costing run with more costing variant

Hi,

I have 4 costing variant A,B,C,D with 4 valuation variant for 1 one company code.

If I run CK40n for valuation varian A end I release the price, when I want to mark price of another material costified with valuation variant B, the system doesn't allow this operation because for the company code exists one mark with costing varian A.

Is there any way to solve this problem?

Thanks in advance

Regards
