Finish (Usage-Based Optimization Wizard)
In this step of the wizard, you save the aggregations. You can process the cube while you save the aggregations, or process it at a later time. If you are designing several cubes, you can postpone processing and process them all at once.
Options
Process now
Select to save the designed aggregations for the cube or partition and process the cube. The new aggregations will be available for use by queries sent to the cube only after processing is completed.
Save, but don't process now
Select to save the newly-designed aggregations for the cube or partition, but to delay cube processing to a later time. Your queries sent to the cube cannot use your new aggregations until processing is completed.
Finish
Click to save your settings and, if you selected Process now, process the object. If you selected Process now, clicking Finish opens the Process dialog box, in which you can view the progress of the operation.
