Other user can not see the data from the workbook

Question

Hi Friends,
I created a workbook with some worksheets in a Business area. The owner of the workbook has no problem to view all the worksheets and get all the data returned.. I granted all the neccessary privileges to other users ,they could see the workbook, but no data returnd for the query results. Tried refresh the worksheet, same no data retrieved.Checked the SQL inspector and the plan, it showed the correct paths and execution plan without any errors there. The same query run in SQL plus by other users returned data correctly.
By the way, I had a summary folder in the workbook. During the troubleshooting, I dropped this summary folder, still the same no data return for other users.
Any body happen to know the cause or has some ideas on this issue?
The discoverer administrator verson is 9.0.4.00 and the PLUS /Viewer is 9.04.45.02.
Thank you very much,
J.K

Hi All
The scheduling of reports, as you have probably noticed, requires that the scheduling privilege within Discoverer Administrator tool be granted to the user NOT to a role. Scheduling will not work if you attempt this. The reason for this is that these two SYS grants must go to a user:
GRANT SELECT ON SYS.V_$PARAMETER
GRANT EXECUTE ON SYS.DBMS_JOB
The user will also need to have these grants:
CREATE PROCEDURE,
CREATE TABLE,
CREATE VIEW,
EXECUTE ANY PROCEDURE,
UNLIMITED TABLESPACE on user's tablespace
My new Discoverer 10g Handbook, which I would recommend to anyone working with Discoverer, explains scheduling in detail and even tells you how the tables and views that are used to store the results work. You won't find this information anywhere else, as you will see if you read some of the five reviews that have been left on Amazon.com. For more information about the book please look here:

The PUBLIC grants are not having any impact. All these do is ensure that ALL users have the same basic privileges. You can just as easily grant these to any role of your choosing and it will work just fine.
By the way, because the PUBLIC role is the MINIMUM privileges that a user can have you might want to consider reducing the end user Discoverer privileges afforded to PUBLIC. By default, all users can Create and Edit workbooks, share workbooks, save workbooks and so on. This is far too rich a set of privileges for the basic user, who in most cases will be a VIEWER user. Whenever I create a new EUL I always recommend that my client reduces the PUBLIC user's privileges and then create new roles for more advanced VIEWER and PLUS users, adding privileges as required.
Thus, my basic VIEWER, aka PUBLIC, has only these privileges:
Collect Query Statistics
Item Drill
Drill Out
My advanced VIEWER has this additional privilege:
Save Workbooks to Database
My basic PLUS user has all of the above, plus these (pardon the pun):
Create/Edit Query
Create Link
and my advanced PLUS users get everything, which means they now get these as well:
Grant Workbook
Schedule Workbooks
I also remove the Save / Save As Actions link from Viewer which prevents the basic VIEWER users from knowing that it is there. In essence, because these users no longer can click the Save link and because they do not have the Save to Database privilege, they will not be prompted to save within Viewer no matter what they do. This now makes 10.1.2 Viewer work the same way as previous versions.
Even though the Save link is not there, my advanced Viewer users will be prompted to save if they have made any changes. This therefore allows you to have two classes of Viewer, one who can save and one that cannot.
I hope this helps
