Does the PI Performance Equation (Calculated) Points/ Tags update and back fill in case of Data Latency?

Hi friends,

Due to a recent Network Latency issue that we encountered yesterday, the PI Points were not updating in Real Time.

After the Network covered, I noticed that the Data Back-filled itself automatically as it should.

However, I noticed that all the PI Performance Equation (Calculated) Points/ Tags did not Back Fill itself based on the new set of Back-filled Data.


Will the Calculated Points recover and correct itself and back-fill with new calculated values?

If not, Is there a solution for this?
