This becomes too demanding the higher the number of users. Is there a way to simplify this based on a database load or something else i.e. without having to type each QVUser()?
You'll have to initial-data-reduce the values for field View. What you could do is name the flag columns in your security Excel the same as the values in field View (and probably the Sheet labels), and create a reduction table based on these values.
For example with your demo data, User1 would only find View values 'Patents' and 'FDA' in the listbox (aside from the default sheets that everone can see). User2 would find view values 'Generics' and 'Shopping' in that listbox.
