• What is the cause and solution for SAP error message /UI2/GLOBAL_CACHES019 - &2: &1 instances invalidated for all users in all clients ?

  The SAP error message /UI2/GLOBAL_CACHES019 &2: &1 instances invalidated for all users in all clients typically indicates that certain cache instances have been invalidated across all users and clients in the SAP system. This can happen for various reasons, often related to changes in the underlying data or configuration that affect the cached objects.
  Cause:
  
  Data Changes: Changes in the underlying data model, such as modifications to OData services, changes in the UI5 application, or updates to the backend data structures.
  Configuration Changes: Changes in the configuration of the SAP Fiori applications or the underlying SAP Gateway settings.
  Transport Requests: When transport requests are imported, they may invalidate existing cache instances.
  System Maintenance: Regular system maintenance activities, such as system upgrades or patches, can also lead to cache invalidation.
  Manual Cache Clearing: Administrators may manually clear caches for troubleshooting or performance reasons.
  
  Solution:
  
  Rebuild the Cache: After the invalidation, the system will automatically rebuild the cache as users access the affected applications. However, you can also manually trigger a cache refresh if necessary.
  Check for Changes: Review any recent changes made to the system, including configuration changes, transport imports, or data model updates, to understand what might have triggered the invalidation.
  Monitor System Logs: Check the system logs (transaction SLG1) for any related messages that might provide more context on the invalidation.
  Clear Cache Manually: If necessary, you can manually clear the cache using transaction /UI2/FLP or /IWFND/MAINT_SERVICE to ensure that the cache is rebuilt correctly.
  User Communication: Inform users about the cache invalidation, as they may experience delays or issues until the cache is fully rebuilt.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to cache invalidation or provide guidance on best practices for managing cache in SAP Fiori applications.
  Performance Monitoring: Regularly monitor the performance of your SAP Fiori applications to identify any potential issues related to caching.
