Automatic capacity allocating to other work centre during overload

Dear all,

I face the following situation in which lets say i have two work centres W1 and W2 in a plant. In routing i mention W1 work centre for all 3 operations. Now work centre W1 gets overloaded,is there any tcode or way by which i can share the load to work centre W2(not in routing)?

In CM25, we have to choose multiple work centres (else only one work centre is displayed as in routing) and same is passed to next leveling screen and there we need to do drag and drop. Even if i select all planned orders by choosing edit -> select -> chart and dispatch all, all planned orders goes and sits in the work centre which i mentioned in routing only.

Is there any way where it gets allocated or distributed to other work centre in case of overload. Is it possible to achieve the same with any hierarchy or ind.caps or sequences etc..?

Some less complicated way for the client users would be appreciable.

Kindly help me..
