• What is the cause and solution for SAP error message AUR028 - Simulation index no longer available or is outdated ?

  The SAP error message AUR028, which states "Simulation index no longer available or is outdated," typically occurs in the context of the SAP Advanced Planning and Optimization (APO) module, particularly when dealing with demand planning or supply network planning.
  Cause:
  
  Outdated Simulation Index: The simulation index may have been deleted or not updated after changes were made to the planning data. This can happen if the planning data has been modified, and the simulation index has not been refreshed accordingly.
  Data Deletion: If the underlying data that the simulation index relies on has been deleted or altered, the index may become invalid.
  System Configuration Issues: There may be configuration issues in the APO system that prevent the simulation index from being accessed or updated properly.
  
  Solution:
  
  
  Recreate the Simulation Index: 
  
  You can recreate the simulation index by running the relevant planning functions or processes that generate the index. This is typically done through the transaction code /SAPAPO/SDP94 or similar, depending on your specific scenario.
  Ensure that the planning area and data are correctly set up before recreating the index.
  
  
  
  Check Data Consistency: 
  
  Verify that the underlying data (like master data, transaction data, etc.) is consistent and has not been deleted or corrupted. You may need to run consistency checks or data validation processes.
  
  
  
  Update Planning Data: 
  
  If there have been changes to the planning data, ensure that all relevant data is updated and that the simulation index is refreshed accordingly.
  
  
  
  System Configuration Review: 
  
  Review the configuration settings in the APO system to ensure that everything is set up correctly. This may involve checking the planning area settings, data sources, and other related configurations.
  
  
  
  Consult Documentation: 
  
  Refer to SAP documentation or notes related to the specific version of APO you are using for any additional troubleshooting steps or known issues.
  
  
  
  Contact SAP Support: 
  
  If the issue persists after trying the above solutions, consider reaching out to SAP support for further assistance. They may provide patches or additional guidance based on your specific system configuration.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /SAPAPO/SDP94 for demand planning and /SAPAPO/OM17 for checking the simulation index.
  SAP Notes: Check for any SAP Notes related to AUR028 for specific fixes or updates that may address the issue.
  User Forums: Engage with SAP community forums or user groups where similar issues may have been discussed, and solutions shared.
  
  By following these steps, you should be able to resolve the AUR028 error and ensure that your simulation index is up to date and functional.
