Notifications for events in the past
Currently notifications are not triggered (send) by events that are more than 72 hours in the past. For me it is necessary to get notifications from events in the (endless) past. Ideally I would like to configure for each notification separately the time range (from now on backwards) in which the notification should be triggered.
If you use PI Notifications to send for example daily reports and those reports are missed for more than 3 days, then you effectively have lost the ability to send the reports. You must manually create them using other PI client tools. It seems like when you are manually backfilling analyses that generate the notifications, there should be a simple configuration option to increase/decrease the 72 hour setting or disable it all together.

We are using Event Frames and the triggered notifications to a web service delivery endpoint in order to run more complex analyses outside of PI and return the results into the PI system. As notifications to the web service are no longer triggered when backfilling more than 72 hours in the past, we will have to create a separate solution for historical analyses and for live analyses.
Being able to configure the time range within which the notification would be sent when backfilling would allow us to use a single solution for the running system/live analyses and also historical analyses.
I'd like to have this feature for testing notification mails for situations that rarely occur.
For a lot of TAGs we receive the data very late. For example, somewhen between 1st of May and 1st of June we receive a value for the timestamp 1st of April (this value is valid for the whole April). When the data comes in, I need to be informed that it is available in the PI-System so that we can do our monthly technical account for April. The event frame for this event is getting created, but the notification is not triggered, because the timestamp is too far in the past (>72h).

It sounds like this may actually be a request about the creation of the Event Frame rather than the sending of the Notification. Or is it both? Also, if historical EFs are getting created, why is the preference to receive an e-mail instead of just using a client tool to look up the history?
