importing crystal reports into costum reports

we're currently on ECC 6.0

I would like to import my reports into storage scope so they can run on a schedule.  The reports are built using tables from RAMBDB and they run perfectly fine within crystal.  However after importing them, they fail to run in storage scope.  I looked at some of the builtin reports, they seem to be pulling data from all kinds of DBs, but never from RAMBDB.  So how do I make this work? do I need to build my reports using a different database?  which would contradict what's stated in the documentation.

Thanks
