Change Work Center during production order confirmation

Dear All,

I must to modeling this situation:

I created an production order. In routing I used an work center A.

After I confirmed a half of quantity, the work center A was damaged and I must to change it, with the work center B.

The system allow this change, but when I checked the costing, the situation isn't real. The system counted the costs just for the work center A, and no for work center B.

My question is: it's possible to change the work center, during production order confirmation and the costs updated with new cost?

Thank you for your answer!

Regards,

Marian
