Project Scheduling aligment with Actual Date

Hi,

I have Scheduled a Project in Planning Board and my first Activity (Architecture Design) was scheduled to finish at 30.06.2014.

While the the next dependant activity was scheduled to start the next day 01.07.2014.

Now my first Activity (Architecture Design) is finalised & confirmed (see actual in yellow) earlier than planned.

Please can you tip, what shall I do to reschedule the project so that next activity is also planned to start earler (the next day after first).

Or where do I set up this logic "if the activity on critical path is finished earlier, reschedule the whole project to as early as possible".

I understand I can;t chage "Basic Dates", but the forecast dates shall reflect the state of actuals - right?  

Cheers,

Daria
