Hi Manasa,
in material master basic data 1, there is something called as X-plant mtl status, here you can block material for all plants.
In Sales: Sales org 1 view, there is X-Distr. Chain status, where you can block material for sales for specific sales area.
Regarding Labor Value, I am not sure if you can block but if you remove Labor value catalog assigned to Labor value, it won't get determined or will be selection option on RO
Please let us know if it works for you.
Thank you
