Use this window to access the Week and Day tabs. You can register time weekly or daily. The difference is that the Day tab includes some extra options, e.g. you can write internal comments and invoice comments. Using the Week tab saves time in those cases when you register time on the same report code several days in a row. Time registration normally updates both internal and sales quantity in the Project Transaction window.
For the description of each tab in the window, follow the appropriate link: Week, Day.
