    How to Re-Calculate PI AF analysis?




      In AF,


      Is there any option for Re-calculating AF analysis?


      Present Configuration:

      I have created one expression analysis and output of it is mapped to an PI Point referenced attribute.



      I have modified the expression and back-filled for past time. But in Data Archive it was not affected, because during those timestamps old values are there. Once, I deleted those values and back-filled again in the AF, then it got reflected into archive.


      Is there any option to re-calculate, without deleting the history values in Archive?
