While checking our system after the upgrade, we found serveral problems in Z developments caused by a new authorization. We have a lot of communications with external systems (SAP and non-SAP) throw RFC. In order to check the destination is alive we use to call RFC_VERIFY_DESTINATION function module. However we found that administrative priviledges (SM59 tx. authorization) is required in new version.
So, in order to check the destination, we have re-write our Z developments by using RFC_PING fm instead.
