Cache Cleanup in SAP Netweaver Gateway

Target Audience: SAP Fiori developers

Dear Readers,

I’m an SAPUI5/ SAP Fiori consultant.This blog is especially for SAPUI5 front end developers.This details about cleaning up of cache through various methods. Cache cleanup is required when we have made changes in the SAPUI5 code but it fails to reflect when the application is accessed through launchpad.


We all would have faced this issue of code changes not reflecting in Fiori launchpad or taking a very large amount of time to reflect in Fiori launchpad after we have made changes in gateway system.

This is because the old code is cached (like how we have cookies in browser , we have cache in gateway too) and hence our new code fails to reflect in the launchpad.


How do you fix  this?

We upload SAPUI5 applications to SAP Gateway system through se38 transaction.


After upload of  applications,we need to manually clear all possible caches so that a fresh copy of our code is taken when we access the app from launchpad.

There are a set of programs and T-codes that clear cache and these are to executed in SAP netweaver gateway


Programs to Delete Cache

Go to Transaction se38 and execute the following programs

1. /ui2/delete_cache_after_imp

2. /ui2/invalidate_client_caches


To recalculate index of an app


Choose tab singleUI5 repository only. Give name of you app and execute


4. To invalidate global cache


give execution mode and execute

WARNING:This restructures the target mapping Index for all apps for all users. Hence should be used with caution


5. To delete metadata cache




T-codes for cache cleanup

Execute the following T-codes

To clear front end cache



To Clear backend Cache




To clear Global Cache

goto->HTTP Plugins->Server Caches->Invalidate globally



Clear all cache of the service


select the service->Service implementation->Cleanup cache

Clear cookies in browser and hit the app from launchpad.The changes you have made in the app will reflect in the launchpad with immediate effect.

      I am hearing that clearing global cache should never be done because it impacts all users and apps.  What is the risk of running this transaction?

      If you restarted the SAP gateway, does it clear cache automatically?

      By restarted i presume you are logging off and logging back in?

      If thats the case it doesn't clear cache automatically

      Hello, great information.

      How long can this execution take?
