The SAP Cloud connector is a free offering from SAP that allow you to connect to BTP ABAP and S4HANA cloud environments. There are SAP certifications for these types of solutions as well which would allow us to certify Fuse for additional SAP platforms. This may just be a matter of a POC with the cloud connector and documenting how to do it. It's quite possible we can support these additional platforms without any code changes.
