You have to use the Re-organization through CKR1. But be cautious of this transaction if you are using in production. If you forget to do a proper selection, you may have to repent, as it may wipe out the whole cost estimates that supports the already released cost .
Be patient and restrict as much in selection Choose the material, plant and select future cost estimate.
