Flashback in Timeline Views
If the Oracle database you are using has Flashback enabled, you can configure your Timeline View so that end-users can execute it in the context of a previous point-in-time.
To enable Flashback, add the following to your Filters. (We have made it a "dynamic" filter, but you may opt not to make it dynamic.)
<CustomFilterField dynamic="true"> <FieldRef category="PDF" levelType="Undefined"> <FieldName>FlashbackTime</FieldName> </FieldRef> <Hidden>false</Hidden> <Editable>true</Editable> <Type>DATE</Type> <Optional>true</Optional> <SimpleMapping sqlName="FLASHBACK_TIME"/> </CustomFilterField>
The name FlashbackTime is a reserved keyword in ONE. When present, this filter will indicate to the server that it should apply the user's given date/time when executing the Timeline View data measure SQLs, so that the results returned reflect the point in time given by the user.
Please note - if Flashback is not enabled in Oracle, or if the user selects a FlashbackTime which exceeds the undo_retention setting in Oracle, the user will receive an explanatory error message.
