• What is the cause and solution for SAP error message /SAPAPO/RRP_HEUR009 - Simulation session was not possible ?

  The SAP error message /SAPAPO/RRP_HEUR009 Simulation session was not possible typically occurs in the context of Advanced Planning and Optimization (APO) when trying to run a simulation for a planning scenario. This error can arise due to various reasons, and understanding the cause is crucial for finding an appropriate solution.
  Possible Causes:
  
  
  Missing or Incomplete Data: The planning data required for the simulation might be incomplete or missing. This can include master data, transaction data, or configuration settings.
  
  
  Locking Issues: If another user or process is currently accessing the same planning object, it may lead to locking issues that prevent the simulation from being executed.
  
  
  Configuration Errors: Incorrect configuration settings in the APO system can lead to issues when trying to run simulations.
  
  
  System Performance: If the system is under heavy load or if there are performance issues, it may not be able to handle the simulation request.
  
  
  Authorization Issues: The user attempting to run the simulation may not have the necessary authorizations to perform the action.
  
  
  Technical Errors: There could be underlying technical issues, such as problems with the APO background jobs or inconsistencies in the database.
  
  
  Solutions:
  
  
  Check Data Completeness: Ensure that all necessary master and transaction data is available and correctly maintained. This includes checking for any missing or incomplete entries.
  
  
  Release Locks: If there are locks on the planning objects, wait for the other processes to complete or manually release the locks if possible.
  
  
  Review Configuration: Verify the configuration settings in the APO system to ensure they are set up correctly for the simulation you are trying to run.
  
  
  Monitor System Performance: Check the system performance and resource utilization. If the system is overloaded, consider running the simulation during off-peak hours.
  
  
  Check Authorizations: Ensure that the user has the necessary authorizations to execute the simulation. This may involve checking roles and permissions in the SAP system.
  
  
  Technical Support: If the issue persists, consider reaching out to your SAP Basis or technical support team to investigate any underlying technical issues or errors in the system logs.
  
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like /SAPAPO/RRP1 (for planning board) or /SAPAPO/RRP3 (for detailed planning) to check the status of your planning objects.
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Documentation: Refer to the official SAP documentation for APO for more detailed information on simulation sessions and planning processes.
  
  By systematically addressing these potential causes, you should be able to resolve the /SAPAPO/RRP_HEUR009 error and successfully run your simulation session.
