Hi all,
I'm trying to add a column in the "Timesheets to Approve" view corresponding to the timesheet/week number. When editing TreeView (developer mode), I need to add code like <field name=" ??? "/> corresponding to the desired field. 
When passing the mouse over the Week number field, it should appear the field name (with some other info), but it doesn't. 

Anyone knows how to find that field name or at least the name itself?
Thanks
