• What is the cause and solution for SAP error message /UI2/CORE_FES001 - Caching of the backend context is inactive ?

  The SAP error message /UI2/CORE_FES001 Caching of the backend context is inactive typically occurs in the context of SAP Fiori applications when there is an issue with the caching mechanism for the backend context. This can affect the performance and responsiveness of Fiori applications.
  Cause:
  
  Caching Configuration: The caching of the backend context may be disabled in the system configuration. This can happen due to specific settings in the SAP Gateway or the Fiori Launchpad.
  System Settings: The system might not be configured to allow caching, or there may be restrictions based on the application or user roles.
  Network Issues: Temporary network issues or connectivity problems between the frontend and backend systems can also lead to this error.
  Backend Service Issues: If the backend service is not responding or is misconfigured, it may prevent the caching mechanism from functioning properly.
  
  Solution:
  
  
  Check Caching Settings:
  
  Go to the SAP Gateway settings and ensure that caching is enabled for the relevant services. This can typically be done in transaction code /IWFND/MAINT_SERVICE where you can check the service configuration.
  Ensure that the Cache option is set to Active.
  
  
  
  Adjust System Parameters:

  You can clear the cache in the Fiori Launchpad by using the transaction /UI2/FLP and selecting the option to clear the cache.
  
  
  
  Check Backend Services:
