Hi,

I want to keep the latest data point which is processed in a datastream variable. So technically I need just one value in the variable and discard all the older ones.

Can this be done somehow? I was thinking about using filters but i don't think i can use it for this scenario.
Any ideas as to how to do something like this is really appreciated.

Thanks a lot
