• What is the cause and solution for SAP error message /UI2/GLOBAL_CACHES029 - &2: &1 instances invalidated for all users in all clients (incl. CONF) ?

  The SAP error message /UI2/GLOBAL_CACHES029 indicates that certain instances have been invalidated for all users in all clients, including the configuration client (CONF). This typically relates to the caching mechanism used in SAP Fiori/UI5 applications, where certain cache entries are invalidated due to changes in the underlying data or configuration.
  Cause:
  
  Changes in Configuration: The most common cause for this error is a change in the configuration of the Fiori/UI5 applications, such as updates to the OData services, changes in the UI5 libraries, or modifications in the application settings.
  Transport Requests: If transport requests are moved between systems, it can lead to cache invalidation if the transported objects affect the cache.
  System Maintenance: Regular system maintenance activities, such as system upgrades or patches, can also trigger cache invalidation.
  Manual Cache Clearing: If a system administrator manually clears the cache, it can lead to this error message being displayed.
  
  Solution:
  
  
  Rebuild the Cache: The primary solution is to rebuild the cache. This can be done by executing the following transaction codes:
  
  /UI2/FLP: This transaction can be used to refresh the Fiori Launchpad cache.
  /IWFND/CACHE: This transaction can be used to clear the OData service cache.
  /UI2/FLP_CACHES: This transaction can be used to manage and clear the Fiori Launchpad caches.
  
  
  
  Check for Updates: Ensure that all relevant components (like UI5 libraries and OData services) are up to date and properly configured.
  
  
  Monitor Transport Requests: If the issue arose after a transport, check the transport logs and ensure that all necessary objects were included and properly imported.
  
  
  System Restart: In some cases, a system restart may help in refreshing the cache and resolving the issue.
