Errors while Creating Summary

Question

While creating Summary on some of the folders based on custom views using ASM or mannually, I am getting this fine grain access policy error.
ORA-30372: fine grain access policy conflicts with materialized view
While creating Summary using query statistics, I am getting this following error.
ORA-30353: expression not supported for query rewrite
We are using Discoverer 10g. We have an APPS mode EUL and I am doing this by logging into Discoverer Admin as EUL owner, which is EUL_US. This user has all the previlages specified in Discoverer Admin Doc.
ORA-30372, I could figure out is the problem with tables HZ_ORGANIZATION_PROFILES and HZ_PERSON_PROFILES which I used in the view for the folder I need to summarize.
Tried creating materialized views on these folders seperately in SQL plus, but have the same error.
Can Somebody help me to get through this?

Hi
I am not saying you cannot use summaries but that you have to be aware of the underlying security. Most of the time you will need to use an external summary table not one that has been created for you by Discoverer.
The following snippet, which will help, is taken from the Oracle Business Intelligence Discoverer Administration Guide, found here: http://download-east.oracle.com/docs/html/B13916_04/orapps_supp.htm#sthref1165
As the Discoverer manager of an Oracle Applications mode EUL you must be aware of the following:
1. Some Oracle Applications database views contain row level security and return differing result sets depending upon the currently active responsibility. This means that materialized views (summary tables in Oracle Standard Edition databases) will contain different data depending on the responsibility of the user refreshing the external summary folder.
2. A summary folder based on an Oracle Applications secure view or Oracle Applications business view must be registered in Discoverer as an external summary folder (for more information, see Chapter 14, "How to create summary folders based on external summary tables").
3. Where an external summary folder is mapped against a table or view with Oracle Applications row level security, it is your responsibility as Discoverer manager to make sure the external table or view provides secure access. If you are not sure, ask your database administrator.
4. If a managed summary folder is found that satisfies a query (based on data with Oracle Applications row level security), Discoverer informs the end user that no rows satisfy the query criteria. Discoverer does this to ensure that end users do not see data they should not have access to.
5. If a managed summary folder is found that satisfies a query (based on data without Oracle Applications row level security), Discoverer returns the rows unaffected. Discoverer does this because the data can be safely accessed by all end users.
6. Some Oracle Applications views with row-level security support "public" rows (particularly Human Resources).
I hope this helps
