Hello, I am working on building a report (Report Tool) that includes a Date column and the related date would be an existing Tag's Timestamp Property (Tag called Trigger), because that's when we know the data was triggered/recorded. I have created both Reference & Expression Tags with little success - setting the Reference Tag's Source Tag Path to the Referenced Tag's Timestamp property ([.]Trigger.Timestamp).

 ![ReferenceTagInfo](https://us1.discourse-cdn.com/inductiveautomation/original/3X/6/2/62c59d4bc2c00f84fd0865f42b2acae59d9b219b.png)

I then import it to the Report's Tag Historian Query but when brought into Design it gives me a fixed date that does not adjust according to the Date Range options I assigned for the Query.

What would be the best way to Reference an existing Tag's Property to be put into the Report Tool?

Tip: you've tagged the question as "Perspective" (which it isn't). I've changed it to "Reporting" (which it is).
