Application Access details
If you do not have access to the code from the applications accessing your database, using the Profiler over a reasonable period of time, as commented by @nelson-casanova, is your best option. 

If you do have access to the application code, check there.  Also check the definition of any stored procedures, functions, or other views.

I presume you need the column removed for security reasons?  If so, perhaps you can modify your view to use IS_SRVROLEMEMBER and return those columns only when authorized? Copy your view and name it 'original_view', copy your view and edit your columns then and name it 'modified_view.  Now edit your view and call the new views:

IF IS_SRVROLEMEMBER ('role_view_all') = 1      
   select * from original_view;   
ELSE IF IS_SRVROLEMEMBER ('role_view_all') = 0      
   select * from modified_view;


If there is an application that you missed in your Profiler run, you can temporarily add that application's user(s) to the 'role_view_all' role, while developers sort out a workaround or fix their queries.
