• What is the cause and solution for SAP error message /SAPAPO/RRP_HEUR200 - There has possibly been a low-level code change for the model &1 ?

  The SAP error message /SAPAPO/RRP_HEUR200 typically indicates that there has been a low-level code change in the model you are working with in SAP Advanced Planning and Optimization (APO). This error can occur during the execution of heuristics or planning runs when the system detects inconsistencies or changes in the underlying data model that may affect the planning process.
  Cause:
  
  Model Changes: The error often arises when there have been changes to the data model, such as changes in master data, planning parameters, or configuration settings that are not compatible with the current planning run.
  Transport Requests: If changes were transported from a development or quality system to the production system, it may lead to inconsistencies if the transport was not executed properly or if there are dependencies that were not included.
  Data Inconsistencies: There may be inconsistencies in the data that the heuristic is trying to process, such as missing or incorrect master data.
  
  Solution:
  
  Check for Recent Changes: Review any recent changes made to the model, including master data, planning parameters, or configuration settings. Ensure that all necessary changes have been properly transported and activated.
  Consistency Check: Run consistency checks on the master data and planning data to identify any discrepancies. You can use transaction codes like /SAPAPO/MDP for master data checks.
  Re-run the Heuristic: After addressing any inconsistencies or issues, try re-running the heuristic or planning run to see if the error persists.
  Review Logs: Check the application logs for more detailed error messages or warnings that may provide additional context about the issue.
  Consult Documentation: Refer to SAP documentation or notes related to the specific heuristic you are using to see if there are any known issues or additional steps required after model changes.
  Contact SAP Support: If the issue persists and you cannot identify the cause, consider reaching out to SAP support for assistance. Provide them with detailed information about the error, including the context in which it occurred.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in SAP APO, such as /SAPAPO/RRP for planning and heuristics.
  SAP Notes: Search for SAP Notes related to the specific heuristic or error message for any patches or updates that may address the issue.
  Documentation: Review the SAP APO documentation for best practices on managing model changes and ensuring data consistency.
  
  By following these steps, you should be able to identify and resolve the issue related to the /SAPAPO/RRP_HEUR200 error message.
