For recursive Analyses such as below :
PrevVal(tagA,'*') + 'TagB' → output : tagA

When the PI Analysis Service is down (or the node needs to be restarted), the current calculation needs to be halted until the Backfilling reaches up to the start up time. Or else the value will not be as expected.

It would be great to have the ability to hide the Event Frame End Time in the Notification Email when the notification first triggers.
At this time, and End Time of 12/31/9999 11:59:59 PM Central Standard Time (GMT-06:00:00) is displayed even though an event is not closed.
Note: in this case notifications have been set up to send at Event Start and End Time.

Allow a different naming pattern for the child event frames. End result would have the long, uniquely named EFs in the Parent EF as usual, but the Child EFs could have a simplified name, like the level of an alarm that is pulled from an attribute value (capable as of AF 2017 R2).

We've several PI servers and AF servers where same products are running, so we need the ability to search Event Frames across our AF databases to compare production performance. This search ability should be available in all clients; PI Vision, DataLink etc.

As an AF Administrator, I want to configure an Analysis Template for Event Frames with a True For parameter that would have it's value stored in an AF Attribute (configuration item). The use case is that elements built from the template will have Event Frames that will require a different True For value. I would like to have the analysis both base off a template and with the possibility of having different True For values. It would also be nice to have a True For parameter for the End Time. This is already a request:

When i create a derived Element Template, i would like to be able to override an inherited analysis. Now i am severly limited in the re-use of templates due to this limitation. I cannot extend nor exclude functionality in a derived template if this is used in an analysis, because i cannot adapt the inherited analysis.

This is similar to https://feedback.osisoft.com/forums/555148-pi-server/suggestions/17865355-exclude-analysis-function
but the two would complement each other quite well

Formula data references do not support string value type attributes (e.g. if stringattribute="Yes" then "X" else "Y"). One workaround is to create an analysis on the element template with the same logic mapped to an attribute on the element template. In certain cases, however, an analysis will not work.

For example, for an event frame with manually-entered string data individual to each event frame that then determines the value of another event frame attribute based on IF/THEN logic), we need this value to be calculated per event frame and not on the element.

Add the capability to perform scheduled backfills for a specific time frame, for analyses created on PI System Explorer.

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.

In AF please provide a way to suppress time zone and/or to format the timestamp in AF Events, particularity, Notifications. For example, in the message format in e-mail notification I do not need to indicate the time zone it was triggered in.
Please make this available in the AF SDK as well as in PI System Explorer.

As an AF user, I would like to be able to store a tag’s instrument tag value in an attribute so that it can be used in the content of a Notification. For example, notifying someone on data from a PING interface where the instrumenttag property holds the IP Address.

I am able to create an AF analysis to store a tag’s description in an attribute using the TagDesc PE function, but there is no similar PE function to pull in a tag’s instrument tag.

As a PI Administrator with a test PI Server, I need to be able to easily promote configurations from our test environment to our production environment. Currently this is extremely difficult and a very manual process.

As an engineer I need the option to not capture values for event frames generation so that if I have out-of-order events, I don't have to recapture the values.

Note: This was previously Enhancement 114349.

Provide the capability to apply compression on uncompressed data, aka recompress using offline archive utility.  See work item 6944OSI8.

Using the Max Rollup function - I would like to know which element provided the maximum value and output this as well so I can historize the information.

We have hundreds of mappings/trusts in SMT and there's no way to search them (apart from exporting it all to Excel, and searching there, then going back to SMT to make necessary changes - not user friendly). There needs to be a basic search bar at the top of that panel, and it should search all fields (except server and collective) in whatever tab has focus (mappings or trusts). 

Ability to link Event Frames coming in from different sources (batch & mes interfaces, EFgen, PI Analytics, custom, etc.) together based on rules and monitoring an EF attribute SO THAT it's easier to associate time frame context and data that is related together but come from different sources.
