we have installed the Discovery System V3 sucessfully. Currently the SPROXY points to the PI 7.0 integration repository of the DS. We additionally set up a CE 7.1 system with the Enterprise Services Repository. Now I would like SPROXY to point to the ESR of CE 7.1. How can I accomplish this? I already found the solution with the RFC-Destination SAP_PROXY_ESR in SM59, but looks like this only works in 7.0 systems with SPS 14 or higher, we are on 12.
