Currently analysis runtime information can be accessed programmatically using the AFSDK (AFAnalysisService.RuntimeInformationFields - https://techsupport.osisoft.com/Documentation/PI-AF-SDK/html/POSIsoftAFAnalysisAFAnalysisService_RuntimeInformationFields.htm). However, there are no fields which can be specified corresponding to backfilling/recalculation status of an analysis.

Adding a field for the aforementioned property or introducing a new method which could expose backfilling/recalculation status would be helpful for finding backfilling/recalculation errors programmatically. This approach should be much faster than finding analyses with backfilling errors in PSE.
