This article is taken from SAP Note 2474334 – When to use /UI5/UPDATE_CACHEBUSTER or /UI5/APP_INDEX_CALCULATE.
Depending on your system UI add-On version,
- For system at UI Add-On 1.0, use report
/UI5/UPDATE_CACHEBUSTER.
This report takes care that the cache buster for SAPUI5 app resources works on latest meta data. The cache buster ensures that the application starts as quickly as possible and that the users see the latest UI even after a server side software update, without having to clear the browser cache manually. Note: This affects static resources of SAPUI5 apps, not data content delivered by the SAP gateway. At the same /UI5/RESET_CACHEBUSTER needs to be descheduled. This report would delete the meta data calculated asynchronously by /UI5/UPDATE_CACHEBUSTER. As a consequence the app start would take longer.
If you get the message ‘Report was not executed: Use Report /UI5/APP_INDEX_CALCULATE instead’, this means that you are not longer in SAP UI Add-on 1.0, and /UI5/UPDATE_CACHEBUSTER should not be scheduled.
- For systems at UI Add-On 2.0 or higher, use report /UI5/APP_INDEX_CALCULATE. Report should periodically scheduled.
- For S/4HANA systems the report /UI5/APP_INDEX_CALCULATE is scheduled automatically.
