Easiest way to do this is to create the report against a SQL Query via the 'Add Command' option. The SQL would be:
Select * from ACCOUNTBILLFEE A Where Exists
(Select * from ACCOUNTBILLFEE B where B.FOLDERSN = A.FOLDERSN AND B.STAMPDATE IN (TO_DATE('2014/05/01 00:00:01', 'YYYY/MM/DD HH24:MI:SS' TO TO_DATE('2014/05/31 23:59:59', 'YYYY/MM/DD HH24:MI:SS'))
