How can I connect my SAP BTP Kyma with my On-Premise system (ECC6 EHP7) via RFC

[techops-team]

I have an ABAP application that runs on my On-premise system (ECC6 EHP7) with the SAP Connector configured as the image below:

Also, the destination is reachable

On the other side, I have a BTP Kyma environment running my application

My question is... How can I put it all together?

Hi, we are have the same problem, were you able to solve it?

We are getting

In BTP Destinations are defined and are working

In Kyma we have an error when trying to connect

message: Technical connectivity is not configured.

reason: ConfigurationError-ReferencedDestinationServiceInstance-DoesNotExist

In your BTP application, you need to use the built-in JCo to make RFC calls against the destination "demo2". See for example this documentation:

Invoking ABAP Function Modules via RFC | SAP Help Portal

(It also has a sample Web Application that illustrates a simple function call.)

that article only refers to the SAP BTP (CloudFoundry environment), not Kyma. In Kyma the container images are custom built and have no built-in JCo. The question is, is it enough to package the JCo (downloadable from SAP) maybe paired with the SapMachine Java JDK during custom container image creation? The SAP documentation is very fuzzy, i.r.t. connector from a Kyma environment via RFC to a SAP instance.
