Good morning everyone
I'm currently working in a PI Processbook display, in wich one of the elements has to be the acumulated values of a tag from the beggining of the month to the current time. I added a PI Calculation Data with this expression
But is not giving me the right value.
For reference, the value should be a number above this one;
Am I using the right function? If not, wich one I should be using?
I searched through the Help section of PI Processbook but I didn't found what I need,.
Thank you very much in advance
