I'm working on a complex project with many interdependent analyses, and have noticed occasional "calc failed" messages in the destination tags of the output data stream. These seem to go away if I back-calculate (which indicates to me that there are likely things happening in an unexpected order in the data). I'm not sure yet whether I'll actually need this, but has anyone found a way to force a regular back-calculation of analysis data? I'm thinking of something that would recalculate an analysis every 12 hours, with each iteration covering the last 48 hours' data (or something similar).
It seems to me this ought to be possible in PI-ACE, but have no experience yet using the AFSDK in that environment.
