You need to set WC unit of measure to minutes and you can use fields 'Starting Time', 'Ending Time' and 'Concurrent Capacity'. NAV uses the contents of these fields to calculate the 'Run Time'. Calculate pattern is: 'Ending Time' - 'Starting Time' * 'Concurrent Capacity' = 'Run Time'.
- 'Starting Time' = Starting time of capacity working
- 'Ending Time' = Ending time of capacity working
- 'Concurrent Capacity' = Number of employees who working in the same time on WC.
