• What is the cause and solution for SAP error message /SAPAPO/PPO_OPT073 - Step 2: Model consistency checked and solution calculated at &1 on &2 ?

  The SAP error message /SAPAPO/PPO_OPT073 typically indicates an issue related to the consistency of the model in the Advanced Planning and Optimization (APO) module of SAP. This error occurs during the optimization process when the system detects inconsistencies in the planning model or when the solution cannot be calculated due to certain constraints or data issues.
  Cause:
  
  Model Inconsistencies: There may be inconsistencies in the planning model, such as missing or incorrect master data (e.g., materials, resources, or locations).
  Data Issues: Problems with the data used in the optimization process, such as incorrect or incomplete data in the planning books or infoproviders.
  Configuration Issues: Incorrect settings in the APO configuration that affect the optimization process.
  Resource Constraints: Constraints on resources that prevent the optimization algorithm from finding a feasible solution.
  Versioning Issues: If multiple versions of the planning model exist, there may be conflicts or issues with the version being used.
  
  Solution:
  
  Check Master Data: Verify that all relevant master data (materials, resources, locations) is complete and correctly maintained in the system.
  Review Planning Books: Ensure that the planning books and infoproviders used in the optimization process are correctly set up and contain valid data.
  Analyze Configuration: Review the APO configuration settings to ensure they are correctly defined for the optimization process.
  Examine Constraints: Check for any constraints on resources or other elements that may be preventing a feasible solution. Adjust these constraints if necessary.
  Run Consistency Checks: Use the consistency check tools available in APO to identify and resolve any inconsistencies in the model.
  Check Logs: Review the logs generated during the optimization run for any additional error messages or warnings that may provide more context on the issue.
  Consult Documentation: Refer to SAP documentation or notes related to the specific error message for additional troubleshooting steps or known issues.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like /SAPAPO/OPTIMIZE to run the optimization process and check for errors.
  SAP Notes: Check SAP Notes for any known issues or patches related to the error message.
  Support: If the issue persists, consider reaching out to SAP support for assistance, providing them with detailed information about the error and the steps you have taken to resolve it.
