Allow dynamic PI Point data references for analysis outputs

Created on behalf of a customer: In order to use fewer attributes in an element, a customer hoped to output analysis results to an attribute with a dynamic PI Point data reference. Unfortunately, with the use of substitution parameters or with string builder, the "dynamic" PI Point data reference will only resolve the tagname once - upon creation (or when the data reference is manually updated). It doesn't act dynamically because it's not actually designed to act that way. The current workaround is to create all necessary output attributes, categorize them, and flatten/hide/minimize all categories containing the attributes that are not important at the time to reduce clutter.

    Thank you very much for sharing your feedback on the PI Server. After further evaluation, we have decided to decline this item, as we are not planning on implementing it in the near future due to other high priority items across the PI System. Thank you for your feedback, and know that we are listening and reviewing every item that gets submitted!

    I am the customer who requested this. Another workaround would be to have a function in AF or analytics to force a substitution parameter resolve.

    The same has been also requested for any attributes used by an analysis that get their PI point name from a table. Currently, the attribute gets resolved only during analysis startup. Changes to the underlying table require the service restart.

    hello everyone, someone can give me a demonstration of the workaround described by Ryan Biggins, please.
