STO proposal through scope of planning ?

hi Gurus,

is it possible to get STO proposal through Scope of Planning.

the scenario is like this i have 2 plants and i configure scope of planning for all the 10 plants.

plant   Req quantity  exist quan    planned recp    

A        500                  200                150

B        600                  300                 500

in the above case if i run the scope of planning will system transfer the planned recp of plant B to Plant A because planned recp of plant B is more than its req quantity. is it possible through standard and what is the scope for development.

regard

mahesn.
