Hi, so i've created pi points that store time values for them to reflect on a PI Vision Display:
Start of Year - basically start of the year date
Month = Month('*')
Year = Year('*')
Quite simple enough. What i've encountered however is after Backfilling ('*-3y' to '*') and checking the values in SMT, they reflect BUT after a while, i check again and the events beyond a 1yr span (outside of Aug2017-aug-2018) get deleted for the tags above. I have no idea what's happening here. Can someone help me?
