Oracle Solution for Error ora-34357

ORA-34357: (MXDSS10) string is not an alias of analytic workspace string

.

What triggered the Error:

User attempted to use AW UNALIAS on a non-existent alias.

What should we do to fix it:

Make sure that the command specified the correct analytic workspace and alias. The alias must have been assigned (using AW ALIAS) during the current session and must not have been removed by a previous AW UNALIAS or AW DETACH command.
