• What is the cause and solution for SAP error message /SAPAPO/OM418 - Old transactional simulation without temporary application tables deleted ?

  The SAP error message /SAPAPO/OM418 Old transactional simulation without temporary application tables deleted typically occurs in the context of SAP Advanced Planning and Optimization (APO) when there are issues related to the simulation of planning scenarios. This error indicates that the system has detected old transactional simulations that do not have the necessary temporary application tables, which are required for the simulation process.
  Cause:
  
  Old Simulations: The error is often caused by the presence of old or outdated simulation data that has not been properly cleaned up or deleted.
  Missing Temporary Tables: The required temporary application tables for the simulation process are missing or have not been created.
  System Configuration Issues: There may be configuration issues in the APO system that prevent the proper execution of simulations.
  
  Solution:
  
  
  Delete Old Simulations: 
  
  Navigate to the relevant transaction in SAP APO where you can manage simulations.
  Identify and delete any old or unnecessary simulations that are no longer needed.
  
  
  
  Check Temporary Tables: 
  
  Ensure that the necessary temporary application tables are being created during the simulation process. This may involve checking the configuration settings for the simulation.
  If the tables are missing, you may need to investigate the underlying database or system settings to ensure that they are being generated correctly.
  
  
  
  System Cleanup: 
  
  Perform a system cleanup to remove any obsolete data that may be causing conflicts. This can often be done through standard SAP housekeeping transactions.
  
  
  
  Review Configuration: 
  
  Review the configuration settings in the APO system to ensure that they are set up correctly for simulations. This may involve checking the planning area settings, data sources, and other related configurations.
