To get a proposal for the planned arrival time depending on the planned departure time, you can use the Set Planned Arrival Time function in the Create TU and Change TU dialog boxes. The system proposes a planned arrival time using the in-yard time you have entered in the transportation unit (TU) profile of the TU. If you use Set Planned Arrival Time while creating a TU, the system selects the Planned Times Fixed checkbox if the assigned outbound delivery orders are for routes that have fixed route departure schedules.
