Capturing donor frequency:
We want to count the number of donations a donor has given per procedure. The amount of donations is the bucket I want donors to fall into. So, if we had 100 donors give 4 donations, we want those donors to fall into the bucket '4', and then we would count the unique donor ids.
The part I am struggling to noodle out is that they want to be able to filter by procedures and any combination of procedures. There are many procedures, so if I were to try a rank and window approach, I would have to think of every possible combination of procedures and create a rank and window for each one (right?)
I thought maybe I could try a "sum of donations over partition by donor id" beastmode, but it doesn't group by the sum of donations, I just get separate rows (example 10 rows of 2 donations), so that did not work for me.
Side note: the buckets would be 1-24, and then one that is 25+
I've attached an image of sample data (top section) along with a picture of the idea I am going for.
I appreciate any advise, thanks
