• What is the cause and solution for SAP error message /SAPAPO/OM421 - Old transactional simulations deleted (saved, inactive, not at database) ?

  The SAP error message /SAPAPO/OM421 Old transactional simulations deleted (saved, inactive, not at database) typically occurs in the context of SAP Advanced Planning and Optimization (APO) when dealing with transactional simulations. This message indicates that the system has detected that certain old transactional simulations have been deleted or are no longer available in the database.
  Cause:
  
  Old Simulations: The error is triggered when the system attempts to access transactional simulations that have been marked as old or inactive. These simulations may have been deleted from the database or are no longer relevant.
  Data Cleanup: Regular data maintenance or cleanup processes may have removed these simulations, leading to this error when trying to access them.
  System Configuration: There may be configuration settings that dictate how long simulations are retained in the system, and if they exceed this timeframe, they may be automatically deleted.
  
  Solution:
  
  Check Simulation Status: Verify the status of the simulations you are trying to access. If they are indeed marked as inactive or deleted, you will need to create new simulations.
  Create New Simulations: If the old simulations are no longer available, you can create new transactional simulations as needed.
  Review Data Retention Policies: Check the configuration settings related to data retention for simulations in your SAP APO system. Adjust these settings if necessary to retain simulations for a longer period.
  Consult Documentation: Refer to SAP documentation or notes related to this error message for any specific recommendations or patches that may address the issue.
  System Logs: Review system logs for any additional error messages or warnings that may provide more context about the deletion of simulations.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or updates related to this error message. SAP frequently releases notes that address specific error messages and provide guidance on how to resolve them.
  Transaction Codes: Familiarize yourself with relevant transaction codes in SAP APO that deal with simulations, such as /SAPAPO/OM01 for managing simulations.
  User Authorization: Ensure that you have the necessary authorizations to create and manage simulations in the system.
  Backup and Restore: If the simulations are critical, consider implementing a backup strategy to prevent loss of important data in the future.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP Basis or APO support team for further assistance.
