Default 200A Panel w/150A Entrance Cable?

Is it a problem to install a 200A Circuit Breaker panel w/an existing 150A entrance cable. Someone told me that would lead to an over-fused circuit, but thinking it through, the greater capacity "down stream" shouldn't be a problem if there is less current coming in.

Not a problem is you use a 150 amp breaker in the 200 amp panel. The cable will not limit the current. Curent will flow until the cable melts. The breaker protects the cable.
