Manipulating Tableau Function to Work on QuickSight

I’m trying to manipulate a Tableau function to QS. My output is not getting the same number, so I am doing something wrong here. Can anyone help with this?

Tableau - { FIXED [marketplace_id],[monthending],[page_type],[device_type]:MAX([traffic_o])}

QS - maxOver(traffic_o,[{marketplace_id},monthending,{page_type},{device_type}],PRE_AGG)

@Rushabh_Vora , are you able to provide guidance on this?
