Referencing attributes on other Elements for PI Notifications 2016 Message
Request : Being able to show Attribute values from other Elements other than the attributes on the Referenced Element for the Message in Notification 2016.
Description : From the old version, it was possible for a notification message to display a value not only the target element but also an attribute of other elements (by browsing down elements and selecting the attribute)
In the 2016 version, it does not allow for the user to choose attributes in other elements but only the attributes of the Referenced (or targeted) Element.
The screenshot (Attached file) shows a relative path of an attribute but this is when the user already had a notification rule on the previous version and migrated it. Newly created notification does not have this feature.
It would be very helpful if this would be supported in PI System Explorer again. As Ben Bohringer noted, it still works, it is just missing in the GUI of PI System Explorer.
Using PI Builder, it is possible to manually edit the Delivery Format, and add attributes from other elements:
Adding <osiann:ANInlineContent ContentID="02bb2a93-34ec-4cfc-9624-c1fe5caf4287" ContentProperty="3000" PersistedContentName="..\SiblingElement|Attribute" AdditionalData="" />
for example gets the Value at Start Time of the attribute "Attribute" in the sibling element "SiblingElement".
The "ContentProperty" changes what property of the Attribute is selected (I couldn't find a list of what is what, but they can be gotten by looking at other DeliveryFormats).
This is "simply" a GUI limitation for setting it up, Once correctly added via PI Builder, the attribute even shows up in the designer.

Is this in the road map?
Our notifications broke after we upgraded to 2018 release. Please restore this feature asap.

Need to put this back the way it was. As it is now. Notifications is worthless to me.
Ben Bohringer commented
We too have this issue.
notification were still working after upgrade but unable to update the data reference in the notification when we made changes to our element hierarchy. Does any one have a work around for this?
Only option I can think of is to duplicate all the required attributes from child elements in the reference element?

We started to receive complains about having that very used feature removed. The curious thing is that old PI Notifications grabbing child element attributes values are still working. So we just need kind of a "Add" button. !
Our problem is that this worked in "older" versions and we have (had) a lot of notifications with this feature ! So for us it would be urgent to get this function back !

Another thing, it would be show attributes from child elements. Like, a rollup Notification.
