Hi,

It seems that the Reused Library used by the original SAP Fiori application, cannot be found in the on-premise system where the SAP Fiori application is located. 
I suggest trying to access this link directly in your browser (within internal network), with the direct host and port of your on-premise system (as defined in the Cloud Connector):
https://<on-premise-system-host>:<port>/sap/bc/ui5_ui5/sap/FIN_VEN_LITS/sap/fin/arp/lib/lineitems/library.js
If you still get a 404 error with a direct access to the system, then I suggest checking that the FIN_VEN_LITS library is installed and activated in your system.
You can also look for the SAP Fiori original application that you are extending here: https://fioriappslibrary.hana.ondemand.com/sap/fix/externalViewer/ and make sure that all its required configurations under section "Implementation Information" -> "Configurations" are done in your on-premise system.

Thanks,

Rotem

Hi lokijana,

I had this issue in the past when I was still working on customer side and it was always related to CORS issues. I normally fixed it by using a browser extension like CORS Unblock, which was easier than explaining it to administrators and waiting for them to fix it. You should be able to see in the Network tab of the Chrome Developer Tools if this is the case.

BR,
Alex
