how to provide destination configurations in SAP cloud foundry environment ?

I am trying to consume on premise odata service by deploying third party application in SAP cloud foundry environment.

While trying to hit the service I am getting error: No Xsuaa access token found for the user

It seems that this is the initial step where authentication to the on premise system is failed.

Onpremise server + cloud connector settings are already done and exposed to internet on server side.

Kindly let me know how to configure destination in SAP cloud foundry.
