ORA-00904: "USERNAME": invalid identifier

Dev. MusbahMar 5 2017 — edited Mar 28 2017

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
