create a new column based on inputs from 2 other columns

Hello everyone,

I have a set of data, and I need to calculate a new column.

This new column will have to be “True” (for filtering purposes) when columnA=max(columnA) over id (this id is a unique value, that appears in duplicates).

thank you for all your help.


Math node can give you column maximum. If you want it grouped then maybe a group loop could be a way to go where you calculate the col max for each group and then use rule engine or sth to check whether to add a true or false.
