• What is the cause and solution for SAP error message /UI2/PAGEBUILDER203 - UI2 Cache Invalidation triggered ?

  The SAP error message /UI2/PAGEBUILDER203 indicates that there is a cache invalidation triggered in the UI2 framework, which is part of the SAP Fiori and SAP UI5 technology stack. This message typically occurs when there are changes made to the UI5 application or its components, such as changes in the OData service, changes in the UI5 application itself, or updates to the underlying data model.
  Cause:
  
  Changes in the Application: If there are modifications to the UI5 application, such as changes in the views, controllers, or models, the cache may need to be invalidated to reflect these changes.
  OData Service Changes: If the underlying OData service has been modified (e.g., new fields added, changes in the service metadata), the cache may be invalidated to ensure that the latest data is fetched.
  Deployment of New Versions: When a new version of the application is deployed, the cache is invalidated to ensure that users are accessing the latest version.
  Manual Cache Invalidation: Sometimes, administrators may manually trigger cache invalidation for maintenance or troubleshooting purposes.
  
  Solution:
  
  
  Clear the Cache: You can manually clear the cache in the SAP Gateway or the SAP Fiori Launchpad. This can often resolve issues related to stale data or outdated application versions.
  
  Use transaction code /IWFND/MAINT_SERVICE to manage OData services and clear the cache.
  Use transaction code /UI2/FLP to access the Fiori Launchpad and clear the cache.
  
  
  
  Check for Updates: Ensure that all components of the application are up to date, including the OData services and UI5 libraries. If there are updates available, apply them.
  
  
  Review Application Logs: Check the application logs for any additional error messages or warnings that may provide more context about the cache invalidation.
  
  
  Restart Services: In some cases, restarting the relevant services (like the SAP Gateway or the Fiori Launchpad) may help in resolving persistent cache issues.
  
  
  Consult Documentation: Refer to SAP documentation or support notes related to the specific version of SAP Fiori or UI5 you are using for any known issues or additional troubleshooting steps.
