Hi,
I am looking to compare information across two different rows in my dataset. As of now, individual files come into my dataset with "FilePeriod" dates. I want to see if the "Action Date" column changes between different file periods and then show this in a table with other data. The data is structured like this (simplified):

How would I create / calculate Column 3?

@sgraber12 , try a new column like
New column
var _1 = maxx(filter(Table,[File Period]<earlier([File Period])),[Action Date])
return
if(isblank(_1) , "NO", if([Action Date]<>_1,"YES","NO"))
