Unable to fetch data from on premise system using s4sdk

Question

I followed the tutorial: https://open.sap.com/courses/s4h13/items/258qEhXx5kdG8b4SXMSJYp I am able to fetch data from mocked service, but I get an empty array when I add an on premise sap system in my destination. I am trying to read ProductMaster service (which is available in my sap system). any guidance or link of correct blog will be much appreciated.

Answer 1

When connecting against an On-Premise system, you need to have a connectivity service instance bound to your application, in addition to xs-uaa and destination service instances. Also, make sure that you have configured the Cloud Connector correctly. The following deep dive describes the required prerequisites to connect to S/4HANA OP from SAP Cloud Platform Cloud Foundry (see the abstract Running Business Partner Calls Against S/4HANA On-Premise)

Answer 2
