• What is the cause and solution for SAP error message /UI2/CACHE009 - Failed to read due to expiration ?

  The SAP error message /UI2/CACHE009 Failed to read due to expiration typically relates to issues with the SAP Fiori cache. This error indicates that the cache for a specific UI component has expired, and the system is unable to retrieve the necessary data from the cache.
  Cause:
  
  Cache Expiration: The cache for the UI components has a defined expiration time. Once this time is reached, the cache is invalidated, and the system cannot read from it.
  System Configuration: The cache settings may not be configured optimally, leading to frequent expirations.
  Changes in UI5 Applications: If there have been updates or changes to the UI5 applications, the cache may need to be refreshed to reflect these changes.
  Server Issues: Temporary server issues or network problems can also lead to cache read failures.
  
  Solution:
  
  
  Clear the Cache: 
  
  You can manually clear the cache using transaction code /UI2/FLP or /UI2/FLP_CUST in the SAP GUI. This will refresh the cache and allow the system to rebuild it.
  Alternatively, you can use the transaction /UI2/FLP_CLEANUP to clean up the cache.
  
  
  
  Adjust Cache Settings: 
  
  Review and adjust the cache settings in the SAP Fiori Launchpad configuration. You may want to increase the cache expiration time if it is set too low.
  
  
  
  Check for Updates: 
  
  Ensure that all UI5 applications are up to date. If there have been recent changes, consider redeploying the applications to refresh the cache.
  
  
  
  Monitor System Performance: 
  
  Keep an eye on system performance and logs to identify any underlying issues that may be causing frequent cache expirations.
  
  
  
  Restart Services: 
  
  In some cases, restarting the relevant services or the entire SAP system may help resolve transient issues.
