How standard Frozen cost behave in new financial calender?

Hi,

We are using Oracle R12. Every year we update our standard cost in system and update new cost to Frozen. But this year there is no change in our cost. So do we need to do any additional activity in system to carry on the current cost to new financial year or same cost will be automatically effective next year as well.

If someone can help on this, it will be highly appreciated.
