Asset shutdown, still planned posted in cents

Hi everybody.

I'm having an issue in some Assets:

The Asset is shutdown from 01.03.2013.

In planned posted appears +/-0.01 in every month.

In March, April. May this +/-0.01 has been posted.

For next months the planned posted appears with +/-0.01.

How can I stop that planned posted when the asset is shutdown?

Thanks in advance.
