Be able to disable auto backfilling on a per analysis basis
Currently in the analysis service configuration there is a parameter called “AutoBackfillingEnabled” which affects the analysis calculations in a global basis. It would be great if it were possible to disable the auto backfilling to individual calculations.
In my case, I'd like PI Points that are output of an analysis to also be source tags for OPC output PI Points. When backfill of the analysis occurs, it triggers writes to the PLCs with unwanted old data. Since automatic backfill for other analysis is desired, we'll need to develop some other solution.
In some integration solutions we've worked with, where external systems receive PI data, backfilled data is not desired. So having the flexibility to disable backfill for specific analysis would open up more "off the shelf" possibilities involving PI AF.
I have some analyses mapped to attributes which have no history output saved, Auto Backfillings always give unecessary errors for the analyses.
