I have PI server 2012 and no AF server. I have the following data points.

How to igoTag_Name: Pallet

27.04.18 08.06:40      0

27.04.18 09:08:20      1

27.04.18 09:40:06      2

27.04.18 10:20:07      3

27.04.18 10:41:33      3

27.04.18 11:30:15      4

27.04.18 12:01:37      5

27.04.18 12:53:28      0

27.04.18 14:20:46      1

27.04.18 15:02:25      2

27.04.18 16:15:23      2

27.04.18 16:16:01      0

So in all there were 7 pallets made. But if use PIAdvCalcFilVal function and count the events with a filter where ("Pallet"<>0) I get a value of 9. And this is wrong. How do I ignore duplicate values in my event?
