Good day to everyone,
I would like to request your valuable assistance with a problem that I have been trying to solve during the last couple of days. The scenario is the following: I have a table with three columns, Group, Category, and Action; an action can take place multiple times within a category, but I only need to know if the action took place at least one, and then count in how many categories that action took place and then combine the results by Group.
I am attaching to this post the sample of the exercise, I would greatly appreciate any type of guidance or advice I could receive in order to solve this issue.
