Variances due to Changing of Work Centers in Part List

Hello,

I would need a help on configuring below mentioned scenario in Manufacturing.

There are 2 Work centers available to process one Manufacturing Item. One work center is Automatic machine where there are 2 Crew Size and Machine & Labour Hours are 10.

Whereas the other Work Center is Manual machine where there are 2 crew size and Machine & Labor Hours are 20 resp.

Now the concern is planner can plan the manufacturing item on any of the Work center while creating Work Orders. So we have define Automatic Work Center as a default Work Center in Routing.

But on the day of production, it will get decided whether to continue the Work order on the same automatic Work Center or to run it on Manual Work Center.
