Calculated field and hidden column in view mode

Teste1645 you can show different columns in different views, but any user who know how lists work will still be able to change the view to show all the columns. You might want to consider using a Power Apps customised form for your list (from Integrate -> Power Apps -> Customised form at the top of your list) which you can embed as a web part on a SharePoint page. This will allow the user to enter the details they need to enter but make it harder for them to see all the columns. In my example video attached I have put both views of my timesheet list on the page as list web parts and also added the Power Apps web part for the form (you of course might not want to display any views on the page but just have the form). The user enters/selects their time information and the form does the calculations before saving the details to the list.

Come back with any questions about this.
