Attributes set as configuration items are used as variable inputs to PI Analyses expressions. When this analysis is performing calculations based on empirical tuning parameters, a tracking method is needed to record changes of these parameters. Adding annotation capability to element attributes set with "Configuration Item" property would provided a tracking method.
Ex:
2020-06-15 Component replaced with new. Adjusted tuning parameter to value ### in order to reset wear rate.
This could be done using a table with timestamp column and using a table lookup data reference (TLDR) attribute to show the value. If you want the changes in value to be reflected over time (say for backfills or trending), the timeseries data setting of the TLDR could be used. A third column to hold the reason for the value update could also be added to the table.
