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.

    We have many analysis where backfilling is not required. The attribute we link the analysis to is only for information purposes (instantaneous data) which is not required to be reorded in the historian. Whenever we check the AF system for errors we always see the "requires mapped output to be configured"even though we know it's not an error we need to fix.

    The correct name for this parameter is AutoBackfillingEnabled. The term "EnableAutoBackFilling" was improperly used in case # 800600.

    I have some analyses mapped to attributes which have no history output saved, Auto Backfillings always give unecessary errors for the analyses.

    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.

    Same need as Jackie Li (Comment from Vendredi 26 octobre 2018). My need is to beabble to flag "Backfillable" analysis. Means I can choose the analyses I want to integrate into the AutomaticBackfilling.

    Also same issue as Jackie Li and PDUHAMEL. We have some analysis that don't need history. This makes O&M more difficult because we always see errors. It would be better to have the ability to choose which analysis participate in backfill.

    It whould be really create if you can adjust this per analysis. I'm using a custom datareference to trigger the analysis (nothing special for the analysis). This CDR will only trigger the analysis when all inputdata is available for a certain output timestamp. The CDR can control the backfilling by itself (gap between last output and progression of the inputs). This works really great, but only if I switch of the AutoBackfilling setting. Yes please, make this adjustable on a per analysis basis!
