning book, or other configuration elements can lead to this error.
  Solver Limitations: The optimization solver may be unable to find a feasible solution due to the complexity of the problem or limitations in the algorithm used.
  
  Solution:
  
  Check Master Data: Review the relevant master data for the products, locations, and resources involved in the planning run. Ensure that all necessary data is complete and accurate.
  Review Constraints: Analyze the constraints defined in the planning area. Check if any constraints are overly restrictive and consider adjusting them if necessary.
  Configuration Review: Verify the configuration settings in the planning area and planning book. Ensure that they are set up correctly and align with the business requirements.
  Run Diagnostics: Use the SAP APO diagnostic tools to identify any underlying issues. This may include checking logs or running specific reports to gather more information about the planning run.
  Adjust Planning Parameters: If applicable, consider adjusting the planning parameters or settings to allow for more flexibility in the optimization process.
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes or updates that may address this specific error message or provide additional guidance.
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like /SAPAPO/SDP94 (for planning book) or /SAPAPO/SDP93 (for planning area) to review and adjust settings.
  SAP Help Documentation: Refer to the official SAP documentation for APO for detailed information on planning areas, constraints, and optimization settings.
  Community Forums: Engage with the SAP community forums or user groups to see if others have encountered similar issues and what solutions they have found.
  
  If the problem persists after following these steps, it may be beneficial to involve your SAP Basis or APO support team for further investigation.
