How can I disable the output of email and phone number from "Patron" in the report? https://lists.katipo.co.nz/public/koha/2025-May/061408.html
Have you tried the column configuration as suggested in the thread? you can permanently remove the borrower column that way already.
I don't need to delete the column permanently. I want to see "cardnumber" and "surname", "first name", "middle_name".
