How to do same process for multiply data sets?

iven

I have 12 data sets and I want to do the same transpose and filter example range operators on them. The loop files operator makes me confuse. Is there any simple way to do that?

Hi @iven, 
If you use a loop file operator to open your data sets, each action, such as working with filter operators, etc., that you run inside the operator will work on each data set consecutively.

please check this video from the RM academy.
