Starting an Action Immediately 
You can schedule actions in the DBA Planning Calendar. These are then performed at the specified time.
In some cases, however, you may have to execute a scheduled action immediately, or restart a previous action; for testing purposes, for example, or if an action fails, or in the case of a resource bottleneck. In these cases, immediate action is required.
Prerequisites
Procedure
Open the DBA Planning Calendar (Setting Up and Using the DBA Planning Calendar).
Double-click on the calendar cell containing the scheduled action or previously executed action desired.
A dialog box appears with the details of the action. Check the action parameters.
Choose Re-Execute.
If you are sure that the action parameters are correct, simply carry out the following steps in the DBA Planning Calendar:
Place the cursor on the calendar cell containing the relevant action.
Choose Execute.
Select a task.
Choose Execute.
Result
The action is scheduled for the current time.
