I am upgrading 4.7 to ECC6 and I want to import Enhancement Pack 3 during upgrade. This way is supported by SAPUP. There are two ways - specify Enhancement Package3 files by XML file generated by solution manager. This way is working OK. But the second way - that SAPUP should connect to Solution Manager via the 4.7 system and should calculate necesary files to be downloaded is not working. There is message No Connection to Solution Manager system. I have the system connected to SM, there is trusted RFC working between systems and SM is configured as master system in SDCCN.
So my question is: how to connect 4.7 to SolMan to be able generate EHP3 queue via SAPUP.
