Define the timespan of the schedule in the VPS

The timeframe specifies the time range covered by the timescale, either fixed by absolute values or relative to the workday.

Set the starting and ending date of the time scale either as absolute value, or depending of the working date: “-4W” in the "Starting Date" field will prepone the start date of the time scale by four weeks to the work date calculated by NAV, whereas “+3M” in the "Ending Date" field will postpone the end date of the time scale by three months after the work date.
