SAP Fiori Cache Cleanup: A Comprehensive Guide
Understanding the Need for Cache Cleanup
When encountering issues with SAP Fiori apps, such as slow loading times, missing icons, or incorrect data, clearing the cache can often resolve the problem. Cache cleanup is essential after system upgrades, configuration changes, or deployment of new Fiori apps.
Key Areas for Cache Cleanup
To effectively address Fiori-related issues, you need to clear the cache in three primary areas:
1. Client-Side Cache:
-Browser Cache: Delete browser history, cookies, and cache to ensure the latest version of Fiori apps is loaded.
2. Frontend Server Cache:
-SAPUI5 Application Index: Recalculate the index using report `/UI5/APP_INDEX_CALCULATE` to ensure accurate app information.
-Page Cache: Synchronize the page cache using report `/UI2/PAGE_CACHE_SYNCHRONIZE` (for SAPUI5 7.58 and above) or invalidate the cache manually in SMICM (for earlier versions).
-Metadata Cache: Invalidate the metadata cache using report `/n/IWFND/CACHE_CLEANUP` to refresh app metadata.
-UI2 Cache: Invalidate global UI2 caches using report `/UI2/INVALIDATE_GLOBAL_CACHES`.
3. Backend Server Cache:
-Metadata Cache: Invalidate the metadata cache for the Gateway service using report `/IWBEP/CACHE_CLEANUP`.
Additional Considerations for S/4HANA Fiori
For S/4HANA Fiori, additional steps are required to ensure optimal performance and functionality:
– Activate and Maintain Services: Activate services like `/UI2` and SICF services for application resources using transaction `/IWFND/MAINT_SERVICE`.
– Configure SAP Gateway:** Configure SAP Gateway to enable OData queries and proper data exchange between the frontend and backend systems.
– Assign Necessary Roles:** Ensure that users have the required roles, such as `SAP_UI2_ADMIN_731`, to access and manage Fiori apps.
Common Fiori Issues and Troubleshooting
– Cannot Load Tiles: Check for errors in the Fiori Launchpad configuration, network connectivity issues, or incorrect user permissions.
– Missing Tiles or Catalogs: Review the Fiori catalogs and roles assigned to users. Ensure that the necessary catalogs and apps are activated.
– App Cloud Not Opening: Verify the app URL, network connectivity, and user authorization.
– Fiori Activation Task List Issues: Check the task list for errors or incomplete tasks.
– Blank Screens: Inspect the browser console for JavaScript errors or network issues.
