Hello Alteryx community!
I'm new to using Alteryx Designer so this question might be trivial, sorry if it is!
So, here's what I'm trying to do:
I have a list of 14 unique keys, here's a sample:

I also have a table containing hundreds of records for items. An item can be inside this table for a maximum of 14 rows (1 for each of the 14 unique keys "Tempo Key LOC+SoldTo").
With a Summarize tool, I've been able to idenfity items that do not have 14 rows, as an example, here, the item "44000875" is only found 9 times:

Now, I need to somehow find exactly which 5 "Tempo Key LOC+SoldTo" are missing, and I need to do that for every items.
How would I go about doing such a thing?
Thank you very much for your time,
