Trying creation of KPI tiles on SCP HANA OData-Service

Hello experts,

I followed Blog:

https://blogs.sap.com/2016/06/27/create-your-first-smart-business-kpi-and-tiles-in-10-minutes/

As far it worked well. Now I tried to create an own Destination "BusinessSystem01" with existing OData service within SCP HANA DB:

https:// trial.hanatrial.ondemand.com/sap/hana/democontent/epm/services/salesOrders.xsodata

But I got no Source System "BusinessSystem01" for value help in "Create KPI" app. I tried to make manuell entries but have no information about what "Entity Set" is (the table like SalesItem?).

Any experiences or ideas? Maybe a hint for another good blog showing how to do this based on SCP HANA?

Thanks in advance!

Peter
