maxOver Function?

I have this Tableau calculation I am trying to mimic. I think I have to use maxOver in this case. I’ve tried this.

maxOver(traffic,[{marketplace_id},monthending, {page_type},{device_type}],PRE_FILTER)

However, my number is off from the Tableau calculation. Any help would be appreciated!

Do you mind to provide your dataset and expected calculation results? Thanks!

maxOver is not a replacement for FIXED LOD in Tableau.
I believe we just enabled the new functionality for all accounts that allows user to specify partitions as the second argument for many of the simple aggregation functions. Can you check if the following works in your account already?

max(traffic_o,[marketplace_id, monthending, page_type, device_type])
