I have a spreadsheet where in TAB A I have a database with the "raw" data imported from another db, where I have some products with unique ID's and a few other columns.
What I'm trying to do is on TAB B, using an arrayformula, is count all of the unique numbers for the specific ID, I left an example on TAB B on the top rows using QUERY formula.
here is the spreadsheet link if you wanna take a look at the data: https://docs.google.com/spreadsheets/d/1-pFeQWVD_0fpBdC-GzHBlnr92bGDQn-6kqEdWfTAkPI/edit#gid=487890997
Thanks in advance for the help!!
