I have a CSV file with a bunch of columns... one of them is status, which is a field which I split ALL on a custom value, which creates N new split fields. I then pivot these N fields, in order to further refine via a single status Split field, creating a cal field called timestamp (ephoc). From there I aggregate on on the MAX timestamp field grouped by a unique value. Finally this gives me all the LATEST timestamps along with their unique value. My question is how do I sucessfully join or merge this back into my intial pivot and then filter my pivot 'Status Split'
