Thanks Steve
I really appreciate your response and it is very helpful.
We need data in history mode with multiple data points.so we can not use current mode and rowcount as 1.
I am assuming that to achieve this either I have to use interpolated view or for event view OSI PI have to remove archiving so that it will maintain single data point for one timestamp.
Please let me know if my assumption is right or is there any better way.
However with rowcount 1 it is returning the first value.
