You did right by creating a new question but please avoid responding to old threads like you did here, especially if this means duplicating your question.
The Management plug-in of PI System Explorer provides access to the Analysis Service Configuration. Right-click into the pane at the right hand side and chose the corresponding option to open the following dialog.
Please note that these settings are global and be cautious when adjusting the configuration. I've just set AutoBackfillingEnabled to False and tested it. According to my observation, PI Analysis Server picks up the change without a service restart.
Thanks for your inputs, but if i set the Auto Backfilling Enabled to False this will effect the complete Analysis in the AF.
I don't want to do that, i am looking for an option to Disable backfilling for selected Analysis - will that be possible ?
Also , i would like to know though the output Attribute DR for the analysis is Analysis and backfilling is not possible for that , but i can see error pop-up as i highlighted above.
I recommend you to vote for this enhancement request. Its status tells me that there are currently no plans to allow disabling auto backfilling on a per Analysis / per Analysis Template base.
Please see KB01586 - The Analysis Data Reference: Use Case, Configuration and Caveats. The Analysis Data Reference does not support to store output history as explained in the help bubble showing when you hover the mouse cursor over the error.
