Did you get your system working correctly, or are you still having this issue?
If you are, when you ran SAPINST on the target system, did you run with the option for "database copy completion"? If you did, there should have been a fairly long-running and obvious step in there where the tool moved objects from the source system schema to the target system schema.
Which version of SAPINST are you using, and where did you obtain it from? It makes a difference, whether you obtained it via the new 70SWPM tool, or if it's the old SAPINST.
