When you change the run control to a certain larger timestep (i.e. daily to monthly), you now have the option to aggregate input slot values. The aggregation function is based on the unit type of the slot. For more information, see Synchronize From Run Control in User Interface.

The weekly timestep is no longer available for selection in either the run control or slot range configurations. This rarely used timestep was not fully implemented so it has been removed from the interface. If you have a model or slots with a weekly timestep, they will behave as before.
