• What is the cause and solution for SAP error message /UI2/GLOBAL_CACHES028 - &1 Instances of &2 will be invalidated in all clients (incl. CONF) ?

  The SAP error message /UI2/GLOBAL_CACHES028 indicates that there are instances of a certain object (denoted by &2) that will be invalidated across all clients, including the configuration client (CONF). This message typically arises in the context of the SAP Fiori/UI5 framework, where caching is used to improve performance.
  Cause:
  The error message is triggered when there is a change in the underlying data or configuration that affects the cached instances of a particular object. This could be due to:
  
  Changes in the UI5 application: Modifications to the application, such as updates to the OData services, changes in the UI5 libraries, or alterations in the configuration settings.
  Transport requests: When transport requests are imported, they may lead to invalidation of cached objects.
  System maintenance: Activities like system upgrades, patches, or other maintenance tasks can also cause cache invalidation.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Clear the Cache: You can manually clear the cache for the affected objects. This can be done using transaction codes like /UI2/FLP_CLEANUP or /UI2/FLP_CLEANUP in the SAP GUI. This will refresh the cache and ensure that the latest versions of the objects are loaded.
  
  
  Check for Updates: Ensure that all relevant components, such as the SAP Gateway and UI5 libraries, are up to date. If there are any pending updates or patches, apply them.
  
  
  Review Transport Requests: If the issue arose after a transport, review the transport logs to ensure that all objects were transported correctly and that there are no inconsistencies.
  
  
  Monitor System Changes: Keep track of any changes made to the system that could affect the cache. This includes configuration changes, updates to OData services, or modifications to the UI5 applications.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error message or provide additional guidance.
