Hi Elena,
any progress on this issue?
I am also using DS 1.6 SP01 Patch 1 on BIP 4.1 SP06 and cannot use my Universes.
They are based on simple Excel sheets for prototyping, Universes work fine with Webi, but in Design Studio I get the error "failed to initialize data source" once I try to edit the initial view.
Thanks
Alex
