Hi everybody!


I'm traying to create a PI Vision Dashboard to monitor the energy production of my power plant for the previus day, among other KPIs of my interest, using AF Analysis calculations. I would like that these values keep static during the current day if i access at any time, because I want to see just the production of yesterday, and the next day, at 6:00 am, I would like that the calculation will be executed for the current day. For this purpose, I set this in AF:

As you see, the TimeStamp is set using Bod('*') and Bod('*-1'), the start and the end of the previus day, I just want one calculation at day. It seem that this method may work but then, when I access to my dashboard in PI Vision, I see that these values are being recalcuation every time I change the time palette in PI Vision: 

If I acces to my dashboard right now the value retrieve is different compared with one hour before for example...

What am I missing? Is there another way to do what i want properly?


Thanks for your help!
