Query to find all Oracle Discoverer Reports/Workbooks

Run the following sequence of queries in APPS schema to find all Discoverer Reports/Workbooks that exist in the system.

Query1: Run the following query to know the name of table

SELECT owner,table_name
  FROM all_tables
 WHERE owner = 'EUL4_US'
   AND table_name LIKE '%DOCUMENT%';

Generally the above query returns table_name as 'EUL4_DOCUMENTS'
Meaning, all the discoverer report/Workbook names are stored in this table

Query 2: Run the following query to see all reports

SELECT DOC_ID,
       DOC_NAME,
       DOC_DEVELOPER_KEY,
       DOC_CREATED_BY
  FROM EUL4_US.EUL4_DOCUMENTS;

Note:
If the First Query is not returning any data then try the following query and manually find the table name.

   SELECT owner,table_name
     FROM all_tables
    WHERE table_name LIKE '%EUL%DOCUMENT%';

You have to modify the 2nd query in this case with the new OWNER.TABLE_NAME
