Error while fetching lcr.get_logon_user in dml handler.

Question

Hi all,
beacuse of lcr.get_logon_user am getting error in executing this procedure.
CREATE OR REPLACE PROCEDURE history_dml(in_any IN SYS.ANYDATA) 
IS
  lcr   SYS.LCR$_ROW_RECORD;
  rc    PLS_INTEGER;
BEGIN
  -- Access the LCR
  rc := in_any.GETOBJECT(lcr);
  -- Insert information about the LCR into the history_row_lcrs table
  INSERT INTO strmadmin.history_row_lcrs VALUES
   (SYSDATE, lcr.GET_SOURCE_DATABASE_NAME(), lcr.GET_COMMAND_TYPE(),  
    lcr.GET_OBJECT_OWNER(), lcr.GET_OBJECT_NAME(), lcr.GET_TAG(),
    lcr.GET_TRANSACTION_ID(), lcr.GET_SCN(), lcr.GET_COMMIT_SCN,
    lcr.GET_VALUES('old'), lcr.GET_VALUES('new', 'n'),lcr.GET_LOGON_USER() );
  --  Apply row LCR
  lcr.EXECUTE(true);
END;I need the "logon user" also in my log table while doing the dml, but when i add "lcr.GET_LOGON_USER() " into my procedure, it gives me an error saying "PLS-00302: component 'GET_LOGON_USER' must be declared".
Please help.
