Regarding slow speed (Performance) of OBIEE Dashboard Report.

Question

Hi All,
We have developed a dashboard for Finance & Accounting Dept. This contains 5 reports of different types like Location Wise Expense report, Level code based Expense Report, etc.
*There are two Databases for this.
1: XYZ for employee records like Level code, Location etc.
2: ABC for Travel Expenses records.
Both are in same server.*
In these Reports , We have done Row wise totals for more than one Columns like Level code wise total, location wise total etc. in same report.
Also, few calculations are also there in all the reports as it is related to Finance Dept.
Only in one report out of five, we have used PIE graph. Else all are in form of tables.
We have also used
SUM (Travel."Total Cost" by
CASE WHEN "Purp Of Visit"."Purpose description" LIKE 'NA' THEN 'Others'
WHEN "Purp Of Visit"."Purpose description" LIKE 'Customer%' THEN 'Customer Related'
ELSE "Purp Of Visit"."Purpose description" END ) / 1000
Problem is that these reports run very slow when Client see them on Dashboard.
It takes around 1-2 minutes to load data in dashboard.
Other dashboard reports run normally and data can be seen in 5-10 seconds.
We desperately want to decrease the data fetching time of reports from database.
Please help if anyone of you know some good solution for this problem.
Thanks in advance..
Rgards,
Saurabh.
