I am looking at yesterday’s flow and elapsed time totalizers in a report table. The timestamp is for the following day (day when I am looking back at the data). Is there a way to move the the timestamp one day back? I tried a superfluous tag historian query and using that timestamp in the row and it didn’t work. Would only give me the same day for all rows.
IIRC There was a bug in the date picker being off by 1 day that was resolved in 8.1.49. Before you edit the timestamp, be sure you're actually grabbing the correct day and it's not just pointed to one day off.
You should be able to go to the data tab and then make a new parameter and put the dateArithmetic function in there to get the new date you want. Then you use that new parameter name as the key in your report.
