Hi Experts

I am implementing "Manage Outgoing Checks" Transactional app on my system (S/4 HANA 1511). I have activated desired UI5 and oData services as mentioned in Fiori apps Library. While clicking on tile I am getting following error :-

Hi Parth,

Do you have any solution yet? I'm having the same issue for banking apps.

Many thanks in advance!

Kind regards,

Wouter

Hi Parth Budhiraja,

This error mainly occurs for either of the below reasons

1) Inactive ICF nodes : Please make sure that the ICF service FIN_CHECKMNG is activated in two locations.

Default_Host>SAP>BC>BSP>SAP>FIN_CHECKMNG

Default_Host>SAP>BC>UI5_UI5>SAP>FIN_CHECKMNG

2) Wrong configuration in system alias : Make Sure the system alias is configured properly.

Its always a good practise to clear the cache by running the report /UI2/INVALIDATE_GLOBAL_CACHES in the front end server.

If other apps are working good then the chances of failure are more with (1) and OData service activation.

Hi Virinchy

Thanks for your inputs.

Both oData service FAP_OUTGOING_CHECKS_SRV and UI5 service FIN_CHECKMNG are in place.

I did clear the cache as mentioned by you, but still the issue persists.

I am getting exactly the same error while running Manage Checkbooks application. I guess  It's not related to UI5 or oData service corresponding to particular applications any more.

Thanks

Can you please check and update the support packs to the latest. They are currently at the base versions.

For ex: i see SAP_GWFND , SAP_UI, UIAPF 170 300, UIs4HOP1 100 has 7.50 sp01 available. Please update the other patches also to the latest.

Hi PB,

Negative cache is basically happens due to the way UI5 app loads in files. When you run UI5 you load up a specific file which is the sapui5-core.js file (Name isn’t quite right)

From here the UI5 files loads in other files via a particular file loading process(se38 - /UI5/UI5_REPOSITORY_LOAD) , what happens though with each file that is loaded in is the browser caches that file. Now if a file is loaded in but it has a problem in it the script/application can’t run the file correctly however it is still cached. This triggers the negative cache issue as basically the file is cached but there is a problem with it so what ever is stored in the cache the browser is saying is bad and will always cause an issue.

The first fix is to clear the cache, after that if it doesn’t work you need to look at why that particular file is broken/screwed up.

Perform below steps for cache clearing from Server side:

Tcodes:

1. /n/IWFND/CACHE_CLEANUP,
2. /n/IWBEP/CACHE_CLEANUP,

Goto SE38:

1. run report /UI2/INVALIDATE_GLOBAL_CACHES, F8, select “Execution Mode”, hit F8
2. run report /UI2/DELETE_CACHE_AFTER_IMP
3. run report /UI2/DELETE_CACHE
4. run report CHIP_RESET_CATALOG_CACHE
5. run report /UI2/CHIP_SYNCHRONIZE_CACHE

Go to transaction SMICM

1. Menu options – GOTO – HTTP Plugin – Server Cache – Invalidate Locally and Globally

Browser Cache:

     Clear your browser cache and open in new incognito window(Chrome) or

     inprivate browsing(Internet Explorer).

Hope this helps.

Thanks,

Hi VP

Thanks for your inputs.

Yes our system exists on SP 00 (Initial Stack) version which is a pre-requisite for this app to run.  Still I will tell Basis team to update it to latest.

Hi Joseph

I tried what you said but it did not work for me. Are there any chances to see what particular file is causing rendering issues or rather say which file is broken?

Thanks

Hi Parth,

There are certain central libraries related to SFIN such as fin_lib, fin_arp_lib_cl,fin_arp_lib_li

Please check whether they are activated in SICF.

Hi Karan

Thanks for your inputs. I cross checked the services you mentioned, they all are in place.

Is there anything else I might be missing?

Hi Parth,

This seems to be an issue with some central library service(s) related to SFIN Apps. Please try deactivating and activating them and then clear the cache and try.

Hi Karan

Hi Parth,

Did you perform an update to SP01 to see if it is working ?

Hi PB,

Check whether you have activated FAP_OUTGOING_CHECKS_SRV service?

Hi Joseph

Yep both oData service FAP_OUTGOING_CHECKS_SRV and UI5 service FIN_CHECKMNG are in place.

Thanks
