  The SAP error message /UI2/PAGEBUILDER201 Page Cache Version Upgrade from version &1 to &2 detected typically indicates that there is a version mismatch in the page cache of the SAP Fiori/UI2 framework. This can occur when there are updates or changes made to the UI components or the underlying data model, which require the cache to be refreshed to reflect the new version.
  Cause:
  
  Version Upgrade: The error is triggered when the system detects that the version of the page cache has changed. This can happen after an upgrade of the SAP system, installation of new UI components, or changes in the application configuration.
  Cache Inconsistency: If the cache is not properly cleared or updated after changes, it can lead to inconsistencies, resulting in this error message.

  Clear the Cache: The most common solution is to clear the cache for the UI2 framework. This can be done using the following steps:
  
  Go to transaction code /IWFND/MAINT_SERVICE and clear the cache.
  Alternatively, you can use transaction code /UI2/FLP to access the Fiori Launchpad and clear the cache from there.
  You can also use the command /UI2/FLP_CLEANUP to perform a cleanup of the cache.
  
  
  
  Check for Updates: Ensure that all relevant components are updated to the latest version. This includes checking for any SAP Notes or patches that may address known issues related to the page cache.
  
  
  Restart the Application Server: In some cases, restarting the application server can help in refreshing the cache and resolving the issue.
