    OK, there may be many reasons for this.

    1. You didn’t recreate the MV yet in 11g. You can’t refresh an MV to create it.

    2. You didn’t recreate a synonym (public or private) to the schema where the MV is located.

    3. You didn’t recreate grants to the MV in another schema, so create them.

    You might try DBMS_MVIEW instead of DBMS_SNAPSHOT.

    exec dbms_mview.refresh('Table1');
