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.
