OBIEE Dashboard Page State Persistence

When you are viewing a report which was configured to “drill in place” in section.
You might observe that the drill down reports in Dashboard Pages are not displaying results which are related to that; instead it displays results which are last seen on that particular Dashboard Page where you drilled down from its level.
For e.g.: I have a report which has drilled down from year to month in dashboard.
drilldown1
Now if you click on the Drill down Test page still I am seeing the same granular level report instead of original report;
drilldown2
This is because our OBIEE is maintaining the dashboard page state by default.
To handle this we need to configure page state maintenance and for this add PersistPageState parameter in instanceconfig.xml as it determines whether page state is persisted when moving between pages on a dashboard. By default this parameter was set to “True” now change this value to “False”.
The parameter you have to add in instance config.xml after <ServerInstance>element is:
 <PersistPageState>FALSE</PersistPageState>
Now restart the Presentation server and Java host, check the reports and see that the dashboard page not maintains its page state.
