    ORA-00904: "USERNAME": invalid identifier

    Dev. Musbah

      Hi All,

      I'm using Oracle DB 11g R2, When I try to make an ER-DIAGRAM using SQL Developer through: file>data modeler>import>data dictionary><database connection>>next

      when I press next this error appears: ORA-00904: "USERNAME": invalid identifier

      Is there a column with this name "USERNAME"? OR why this error occurs?


      Thank you
