Event-Trigger by archive data
Currently the Event-Trigger of an analysis works only with data from the snapshot. For my use cases it is necessary to trigger analysis from events in the data archive. This is not possible at the moment. Ideally I would like to configure for each event-triggered analysis separately if it should be triggered by snapshot data and/or archive data.
This is in PI Server 2017 R2, available now on https://techsupport.osisoft.com/
In our PI-system we receive provisional data that later is replaced by obligatory data (on the same time stamp). So when the obligatory data comes in all depended analyses (automatically) have to be recalculated. Doing this manually is not effective.

Can you clarify what it means to be event-triggered by archive data? Are you saying you need it to be triggered by Out of Order events as in whenever a new event is entered into archive, you would want to trigger off of that new event? What would you want to do with events that are replacing other events or events at the same timestamp?
This seems like you are in fact asking for auto-backfill/recalculation. Is that the case?
