set production order fields to 'non-modifiable'

Hi All,

I have a requirement to set production order fields as non-modifiable when the order status is CNF (Final Confirmation), PCNF (Partially Confirmation) or TECO (Technically Complete).

Also, goods movement should not be possible against orders with TECO status.

If both TECO and confirmation are revoked, the order fields should be modifiable via transaction CO02.

Please let me know how to achieve this using a Status Profile and User Statuses (transactions OPJH, BS02).

Thanks.
