    How to Re-Calculate PI AF analysis?

    Navaneethakrishnan

      Hi,

       

      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.

       

      Question:

      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?

       

      Thanks,

      Navaneethakrishnan V.
