Amr,
The best that I can determine, there is no official documentation from BusinessObjects regarding a method to "trim" the Auditor database.  Based on previous disucssions, I seem to remember that you are on XI R2, but if I'm wrong, then these notes will not apply to you.  Here is the scoop:
There are six tables used by Auditor: 1) APPLICATION_TYPE (initialized w/ 13 rows, does not "grow") 2) AUDIT_DETAIL (tracks activity at a granular level, grows) 3) AUDIT_EVENT (tracks activity at a granular level, grows) 4) DETAIL_TYPE (initialized w/ 28 rows, does not "grow") 5) EVENT_TYPE (initialized w/ 41 rows, does not "grow") 6) SERVER_PROCESS ( (initialized w/ 11 rows, does not "grow")
If you simply want to remove all audit data and start over, then truncate AUDIT_EVENT and AUDIT_DETAIL.
If you want to only remove rows based on a period, then consider that the two tables, AUDIT_DETAIL and AUDIT_EVENT, are transactional in nature, however, AUDIT_DETAIL is a child to the parent table AUDIT_EVENT, thus you will want to remove rows from AUDIT_DETAIL based on its link to AUDIT_EVENT before removing rows from AUDIT_EVENT first.  Otherwise, rows in AUDIT_DETAIL will get "orphaned" and never be of any use to you, and worse, you will not readily know how to ever delete these rows again.
Here is the SQL statements:delete from AUDIT_DETAILwhere event_id =(select Event_ID from AUDIT_EVENT                  where Start_Timestamp between '1/1/2006' and '12/31/2006')godelete from AUDIT_EVENT                  where Start_Timestamp between '1/1/2006' and '12/31/2006'go
One word of caution is to down you BOE application before doing this maintenance work, otherwise there is a possibility that Auditor will be busy trying to bring new rows to your database while you're busy delete rows and you might encounter an unwanted table lock, either on the work you're doing or the work that BOE is trying to perform.
Good luck!
